You're also planning on building a web or desktop app.
Your development team is most comfortable with web technologies.
Performance optimization isn't critical to your project.

Conclusion

Both Ionic React and React Native are great ways for mobile application development. React Native may be a better option for teams targeting iOS and Android only, with more traditional native developers or advanced js developers and an existing repository of native controls. This describes why React Native is so popular among consumer app start-up companies with a background in native app development. Ionic React is a better option for teams with traditional web development skills and libraries who would like to focus on mobile and web (as a Progressive Web App). This explains why Ionic has been so effective with start-ups and enterprise teams with a background in web development. We believe that both developments will exist side by side because they address different requirements in the ecosystem. We are delighted to discuss which platform is best for your team.

Jira Integration with GitHub

The Jira and GitHub integration synchronizes development across tools and leverages automation to eliminate manual steps and reduce delivery time. By integrating GitHub code with Jira projects, developers can focus less on updates and more on creating amazing products.

OBJECTIVE:

To configure github with jira through pytest to update results on jira tickets, When Merging a Pull Request the github workflow will be executed, After the workflow execution the status of the jira tickets will be updated as per the result of github workflow execution through pytest

What is Jira?

Jira is a web application used as tracking tools for tasks like epic, story, bugs and so on. Jira is available as an open source and paid version.

Why do we use Jira ?

It is used for various kinds of projects like business projects, software projects and service projects Applications like Github, slack, jenkins, zendesk etc can be integrated with jira. By using jira a ticket can be created for each type of task to monitor application development, Here we integrate Github with jira through the pytest framework.

What is Pytest ?

Pytest is an automation testing framework in python which is used for testing software applications.

Why do we use Pytest ?

Pytest is a python framework, using pytest we can create TDD, BDD as well as Hybrid testing framework used for automation testing like UI, REST API and it is flexible for supporting different actions. Here we are going to execute the test cases that are triggered from the github actions workflow and update the particular jira tickets based on the workflow execution results.

What is Rest API ?

REST is abbreviated as (Representational State Transfer) it is an architectural style for interacting between the client and the server, the client sends the request and a response is received from the server in of JSON, XML, or HTML, but json is most commonly used response type because it is readable for both human and machine. Here we interact with the Jira through Rest API, the API Endpoints we are using to interact with Jira is given below

EXECUTION FLOW OF GITHUB FOR JIRA THROUGH PYTEST

To update the jira tickets through pytest, we need to know about the Github workflow execution, Jira Rest API endpoints, pytest configurations

Things we need to know for execution:

To create a github workflow file to execute pytest test cases when a PR is merged
To configure pytest test cases with jira API endpoints to send the workflow results

JIRA REST API ENDPOINTS

Prerequisites for Jira API Integration:

Steps to create API Token:

STEP 1: Login to Jira with the registered Email ID Use this link https://id.atlassian.com/login to login into the jira
STEP 2: Click on your jira Profile and click on manage accounts in the popup

STEP 3: Click on Security tab and click create and manage API token

STEP 4: Click on create API Token button:

STEP 5: Provide a label for the token and click create, a new API Token will be generated Copy the token and save the token in a separate file because you cant able to get the same token again

Encoding the API Token:

Encoding the Api token can be done in the terminal, to create a base64 encoded token use the following command In LINUX/ mac-os:

In Windows: You can use the link below to encode the api token online https://www.base64encode.org/

GET Transition ID API:

GET:

https://<JIRA_DOMAIN>.atlassian.net/rest/api/2/issue/<TICKET-ID>/transitions By using this API we can get all the transition details like transition ID transition name The transition ID is default for To-Do, In-progress and Done status, the curl command is given below

Transition Status	Transition ID
To-Do	11
In-Progress	21
Done	31
Issue 1	2
Issue 2	3

Update Transition Status API:

Post :

https://<JIRA_DOMAIN>.atlassian.net/rest/api/2/issue/<TICKET-ID>/transitions This API Endpoint is used to update the transition status of the jira ticket. Ticket ID is passed in the path param and the Transition ID is passed in the body of the request, The status of the ticket will be updated with respect to the transition id, Curl for the following API endpoint is mentioned below, The Transition ID can be obtained by using the Get transition ID API, which is mentioned above

Add Attachments API:

Post:

https://<JIRA_DOMAIN>.atlassian.net/rest/api/2/issue/<TICKET-ID>/attachments This API endpoint is used to add the attachment in a JIRA ticket according to the given Ticket ID and passed file. Use the below curl command

Search API:

GET:

https://<jira_domain>.atlassian.net/rest/api/2/search This API Endpoint is used to get the ticket information using the Jira Query Language (JQL) syntax, the JQL should be passed as an parameter to this API, By using this API we can get the information of all/any of the ticket, An example for JQL to get the ticket information using PR Link which is mentioned in the Github info paragraph field of a jira ticket Example for JQL:

CONFIGURING GITHUB WITH JIRA:

There are two ways in configuring github with jira, one is by providing the PR link in a separate field of jira ticket and the other way is by configuring github app in jira

1. Configuring jira with PR link:

We can able to identify the ticket information by providing the PR link in a Jira ticket
PR Link should be provided in the custom field of Jira ticket
After placing the PR link in custom field, we need to use the Jira Search API endpoint through Jira Query Language(JQL) syntax

2. Steps to configure PR link in Jira Ticket on custom field:

Go to Project Board > Project settings > Issue types
Select the Paragraph field type > Enter the field name and description
Click Save changes

3. Configure github app with jira:

To configure Github with jira,Login into Jira, go to Apps➡ Manage Your apps

Select Github for jira ➡ click connect github organization
CLICK Install github for jira on new organization
On clicking Install github for jira on new organization select the github organization in which you want to install jira
Select repository which you want to configure and click install
Now you can see your git repository that have been configured in the github for jira tab

UPDATING EXECUTION RESULTS TO JIRA TICKET USING PYTEST:

All the test cases and the reports report generation for all the test cases are done using pytest
After the Workflow execution, the build status and PR link will be added as comments and the reports will be added as attachments to the jira ticket, this is done by the pytest fixture. The pytest fixture is used to execute the conditions before and after the execution of test case, the yield keyword is used to execute the conditions after the execution of all test cases

The teardown module() method calls the Jira API Endpoints for Adding Comments and Attachments.

Build APIs in Python Using FastAPI Framework

FastAPI could be a modern, high-performance, web framework for building APIs with Python language. Good artificial language frameworks make it easy to provide quality products faster.

FastAPI could be a modern, high-performance, web framework for building APIs with Python language. Good artificial language frameworks make it easy to provide quality products faster. Great frameworks even make the entire development experience enjoyable. FastAPI could be a new Python web framework that’s powerful and enjoyable to use.FastAPI is an ASGI web framework. What this implies is that different requests don’t necessarily sit up for the others before them to end up doing their tasks. Additional requests can do their task completed in no particular order. On the other hand, the WSGI frameworks process requests in a sequential manner.

ASGI:

ASGI is structured as one, asynchronous callable. It takes a scope, which could be a dict containing details about the precise connection, sends an asynchronous callable that lets the appliance send event messages to the client, and receives an asynchronous callable that lets the application receive event messages from the client.

Does FastAPI need Uvicorn?

The main thing needed to run a FastAPI application in an exceedingly remote server machine is an ASGI server program like Uvicorn.

Using WSGIMiddleware:

Need to import WSGIMiddleware.Then wrap the WSGI (e.g. Flask) app with the middleware. Then mount that beneath a path.

FastAPI Different from other Frameworks:

Let us walk through a journey of building a CRUD application with FAST API and understand how transactions, persistence/database layer, exception handling, and request/response mapping are done.

Building a CRUD Application with FastAPI

Setup:

Start by creating a brand new folder to carry your project called "sql_app".

Create and activate a new virtual environment:

Next, create the following files and folders for fastapi:

Install the following dependencies:

In the sql_app/main.py ,and define an entry point for running the fastapi application:

In this case, we stated the file to run a Uvicorn server. Before starting the server via the entry point file, create a base route in api.py:

Difference between Database Models & Pydantic Models:

FastAPI suggests calling Pydantic models schemas to assist make the excellence clear. Appropriately, let’s put all our database models into a python models.py file and every one of our Pydantic models into a schemas.py file. In doing this, we’ll also have to update database.py and main.py.

Models.py:

database.py:

schema.py:

FastAPI interactive documentation

A feature that I like about API is its interactive documentation. FastAPI is based on OpenAPI, which is a set of rules that defines how to describe, create and visualize APIs. OpenAPI needs software, which is Swagger, which is the one that allows us to show the API documented. To access this interactive documentation you simply need to go to “/docs”.

Structuring of FastAPI:

By using __init__ everywhere, we are able to access the variables from everywhere in the app, similar to Django.

Models:

It is for your database models, by doing this you'll import the identical database session or object from v1 and v2.

Schemas:

It is for Pydantic's Settings Management which is extremely useful, you will be ready to use the identical variables without redeclaring it, to work out how it should somewhat be useful for taking a glance at our documentation for Settings and Environment Variables.

Settings.py:

It is for Pydantic's Settings Management which is extremely useful, you'll be able to use the identical variables without redeclaring it, to determine how it may well be useful for you take a look at our documentation for Settings and Environment Variables

Views:

This is optional if you're visiting render your frontend with Jinja, you'll have something near MVC pattern.

Core views

v1_views.py
v2_views.py

It would look something like this if you wish to feature views.

Tests:

It is good to own your tests inside your backend folder.

APIs:

Create them independently by APIRouter, rather than gathering all of your APIs inside one file.

Logging

It could be a means of tracking events that happen when some software runs. The software’s developer adds logging calls to their code to point out that certain events have occurred. an occasion is described by a descriptive message which might optionally contain variable data (ex. data that's potentially different for every occurrence of the event). Events even have an importance that the developer ascribes to the event; the importance also can be called the amount or severity.

Github Link: https://github.com/keerthanakumar-08/FastAPI

Conclusion

Modern Python Frameworks and Async capabilities are evolving to support robust implementation of web applications and API endpoints. FAST API is definitely one strong contender. In this blog, we had a quick look at a simple implementation of the FAST API and code structure. Many tech giants like Microsoft, Uber, and Netflix are beginning to adopt. This will result in growing developer maturity and stability of the framework.

How to use Apache spark with Python?

Apache Spark is based on the Scala programming language. The Apache Spark community created PySpark to help Python work with Spark.

Apache Spark is based on the Scala programming language. The Apache Spark community created PySpark to help Python work with Spark. You can use PySpark to work with RDDs in the Python programming language as well. This can be done using a library called Py4j.

Apache spark:

Apache spark is an open-source analytics and distributed data processing system for large amounts of data (large-scale datasets). It employs an in-memory caching and an accelerated query execution for quick analytic queries against any size of data. It is faster because it distributes large tasks across multiple nodes and uses RAM to cache and process data instead of using a file system. Data scientists and developers use it to quickly perform ETL jobs on large amounts of data from IoT devices, sensors, and other sources. Spark also has a Python DataFrame API that can read a JSON file into a DataFrame and infer the schema automatically. Spark provides development APIs for Python, Java, Scala, and R. It shares most of its features with PySpark, including Spark SQL, DataFrame, Streaming, MLlib, and Spark Core. We will be looking at PySpark.

Spark Python:

Python is well known for its simple syntax and is a high-level language that is simple to learn. Despite its simple syntax, it is also extremely productive. Programmers can do much more with it. Since it provides an easier interface, you don't have to worry about visualizations or Data Science libraries with Python API. The core components of R can be easily ported to Python as well. It is most certainly the preferred programming language for implementing Machine Learning algorithms.

PySpark :

Spark is implemented in Scala which runs on JVM. PySpark is a Python-based wrapper on top of the Scala API. PySpark is a Python interface to Apache Spark. It is a Spark Python API that helps you connect Resilient Distributed Datasets (RDDs) to Apache Spark and Python. It not only allows you to write Spark applications using python but also provides the PySpark shell for interactively analyzing your data in a distributed environment.

PySpark features:

- Spark SQL brings native SQL support to Spark and simplifies the process of querying data stored in RDDs (Spark's distributed datasets) as well as external sources. Spark SQL makes it easy to blend RDDs and relational tables. By combining these powerful abstractions, developers can easily mix SQL commands querying external data with complex analytics, all within a single application.

- DataFrame A DataFrame is a distributed data collection organized into named columns. It is conceptually equivalent to relational tables with advanced optimization techniques. DataFrame can be built from a variety of sources, including Hive tables, Structured Data files, external databases, and existing RDDs. This API was created with inspiration from DataFrame in R Programming and Pandas in Python for modern Big Data and data science applications.

- Streaming is a Spark API extension that allows data engineers and data scientists to process real-time data from a variety of sources like Kafka and Amazon Kinesis. This processed data can then be distributed to file systems, databases, and live dashboards. Streaming is a fault-tolerant, scalable streaming processing system. It supports both batch and streaming workloads natively.

- Machine Learning Library (MLlib) is a scalable machine learning library made up of widely used learning tools and algorithms, such as dimensionality reduction, collaborative filtering, classification, regression, and clustering. With other Spark components like Spark SQL, Spark streaming, and DataFrames, Spark MLLib works without any issues.

- Spark Core is a general execution engine of Spark and is the foundation upon which all other functionality is built. It offers an RDD (Resilient Distributed Dataset) and supports in-memory computing.

Setting up PySpark on Linux(Ubuntu)

Follow the steps below to setup and try pyspark: Please note that python version 3.7 or above is required. Create a new directory. Navigate to the directory.

Build and enable a new virtual environment

Install spark

To check pyspark version

PySpark shell

Pyspark comes with an interactive shell. It helps us to test, learn and analyze data in the command line. Launch pyspark shell with command line ‘pyspark’. It launches the pyspark shell and gives you a prompt to interact with Spark in the Python language. To exit from spark shell use exit()

Create pyspark Dataframe:

Like in pandas, here also we can create dataframe manually by using these two methods toDF() and createDataFrame(), and also from JSON, CSV, TXT, XML formats by reading from S3, Azure Blob file systems e.t.c. First, create columns and datas

RDD dataframe:

An existing RDD is an easy way to manually create a PySpark DataFrame. First, let's create a Spark RDD from a List collection by calling the parallelize() function from the SparkContext. This rdd object is required for all of the following examples. A spark session is an entry point for the spark to access components. To create a Dataframe using toDF() method, we have to build a spark session and then pass the data as an argument to parallelize. Finally, we use “toDF(columns)” to specify column names as in the below code snippets.

To createDataframe using createDataFrame() method: We have already created a rdd object with data and a spark session. We can use that object in creating a dataframe. We pass the rdd object as an argument for the createDataFrame() method and use toDF(columns) to specify the column names.

Kafka and PySpark:

We are going to use pyspark to produce a stream dataframe to Kafka and consume the stream dataframe. We need kafka and pyspark for the same. We have already setup pyspark in our system, Now we are going to setup kafka in the our system. If you have already setup kafka you can skip this, otherwise you can setup kafka by following these steps: Set up Kafka using Docker compose: Docker Compose is used to run multiple containers as a single service and it works on all environments. Docker Compose files are written YAML files. Now, create docker-compose YAML file named docker-compose.yml for Kfka. Enter the following and save the file. It will run everything for you via Docker.

From the terminal, navigate to a directory containing the docker-compose.yml (which was created in the previous step) and run the below command to start all services:

Output

Now run the below code to get into docker. It will create a new Bash session in the container kafka.

Create Kafka topic named as test_topic by running the below code

Exit from container bash session by using bash-5.1# exit command. Now we have set-up Kafka and have created Kafka topic to produce and consume dataframe.

Produce CSV data to kafka topic, Consume using PySpark :

Produce CSV data to kafka topic :

For that we need a CSV. Download or create your own CSV file Install the kafka-python package in a virtual environment. kafka-Python is a python client for the Apache Kafka distributed stream processing system. With pythonic interfaces, kafka-python is intended to operate similarly to the official java client. In the below code we have configured Kafka producer and created an object with it. In config we have to give info like bootstrap server and value_serializer. serializer instructs on how to turn the key and value objects the user provides with their ProducerRecord into bytes.

Now read data from CSV file as dictionary :

We have created a producer object and data from CSV, To produce data to kafka, iterate to csv data. Now create a py file named demo_kafkaproducer.py in pysaprk_demo directory. Copy the below code to py file. It will read data from CSV and produce data to Kafka topic.

We have produced data to Kafka. Now we are going to consume data stream from Kafka How to read data stream from Kafka topic? To read the data Stream from the Kafka topic, we have to follow the below steps: First, set the packages to environment for pysaprk shell, spark stream, and spark sql

We have setup the environment. Now we have to create a spark session. SparkSession is the entry point to PySpark. Session will be created using SparkSession.builder. Follow the block of code to create sparksession and read stream dataframe from kafka

Now we have consumed stream data from Kafka and created dataframe named as stream_df Below is the block of code to create schema/StructType,

What is schema/StructType in spark ?

It defines the structure of the DataFrame. We can define it using StructType, which is a collection of StructFields that define the column name, DataType, column nullability, and metadata. Below code will write the data frame stream on console

Output:

Now create a py file named demo_kafkaconsumer.py in pysaprk_demo directory. Copy the below code to the py file. It will read stream dataframe from Kafka topic using pyspark, and write dataframe data in console.

Resemblance and Explanation of Golang vs Python

Everyone has been looking for the best programming language to use when creating software and also there has recently been a battle between Golang and Python.

Everyone has been looking for the best programming language to use when creating software and also there has recently been a battle between Golang and Python. I was contemplating which would be the better. Then I learned that Go was created and released in 2009, but it gained popularity quickly in comparison to Python. Both Golang and Python are general-purpose programming languages used to create web applications. These two appear to be very different. In this article, we will look at a comparison of these two languages.

Golang

Golang is a procedural, compiled, and statically typed programming language(syntax similar to C). It was developed in 2007 by Ken Thompson, Robert Griesemer, and Rob Pike at Google but launched in 2009 as an open-source programming language. This language is designed for networking and infrastructure-related applications. While it is similar to C, it adds a variety of next-gen features such as Garbage collection, Structural typing, and Memory management. Go is much faster than many other programming languages. Kubernetes, Docker, and Prometheus are written in it. (developed using this language or written in it)

Features of Golang

Simplicity

The developers of the Go language focus on credibility, readability, and maintainability by incorporating only the essential attributes of the language. So we can avoid any kind of language complications resulting from the addition of complex traits.

Robust standard Library

It has a strong set of library packages, making it simple to compose our code.

Web application building

This language has garnered as a web application building language owing to its easy constructs and more agile execution speed.

Concurrency

Go deals with Goroutines and channels.
Concurrency effectively makes use of the multiprocessor architecture.
Concurrency also helps huge programs scale more consistently.
Some notable examples of projects written in Go are Docker, Hugo, Kubernetes, and Dropbox.

Speed of Compilation

Go offers a much more powerful speed of completion and compilation than several other popular programming languages.
Go is readily parsable without a symbol table.

Testing support

The "go test" command in Go allows users to test their code written in '*_test.go' files.

Pros:

Ease to use - Go’s core resembles C/C++, so experienced programmers can pick up the basics fast, and Simple syntax is easy to understand and learn
Cross-platform development opportunities - Go can be used with various platforms like UNIX, Linux, Windows, and Other Operating systems, and Mobile devices also.
Faster compilation and execution - Go is a compiler-based language so it completely reads the code and executes due to this it executes faster than c,c++, and java.
Concurrent - Run various processes together and effectively

Cons:

Still developing - Still in development
Absence of GUI Library - There is no native support
Poor Error handling - The built-in errors in Go don't have stack traces and don't support the usual try/catch handling techniques.
Lack of frameworks - Minimal amount of frameworks
No OOPS Support

Here is the simple "Hello World" programme in the Go language.

Output:

Let's discuss the above program,

package main - Every Go program begins with code inside the package main
Import “fmt” - its an I/O function.
func main - This function always needs to be placed in the main package.{} Here we can write our code/logic.
fmt.Println - Print function, print the text on the screen.

Why Go?

It's a statically strongly typed programming language with a great way to handle errors.
It allows using static linking to combine all dependency libraries and modules into one single binary file based on the type of the OS and architecture.
This language performs more efficiently because of its CPU scalability and concurrency model.
This language offers support for multiple libraries and tools, so it does not require any 3rd party libraries.

Frameworks for Web Development: Gin, Beego, Iris, Echo, and Fiber

Python

Python is a universal, high quality and very popular programming language. Python was introduced and developed by Guido van Rossum in the year of 1991. Python is used in machine learning applications, data science, web development, and all modern software technologies. Python has an easy-to-learn syntax that improves readability and reduces program maintenance costs. Python code is interpreted when it is converted to machine language at run time. It is the most widely used programming language because of its tightly typed and dynamic characteristics. Python was originally used for trivial projects and is known as a "scripting language". Instagram, Google, and Spotify use Python and its frameworks.

Features of Python

Free and open source

It's free and open source, which means the source code is available to the public. So we easily download and use it

Easy to code

Python is beginner-friendly because it prioritises readability, making it easier to understand and use. Its syntax is similar to the English language, making it simple for new programmers to enter the development world.

Object-oriented programming

OOPS is one of the essential features of Python. Python supports the concepts of classes, objects, encapsulation, and object-oriented language.

GUI Programming support

A graphical user interface can be developed by using modules such as PyQt5, PyQt4,wxPython, or Tk in python.

Extensible and portable

- - Python is an extensible language.
  - We can formulate some Python code into the C or C++ language.
  - Furthermore, we can compile that code in the C or C++ language.
  - Python is also a very portable language.
  - If we have Python code for Windows and want to run it on platforms such as Unix, Linux, and Mac, we do not need to change it. This code is platform-independent.

Interpreted and High-level language

- - Python is a high-end language.
  - When we formulate programs in Python, there is no need to remember the system architecture, nor do we need to manage the memory.
  - Like in other programming languages, there is no requirement to compile Python code, making it easy to debug our code.
  - Python's source code is converted to an instantaneous form known as bytecode. Python is classified as an interpreted language because Python code is executed line by line.

Pros:

Simple syntax: Easy to read and understand

Larger Community support: Python community is vast

Dynamically typed: The variable type is not required to be declared.

Auto memory management: Memory allocation and deallocation methods in Python are automatic because the Python developers created a garbage collector for Python so that the user does not have to manually collect garbage.

Embeddable: Python can be used in embedded systems

Vast library support: Lots of Libraries are available. For Example, TensorFlow, Opencv, Apache spark, Requests and Pytorch etc.,

Cons:

Slow speed

Python is an interpreted language, so the code will be executed line by line, which often results in slow execution.

Not Memory Efficient

Python's auto-memory management makes it unsuitable for memory-intensive tasks. Because of the flexibility of the data types, memory consumption is high.

Weak in mobile computing

Python is typically used for server-side programming. It is not used in the development of client-side or mobile applications. because it is inefficient in terms of memory and processing speed.

Runtime errors

Because Python uses dynamic typing, the data type of a variable can change at any time. In the future, a string could be stored in an integer number variable, causing runtime issues.

Poor database access

Database access is limited in Python. When compared to popular technologies such as JDBC and ODBC, Python's database access layer is found to be somewhat underdeveloped and primitive. It cannot, however, be used in enterprises that require the smooth interaction of complex legacy data. Here is a simple "Hello World" programme written in Python.

Why Python?

Python is platform-independent; it runs on (Windows, Mac, Linux, Raspberry Pi, etc.). Python has a simple syntax that is related to that of the English language. Python's syntax allows programmers to write programmes with fewer lines than in other programming languages. Python is an interpreter-based language. As a result, prototyping can be completed quickly. Python can be processed as procedural, object-oriented, or functional. Frameworks for Web Development: Django, Flask, Fastapi, Bottle, etc.

Comparison of Go vs Python:

Case studies:

Concurrency:

Concurrency is the concept of multiple computations happening at the same time. Concurrency is well supported in Go via goroutines and channels. A goroutine is a function that can run alongside other functions. Channels allow two goroutines to communicate with each other and synchronise their execution.

Output:

Concurrency is the main advantage in Go compared to Python. Because Python is unsuitable for CPU-bound concurrent programming. In python, we use the Multiprocessing concept to achieve concurrency.

Exception Handling :

Output :

Python supports exception handling, but Go doesn't.

Go vs Python: Which is Better?

When it comes to productivity, Golang is the best language to learn to become a more productive programmer. The syntax is restricted, and the libraries are much lighter because there is less code to write; tasks can be completed in fewer lines of code. Python consists of a large number of packages and libraries. Python has the advantage in terms of versatility due solely to the number of libraries and syntax options. However, flexibility comes at a cost, and that cost is productivity. Which language is more productive in this Python vs Golang battle? The winner is Golang, which is designed to be more productive, easier to debug, and, most importantly, easier to read. Python is without a doubt the most popular choice for developers looking to create a machine learning model. The reason for this is that Python is the most popular language for machine learning and is the home of TensorFlow, a deep learning framework built on Python. Learning a programming language like Python, which almost resembles pseudo-code, is an added benefit that makes learning easier. On the other hand, Golang is super fast, and effortless to write and comes along with Go doc, which creates documentation automatically, making the life of the programmer easier.

Conclusion

Python and Golang are winners in their respective areas depending on the specific capabilities and underlying design principles of the language

Flask vs FastAPI – A Comparison Guide to Assist You Make a Better Decision

Flask and FastAPI are python-based micro-frameworks for developing small-scale data science and machine learning web and apps.

Flask and FastAPI are python-based micro-frameworks for developing small-scale data science and machine learning web and apps. Despite the fact that FastAPI is a relatively new framework, an increasing number of developers are using it in their new projects. Is it just a marketing ploy, or is FastAPI better than Flask? We've put together a comparison of the major pros and cons of Flask and FastAPI to assist you in deciding which will be the ideal choice for your next data science project.

What is Flask?

Flask is a micro web framework written in python. Armin Ronacher came up with the idea. Flask is built on the WSGI (Web Server Gateway Interface) Werkzeug toolkit (For the implementation of Request and Response) and the Jinja2 (template engine). WSGI is a standard for web application development. It is used to build small-scale web applications and Rest API Flask's framework is more explicit than Django's framework, and it is also easier to learn because it requires less basic code to construct a simple web application.

In this real-world top Companies are using Flask

What makes Flask special?

Lightweight Extensible Framework.
Integrated unit test support.
Provided development server and debugger.
Uses Jinja templating.
Restful request handling.

When should you use a Flask?

Flask is old and it has Good Community support
For Developing web applications and creating a quick Prototype.

Flask Web Application Development

Creation of a virtual environment

The venv environment is being restarted.

Database.

Mode Debug
Creating a User Profile Page

Handling errors

1. Virtual environment creation

2. Making Necessary Installation

Build a sample webpage using Flask, it will return the string

After Running the application, we need to visit http://127.0.0.1:5000/

Pros

Flask has a built-in development server, integrated support, and other features.
Flask Provides integrated support for unit tests.
Flask Uses Jinja2 templates.
Flask is just a collection of libraries and modules that helps developers to write their applications free without worrying about low-level details like Protocols and Thread Management.
Because of its simplicity, Flask is particularly beginner-friendly, allowing developers to learn easier. It also allows developers to construct apps quickly and easily.

Cons

Flask makes use of Modules, which is third-party participation that might lead to security breaches. Modules are the intermediary between the framework and the developer.
Flask does not create automatic documentation; They need several extensions like Flasgger and Flask RESTX and also require additional setup.
Flask has a single source, which suggests that it will handle each request one by one, therefore regardless of how many multiple requests there are, it will still take them in turns, which takes extra time.

What is FastAPI:

FastAPI is built in ASGI (Asynchronous Server Gateway Interface) and pydantic, Starlette. This framework is used for building a web application and RestAPI. In FastAPI we need uvicorn to run the server. There is no built-in development server So the ASGI server Uvicorn is required to run the FastAPI application. The best thing that we Highlight in the FastAPI is documentation. It will generate documentation and create Swagger UI. which helps the developers to test endpoints effectively. In fast API, Also includes data validation and returns an Explanation of the error when the user enters the invalid data. It implements all of the OpenAI requirements and Swagger for these specifications. As a developer we will concentrate on developing logic; the rest is handled by the FastAPI.

In this modern world, the top Websites are moving to FastAPI. The website was developed using FastAPI.

When should you use a FastAPI?

Has Good speed and performance when compared with Flask.
Decreasing bugs and Errors in code.
It Generates Automatic documentation
Built-in data validation.

What makes FastAPI special?

Fast Development
Fewer Bugs
High and Fast Performance
Automatic swagger UI
Data validation

1. Virtual environment creation

2. Making Necessary Installation

Build a webpage using FastAPI, It return string

After running the application, we need to visit http://127.0.0.1:8000/docs or http://127.0.0.1:8000/redoc Docs fastapi

Redoc

Pros

FastAPI is considered as one of the fastest Framework in python, It has an native async support and provides a simple and easy-to-use dependency injection framework. Another advantage to consider is built-in data validation and Have Interactive API documentation support .
Dependency Injection support
Fast API is based on standards such as JSON Schema (a tool for validating the structure of JSON data), OAuth 2.0 (an industry standard protocol for authorization), and OpenAPI (an open application programming interface).

Cons

In FastAPI there is insufficient Security and also it will support OAuth.
Because FastAPI is relatively new, the community is small compared to other frameworks, and regardless of its detailed documentation, there are very few external educational materials.

Difference between Flask and FastAPI:

Both offer the same features but the implementation is different. The main difference between Flask and FastAPI is that Flask is built in WSGI (Web Server Gateway Interface) and FastAPI is built in ASGI(Asynchronous Gateway Interface). So, the FastAPI will support concurrency and asynchronous codes. In FastAPI there is automatic documentation for Swagger UI(docs and redocs), But in Flask we need to add some extensions like Flasgger or Flask RESTX and some dependencies setup. Unlike Flask, FastAPI provides data validation for defining a specific data type and it will raise an Error if the user enters an invalid data type.

Performance:

FastAPI uses an Async library which is helpful to write concurrent code. Async is greatly helpful for doing tasks that involve something like fetching data from API and querying from a database, reading the content of the file and FastAPI has ASGI whereas Flask is a WSGI Application

Data Validation:

There is no data validation in Flask. So Flask allows any kind of data type. In Flask the data validation will be handled by developers. But In FastAPI there is inbuilt data validation (pydantic). So it will raise an error when it gets an invalid data type from the user. This is useful for developers to interact with the API endpoints.

Documentation:

Flask doesn’t have any inbuilt documentation for swagger UI. We need to add some extensions like Flassger and Flask-RESTEX and some dependency setups. But In FastAPI it generates an automatic swagger UI when the API is created. For accessing the auto-generated swagger UI hit the endpoint with /docs or /redoc. It will show all the endpoints in your application.

HTTP METHODS:

Flask	FastAPI
@app.route("/get", methods= ['GET'])	@app.get('/get', tags=['sample'])

Production Server

At some point, you’ll want to deploy your application and show it to the world.

Flask

Flask makes advantage of WSGI, which stands for Web Server Gateway Interface. The disadvantage is that it is synchronous. This means that if you have a large number of requests, they will have to wait in line for the queue to finish.

FastAPI

FastAPI is an ASGI (Asynchronous Server Gateway Interface), web server, which is lightning fast because it is Asynchronous. So, if you have a lot of requests, they don't have to wait for the others to finish before being processed.

Asynchronous Tasks

Flask

In Flask Async can be performed by thread or multiprocessing or use some tools like celery, Create await/async for handling routes

Installations

Example:

FastAPI:

In FastAPI there is a default AsyncIO. So we can simply add the async keyword before the function.

FastAPI was Built with Primary concerns

Speed and Developer Experience
Open Standards.

FastAPI can connect Starlette, Pydantic, OpenAPI, and JSON Schema.
FastAPI uses Pydantic for data validation and Starlette for tooling making it twice as fast as Flask and equivalent to high-speed web APIs written in Node or Go.
Starlette + Uvicorn supports async requests, while Flask does not.
Data validation, serialization and deserialization (for API development), and automatic documentation are all included (via JSON Schema and OpenAPI).

Which Framework is Best for AI/ML

Both Flask and FastAPI are the popular Framework for developing Machine learning and web applications. But most data scientists and Machine learning developers prefer Flask. Flask is the primary choice of Machine learning developers for writing the API’s . A few disadvantages of using Flask is time consuming for running the big applications. The major disadvantage in flask is to add more dependencies by adding plugins and the other one is lack of Async support whereas FastAPI supports Async by default . FastAPI is used for the creation of ML instances and applications. In the machine learning community Flask is one of the popular frameworks.Flask is perfect for ML engineers who want to create web models. FastAPI, on the other hand, is the best bet for a framework that provides both speed and scalability.

Migrating Flask TO FastAPI :

Yes, It is possible to migrate a Flask application to FastAPI. In FastAPI there is native async support. Flask also supports Async but is not as extensive as FastAPI. There is some syntactical difference between Flask and FastAPI.

The Application object in Flask and FastAPI is

Simple Example for Migrate Flask to FastAPI:

Flask Application

1.To Migrate the Flask to FastAPI we need to install and import libraries.

2. URL Parameters (/basic_api/employees/)

In FastAPI the request methods are defined in the methods FastAPI objects. For Example @app.get, @app.post, @app.put.

The Request Methods in Flask and FastAPI is

Here in the put request route, we are passing a body as an Employee object. And also we will create a new class called Employee and inherit it from the base model. And pass the type of the URL parameter employee_id within the route, instead of that pass the type of the parameter in employee_get()

Query Parameters:

Like URL Parameters, Query parameters are also used for managing the state(For sorting or Filtering).

Flask

FastAPI

Run the server in Flask And FastAPI

Main (Flask)

Main (FastAPI)

And Finally the FastAPI Application looks like :

FastAPI Application

Use ASGI Application web server Uvicorn to run the FastAPI application (uvicorn.run(app)).

When Should you choose FastAPI instead of Flask and Django?

Native Async Support:The FastAPI web framework was created using the ASGI web server. Native asynchronous support eliminates inference latency.
Improved latency: As a high-performance framework, the framework's total latency is lower when compared to Flask and Django.
Production-ready:With the FastAPI web framework's auto validation and short defaults, developers may easily design web apps without rewriting the code.
High Performance: Developers have access to the key functionalities of Starlette and Pydantic because they are compatible. Needless to say, Pydantic is one of the quickest libraries, and as a result, overall speed improves, making FastAPI the preferred library for web development.
Learn Simple:This is a minimalist framework so it is easy to understand and learn.

Flask Or FastAPI: Which is better

S.No	Flask	FastAPI
1.	Flask is a micro web framework to develop small-scale web applications and Rest API. Flask is depends on WSGI toolkit (werkzeug, Jinja2)	FastAPI is considered one of the Fastest frameworks compared to the flask. FastAPI is built in Pydantic and starlette.
2.	Flask is built in Web Server Gateway Interface(WSGI)	FastAPI is built in Asynchronous Server Gateway Interface(ASGI)
3.	It does not have any inbuilt documentation such as swagger UI and needs to add some extensions like Flasgger or Flask RESTX.	In FastAPI it has inbuilt documentation like (docs and redocs).
4.	There is no Inbuilt data validation in Flask, we need to define the data type in requests.	In FastApI there is an Inbuilt data validation that will raise the error if the user provides an invalid data type.
5.	Flask is more flexible than Other frameworks.	FastAPI is flexible in code standards and it does not restrict the code layouts.

Conclusion:

After learning about both Flask and FastAPI. Both are used to create a Web application and Rest API. But FastAPI is better when compared with Flask. Because FastAPI has a native ASGI support (Asynchronous Server Gateway Interface). So it is Faster and High in performance. Also, it has inbuilt documentation(Swagger UI) and data validation. FastAPI has High and Fast performance, Efficiency and it's easy to understand and learn. When compared to Flask, FastAPI has less community support but it reaches a lot in a short period of time.

11 essentials devops metrics to boost productivity

As businesses continue to grow and demand more from their technology departments, DevOps has emerged as a key contributor to increased productivity.

As businesses continue to grow and demand more from their technology departments, DevOps has emerged as a key contributor to increased productivity. When some say it's about new tools, some claim it’s a change in culture, while others associate it with the engineer role, DevOps is the idea of functionality and operability together. By integrating DevOps practices into an organization's overall IT strategy, businesses can achieve efficiencies in both the development and deployment stages of software projects, leading to a more streamlined and efficient process. The very interesting thing about DevOps is that while frequently, its mission is to create a change in the culture of an organization, this change requires far more than coordination: it also requires pure collaboration and co-laboring. You’ll see this same principle of empathy at work within your company or in your own team which boosts productivity. It is a way of working that allows teams to manage software development and IT operations together. This helps to increase the efficiency of the organization, while also reducing the risk of defects.

The technology landscape is always evolving, whether it is through new infrastructure, or a new CO tool coming out to help you manage your fleet better

—Mike Kail

How does DevOps work?

DevOps is one of the most important concepts in modern software development. It's a collaboration method that encourages communication and cooperation between developers, operations staff, and testers. DevOps helps to speed up the process of creating and deploying software by automating many of the manual tasks while enhancing the problem-solving aspect all on its own. Cloud computing being centralized offers standard strategies for deployment, testing, and dynamic integration of the produced collaboration. It’s a survival skill of adapting according to the ever-changing and demanding market requirements.

TIP

DevOps helps you manage things effectively so that teams can spend more time on research, development, and betterment of the product.

Metrics for DevOps are crucial for optimizing and establishing a higher-quality software development process.

Here are 11 essential DevOps metrics to increase productivity in organizations:

Frequency of deployment

It is vital to promote and sustain an ambitious edge by providing updates, new functions, and enhancements to the product's quality and technological efficiency. Increased delivery intensity enables greater adaptability and compliance with changing client obligations. The objective should be to enable smaller deployments as frequently as possible. Software testing and deployment are significantly more comfortable with smaller deployments.

TIP

Organizations can use platforms such as Jenkins to automate the deployment sequence from staging to production. Continuous deployment ensures that the code is automatically sent to the production environment after passing all of the test cases in the QA environment.

Time required for deployment

This indicator indicates how long it will take to accomplish a deployment. While deployment time may look trivial at first glance, it is one of the DevOps indicators that indicates possible difficulties. If deployment takes hours, for example, there must be an issue. As a result, concentrating on smaller but more regular deployments is beneficial.

Size of the deployment

This measure is used to monitor the number of feature requests, and bug patches sent to production. The number of individual task items varies significantly depending on their size. Additionally, you can keep track of the number of milestones and other parameters for deployment

Enhance Customer satisfaction

A positive customer experience is important to the longevity of a product. Increased sales volumes are the outcome of happy customers and excellent customer service. As a result, customer tickets represent customer satisfaction, which then reflects the DevOps process quality. The fewer the numbers, the higher the quality of service.

Minimize defect escape rate

Are you aware of the number of software defects detected in production versus QA? To ship code rapidly, you must have confidence in your ability to spot software defects before they reach production. Your defect escape rate is a good DevOps statistic for monitoring the frequency with which those defects make their way into production.

Understanding cost breakups

While the cloud is an excellent approach to reducing infrastructure expenses, certain unplanned failures and incidents can be rather costly. As a result, you should prioritize collecting and decreasing unnecessary costs. DevOps plays a major role here. Understanding your spending sources might assist you in determining which behaviors are the most expensive.

Reduce frequent deployment failures

We hope this never occurs, but how frequently do your releases result in outages or other severe issues for your users? While you never want to undo a failed deployment, you should always plan for the possibility. If you are experiencing troubles with failed deployments, monitor this indicator over time.

Time required for detection

While minimizing or even eliminating failed changes is the optimal strategy, recognizing errors as they occur is crucial. The time required to discover the fault will affect the appropriateness of existing response actions. Protracted detection times may impose limits on the entire operation. Establishing effective application monitoring enables a more complete picture of "detection time."

Error Levels

It is vital to monitor the application's error rate. They serve as a measure not only of quality difficulties but also of continuing efficiency and uptime issues. For excellent software to exist, the best methods for handling exceptions are necessary.

TIP

Track down and record new exceptions thrown in your code that occur as a result of a deployment.

Application Utilization & Traffic

You may wish to verify that the quantity of transactions or users logging into your system seems to be normal post-deployment. If there is a sudden lack of traffic or a big increase in traffic, something may be amiss. Numerous monitoring technologies are available to provide this data.

Performance of the application

Before launching, check for performance concerns, unknown defects, and other issues. Additionally, you should see changes in the overall output of the program both during and after deployment. To detect changes in the usage of particular queries, web server operations, and other requirements following a release utilize monitoring tools that accurately reflect the changes.

In conclusion, DevOps is a process that can be used to increase productivity in an organization. By using DevOps, an organization can improve communication between development and operations teams, optimize workflows, and track key metrics that can be used to improve the overall process. By following these 11 essential DevOps metrics, an organization can see an increase in overall productivity. The metrics stated above will help you figure out what to track and improve. Get in touch with us to take your DevOps journey to the next level.

Prometheus vs Influxdb : Monitoring Tool Comparison

When it comes to data storage, there are few alternatives that can compete with the venerable Prometheus, such as InfluxDB. But what if you need more than just collected data? What if you need real-time insights into your systems? Another powerful platform for real-time data analytics and storage is InfluxDB. Let's compare how they fare with one another.

Prometheus is a memory-efficient, quick, and simple infrastructure monitoring system. InfluxDB, on the other hand, is a distributed time-series database used to gather information from various system nodes. In this article, we are going to compare Prometheus and InfluxDB. Both systems have their strengths and weaknesses, but they are both effective monitoring tools. If you are looking for a system that can monitor your database servers, then Prometheus is a good option. If you are looking for a system that can monitor your entire infrastructure, then InfluxDB is a better choice.

What exactly is Prometheus?

Prometheus is a time-series database and monitoring tool that is open source. Prometheus gives its users sophisticated query languages, storage, and visualization tools. It also includes several client libraries for easy interaction. Prometheus can also work with various systems (for example, Docker, StatsD, MySQL, Consul, etc.)

TIPS

Prometheus can be great for monitoring as long as the environment does not exceed 1000 nodes. Prometheus + Grafana = best ecosystem

What is InfluxDB?

By InfluxData, Inc., a database management system called InfluxDB was created. InfluxDB is open-source and cost-free to use. The InfluxDB Enterprise version is installed on a server inside a corporate network and comes with maintenance contracts and unique access controls for business customers. A web-based user interface for data ingestion and visualization is also included in the new InfluxDB 2.0 version, which operates as a cloud service that is fully customizable.

TIPS

When it comes to storing monitoring metrics, InfluxDB excels (e.g. performance data). If you need to store different sorts of data, InfluxDB is not the best option (like plain text, data relations, etc.)

Let's see how these differ from one another

Features	Prometheus	InfluxDB
Data Gathering	Prometheus is a system that operates on the principle of pull. The metrics are published by an application at a certain endpoint and Prometheus retrieves them on a regular basis.	The system InfluxDB is based on is a push-based system. It requires an application to push data into InfluxDB on a regular basis.
Storage	Prometheus and InfluxDB both follow the key/value datastores. However, these are executed very differently on the two systems. Each metric in Prometheus is kept in its own file and is stored in indices that use LevelDB. Metrics recording and monitoring based on those are the major uses of Prometheus.	Both the indices and the metric values are stored in monolithic databases by InfluxDB. Compared to Prometheus, InfluxDB often uses more disc space. The best database for event logging is InfluxDB. So we have a choice based on the requirements.
Extensibility and Plug-ins	Prometheus’ key benefit is its widespread community support, which stems from its CNCF-accredited project status. Many apps, particularly cloud-native applications, already support Prometheus.	While InfluxDB has a lot of integrations, it doesn’t possess as many as Prometheus.
Case Studies	Prometheus was designed for monitoring, specifically distributed, cloud-native monitoring. It shines in this category, with several beneficial integrations with current products.	While InfluxDB can support monitoring, it is not as well known as Prometheus for this purpose. As a result, you may have to develop your own integrations. If you want to do more than a mere monitoring tool, InfluxDB is a fantastic solution for storing time-series data, such as data from sensor networks or data used in real-time analytics.
Query language	Prometheus uses PromQL, a language that is much easier and has no connection to conventional SQL syntax. Let's say we want a number for CPU load that is greater than 0.5. In that case, we can simply enter CPU load>0.5 in the Prometheus command prompt.	For its querying purposes, InfluxDB uses a standard SQL syntax known as InfluxQL. For instance, we could write select * from tbl where CPU load>0.5 in the Prometheus cell. This seems simple to an associate with a background in SQL, but Prometheus is also not a challenging experience.
Community	Prometheus is an open-source project with a huge community of users that can rapidly resolve your queries. Having a big network of support is an added benefit since there is a high probability that the challenges one is having might previously have been encountered by someone in the community.	InfluxDB, despite its popularity, needs to improve on community support in comparison to Prometheus.
Scaling	When the load rises, the monitoring Prometheus servers require scaling as well.This is due to the fact that the Prometheus server is independent. Thus, the Prometheus server works great for the simpler load.	Since the commercial section of Influx DB is distributed, there will be many interconnected nodes. As a result, as the server scales up, we don’t have to worry about scaling nodes. Thus, Influxdb nodes might be considered redundant while handling complicated loads.

TIPS

InfluxDB performs exceptionally well at storing monitoring metrics (e.g., performance data). Compared to Prometheus, InfluxDB utilizes more disc space and has a monolithic data storage strategy. It performs well for recording occurrences.

Conclusion

As a result, you can consider the factors discussed in this article while choosing between Prometheus and InfluxDB as monitoring systems for time series data, depending on your business case. When it regards monitoring services for time series data, both platforms are extremely well-liked by enterprises. Some claim that PromQL is new and InfluxQL is similar to SQL and will thus be better, but the reality is different. PromQL is considerably more user-friendly for querying, so go for it. Prometheus has a lot more functionality and integrations, so you can choose it. InfluxDB is a better option if you're looking for something specifically for IoT, sensors, and other analytics.

Remote Monitoring by Doctors

Communication between Doctor and patient is very important for recovery of a patient. With the help of remote monitoring devices, patients need not travel back and forth between their house and hospital

Introduction

Communication between Doctor and patient is very important for the recovery of a patient. Remote monitoring devices avoids the back and forth travel of patients between hospital and their house. Their health condition can be regularly monitored by using remote devices and hospitalization of the patient can be prevented. Remote patient monitoring is shortly abbreviated as RPM and is a method of capturing patient’s health data. It captures all vital information of a patient such as BP, Sugar level, heart rate, etc. Remote monitoring has proved to be advantageous by reducing patient readmission and allow treatment sooner

Overview of market share

The global remote patient monitoring market is projected to reach USD 117.1 billion by 2025 from USD 23.2 billion in 2020, at a CAGR of 38.2% between 2020 and 2025. The factors that boost the demand for remote patient monitoring are a reduction in the number of health care staff and an increase in awareness of telemedicine. There is a growth in the market due to the efforts taken for the discovery of Innovative devices Patient remote monitoring is becoming a sturdy market

How remote monitoring Works

Even while at home patients can carry out their normal activities and monitor their health. The remote monitoring devices helps them to monitor their health and collect data These monitoring devices are integrated with patient monitoring apps. The apps transmits the data electronically to their Doctor Doctors then examine this patient data from a distance. In case of a patient who needs immediate treatment or attention, alerts are sent to the patient’s mobile and they receive it in the form of notifications. This remote monitoring technology helps to detect any issue at an earlier stage

What are the best features to have in remote patient monitoring apps

Some of the best to have features of remote patient monitoring apps

Notifications

Timely notification is an important feature of remote patient monitoring. Timely notification may prevent them from a serious illness. Also, notifications should be in sync for both patient and doctor

Integration with devices

Integrating with monitoring devices is an important feature. When integrated, the app will be able to collect data from these devices from time to time which might help to monitor progress over a period of time

HIPAA Compliance

Patient data is highly sensitive and it needs to be protected. It should be ensured that it meets HIPAA compliance Remote monitoring apps should have physical, network, and process security measures to ensure HIPAA compliance

Support for BLE

Remote monitoring apps need to support Bluetooth connectivity which is very essential for the transfer of data between monitoring devices and apps

Integration with doctor’s system

Integration with a Doctor’s system through secure API built on FHIR industry standard to ensure proper exchange of data between multiple systems is an important feature that needs to be handled

Tech Stack

Blockchain

The patient and Doctor are connected through voice and video calls. Encryption of patient data prior to transmission is very important. Blockchain technology is used for encrypting the sensitive patient data

Cloud Storage

Cloud services are used for storage of data as it improves privacy and security control of the app. Also, data retrieval is very quick from the cloud servers. So storage and transfer become efficient

How to work with offshore teams and manage remote offshore teams successfully?

Working with offshore teams is a common practice in the IT industry. Web and mobile app development are among the most common tasks that are outsourced to offshore development teams

Introduction

Working with offshore teams is a common practice in the IT industry. Web and mobile app development are among the most common tasks that are outsourced to offshore development teams. Outsourcing to an offshore team allows you to hire expert professionals for a fraction of the price that you would have to pay if you would hire full-time in-house employees. Along with salary of the employee, other expenses like health insurance, insurance contribution, and bonuses can also be saved. You are not required to spend money on office space, IT infrastructure, and utilities such as electricity. Moreover, a business can easily decrease or increase the size of the team according to its requirements. Thus, businesses enjoy both flexibility and scalability by outsourcing their projects to offshore teams

Overview of Offshore Teams

An offshore team usually implies a certain number of specialists who work for you remotely. They can be located at any place and the communication is done through phone calls, messengers like slack or video calls through zoom, meet. Hiring remote developers can be of great help financially. It helps to save cost. Such practice was usually associated with small companies that had a lack of financing. However, today the situation is different and even huge companies turn offshore as it has a number of undeniable benefits

Here are 5 reasons why businesses hire offshore teams:

Controlled Costs
Drastically Improved Efficiency
Focus on Overlooked Areas
Access to a Global Talent
Flexibility

Handling the Common Challenges in Offshore Team Management

Here are the most common challenges that clients come across while handing their offshore teams

Communication Challenges

There are two things that can make or break the whole project: time-zone difference and language skills of an offshore vendor. The time zone difference creates difficulty in communicating with an outsourced team. So the calls are postponed which in turn lowers productivity and causes delay in project delivery How to overcome the challenge - There might be few hours overlap in time zone. This overlap can be used effectively for various activities like feedback, checking project progress and for communicating with the remote team When all the expectations are set up front, it becomes much easier to achieve them, as well as monitor the development process. The outsourced team has to clearly understand what is expected from them and what the requirements for the future product are

Lack of Control

For some managers, it is very crucial to be in charge of each step on the development timeline– So working with an independent vendor is not a comfortable experience. Not being able to ensure the project progresses according to plan is one of the challenges that come with outsourcing How to overcome the challenge - To know how to manage a remote development team, a business manager can send a trusted employee to work at the dedicated office and oversee project development. Asking for a personal account manager who keeps tabs on the product’s progress is another way to get more control over the development

Ineffective Project Management

what’s happening at each stage of development, are the red signs that something is wrong. If you came across these offshore team challenges, it can either mean that the vendor is incompetent or aren't following the methods that you use in your work How to overcome the challenges – The outsourced team should understand clearly and follow the development methodology a project needs. Make sure that the outsourcing company does have access to the technologies or tools needed for the completion of the project

How to Get Maximum Productivity from an Offshore Team

Daily Meetups

Communication is the key to development success. That goes for any kind of group effort, and doubly so when the people are geographically disparate. When your team is far away from you, it should be ensured that you are updated about the progress of work. For updates about the progress of work, project management models like Scrum, Kanban or Agile can be used. To make the most out of it, use one of the project management models (Scrum, Kanban, Agile, etc.) while working with the outsourcing agency. By ensuring that your people all talk to each other daily, you’re keeping information flowing. Everyone knows what’s being worked on, and what their part is

Sprint Planning

Despite the daily stand-up, everyone is going to be largely working on their own tasks, and there’s a real danger of people’s work getting in each other’s way. The planning meeting is when those tasks are explained and handed out. If you’re following Agile (which you should), then you’ll have a scrum master and a product owner both participating to ensure that everyone comes out of the meeting knowing exactly what to do and why. As for the length of the sprint, that’s up to you

Discuss Your Project Goals

Just assigning a project to an offshore team without letting them know the goal behind it can land you in trouble. The developed product may not be as you expected it to be. Offshore developers require full product vision before starting working on the project. They should be given complete details like why the product is required, what functions will be carried out by the product, what all specifications is required in the product, and when it is expected to be

Make Use of Agile Methodology

As software development is a process that requires a high level of interaction and iteration, the adoption of agile methodology for offshore teams helps in the development and delivery of a high-quality software product on time In some cases a sprint may be just one weeks’ time or it may be one or two months. Based on priority, features can be allocated to different sprints. At the beginning of each sprint, you and your offshore team can have a discussion regarding the features to be developed and create a detailed plan. Whenever required face to face communication can be initiated with your remote team.

Communicate Frequently and Use Simple Language

When working with your remote team, you can communicate very easily and frequently by initiating face-to-face talk whenever you require. With offshore teams, you should communicate even more frequently so that all the things are clear and there is no confusion despite the large distance between your in-house and offshore teams

Communicating with Offshore Teams

Here are some highly recommendable communication tools that help you when you are working with remote teams

JIRA

This includes everything from planning till analytics. It allows to set clear and actionable goals. Their progress can be easily tracked. Jira is customizable and it is capable of working equally good for all of the Agile methodologies

How To Effectively Use Istio For Enterprise Governance and Monitoring

The client offers deep and contextual application-layer visibility to remove the blind spots within distributed and cloud-native application environments, in a completely frictionless

Introduction

The client offers deep and contextual application-layer visibility to remove the blind spots within distributed and cloud-native application environments, in a completely frictionless manner while being agnostic to the platform, cloud, environment, and workload type. The solution allows many people like cloud application practitioners, security leaders, and application owners to have a visibility which would help them to address compliance, and security controls for microservices and other distributed applications

Overview of Challenges faced by Client

The client has run their pre-production application in cloud infrastructure and it costs high
The client engineering team spent most of their time deploying their changes on cloud infrastructure for evaluation
The client team faced more challenges in deploying their application in cloud environments and that cost 45% of their monthly budget allocation.
Client teams spend more time on deployment and testing in cloud infrastructure will extend the delivery time of the application

How Current system Works

Enterprises today deploy perimeter-centric solutions, such as network firewalls, web application firewalls, and/or API Gateways. Others like container firewalls, network-layer micro-segmentation, or manual application testing are also tried. Some other solutions concentrate on one type of workload (e.g. containers) or are focused on data-in-use or data-at-rest and do little to secure against run-time attacks embedded deep within the application-layer components

How we proposed system architecture

The client ideally needs an Infrastructure with different topologies of system types templated as a solution.Generic engine for generation and regeneration of infrastructures need to be utilized. Following are some of the key considerations

The solution proposed is to create an environment like cloud infrastructure in local machines
Writing tests framework to make the client engineering team use for their Unit Testing
We are using MetalLB for implementing network Load Balancer in K8 local infrastructure
Implementation of microservices to simplify the deployment and improve the performance of the application. By using testing frameworks to deliver the flawless application in a production environment
Containerize the microservice components to achieve the CI/CD process with the K8 cluster to reduce the time spent for on deployment
Provide scripts to automate the process of testing and deliver the application with zero bugs

What are the Benefits of the proposed system?

1. DevOps process will reduce the deployment and testing time
2. The product has been cleverly architected to ensure zero latency to the application, while still providing all the security features and benefits
3. Provides a vulnerability assessment of the application components and provides recommendations on how to make them more secure
4. Reduced the cloud Infrastructure cost up to 45%

What Are The Phases of Software Development Lifecycle

Software Development Lifecycle, in short, termed as SDLC is a process that defines various stages involved in software development for the delivery of a product.

Software Development Lifecycle, in short, termed as SDLC is a process that defines various stages involved in software development for the delivery of a product. SDLC is very important as it gives a framework for a set of activities and ensures the quality of the product delivered. There are seven phases involved in Software Development Lifecycle. They are Planning, Requirement Analysis, Design, Implementation, Testing, Deployment, and Maintenance. Here we shall see each of these phase-in detail

Phases of SDLC

1. Planning

As the quote says “By failing to prepare, you are preparing to fail”, Planning is very important for any task. Similarly, Planning is the initial phase of the Software Development Life cycle. Planning starts with listing the problems of an Existing system. Problems in the existing system are listed to come up with the objectives of the new system to be developed. Along with the scope of the new system, financial planning and Resources planning are also done in this phase. Then last comes the planning for the project schedule which is very essential to complete the project on time. Only when the planning phase is completed, it can be moved on to the other phases

2. Requirement Gathering and Analysis

Defining Requirements and gathering all required information like the purpose of the new system, end-users for the new system, their needs are all carried out during this phase. Risks involved in the development of the new system are also identified. The analysis is done to ensure that the end-users needs can be met by the new system. All clarifications regarding the requirements are received from the concerned team before starting on the Design part. The output of this phase will be in the form of a document more often called a Software Requirement Specification or SRS document. This document along with new system requirements also contains Software, Hardware, and Network requirements needed for the development of the new system. This will be used as the input for the design phase

3. Design

Design is a kind of modeling everything visually. Developers will outline the details for the new system using the Software Requirement Specification document in the form of a Design Document. The Design document will include details like User Interface which will define how the user is going to interact with the new system, Database which is going to be used for storing data, platforms on which the new system will run, Security measures to be taken to protect the system, etc. So both front-end and back-end are defined here. If required, prototypes are also defined. Prototypes give a basic idea of the actual look and feel of the new system. When the design is completed it is time to move on to the next phase, which is the development phase

4. Development

This phase is the coding phase. This is the most important phase of SDLC as it is where the actual software is developed. It is the longest phase of SDLC. Here the design document is converted into the software. The developers need to make sure the software meets the Software requirement specifications. Developers will have to follow coding standards and use tools like compilers and debuggers to eliminate coding defects. Identifying coding bugs and fixing them is critical here. Programming languages are chosen based on the requirements and specifications of the project. A detailed design will help in hassle-free code development

5. Testing

Testing of an application is critical before it is actually made available to the Users. This is part of a Quality Assurance process. It is started as soon as coding is completed and all coding errors are fixed. It is done by Quality Assurance Engineers. Manual or Automated Testing are performed depending on the Project. In the case of Automated Testing, many tools are available in the market. Again depending on the nature of the project automated testing tools are selected. The developed software is tested thoroughly to make sure that the requirements are met. The defects are identified and logged in Defect Tracking tools. Then they are tracked to closure. Different types of defect tracking tools are used by different companies. The initial testing done is called Unit testing. Then the individual units are integrated and integration testing is performed. The software is repeatedly tested to ensure that there are no more defects

6. Deployment

When the defects are all closed and no more defects are identified, the software is ready for installation. The installation phase is often called the Deployment phase. In some cases, it could be the deployment of code on a web server, and in some cases, it could be integrating with other systems. The users can start using the software after deployment. In some cases, since the software is deployed to the production environment, again another round of testing is carried out here to ensure that there are no issues in the new environment. The users could also be trained just before this phase to make sure that they are aware of the usage and features of the new system

7. Maintenance

Maintenance is an important phase as there might be issues identified when the end-users start using the product. In some cases, the end-users keep changing and there might be different types of issues identified. These issues need to be fixed from time to time. The maintenance time might vary depending on the size of the project. Sometimes even new features are added as per user feedback and released

SDLC Models

There are various SDLC models and the most common ones are Waterfall and Agile. We shall see about these in detail

Waterfall Model

This was the most commonly used and most accepted model. The output of one phase of the Software Development Lifecycle is used as the input for the next phase. So the successive phases can be started only after the completion of the previous phase. At the end of each phase review and sign-off is done before moving on to the next phase. The waterfall model is very useful when the requirements are fixed and do not keep changing. The main advantage of the waterfall model is it is easy to follow and the milestones are clearly defined

Agile Model

Agile is a simple and highly effective process. In the Agile model, the task is divided into small iterations of smaller durations. For each iteration, all phases of SDLC like planning, analysis, design, coding, implementation, testing, and deployment are carried out. Here there will be continuous delivery. Even when there are frequent changes in the requirement that can be handled here easily. During each sprint the new requirements come from Backlog and roll through all phases of SDLC. Since changes are inevitable the agile model helps the project to adapt to it instead of ignoring it SDLC is a systematic process and it ensures the quality of the product delivered. All phases of SDLC are very important. So adhering to phases of SDLC is very important for the success of the project

How to build a Ridesharing App?

The main idea of taxi booking apps is to book a taxi in under 30 seconds easily. And the most convenient way is to connect drivers and riders via a mobile app like Uber, Ola, etc.

You can call your trip in the following criteria

The passenger has pre-planned a trip and his travel
The passenger has made no prior arrangement and this is unplanned
The passenger is out on the road and looking for a taxi service

Sometimes passengers may look for companions to share costs but have a rest during long trips The main idea of taxi booking apps is to easily book a taxi in under 30 seconds. Like Uber and Ola it would be easy and convenient for a rider to connect with a driver through a mobile app.

Here’s how Taxi Booking Apps work

Request - Passengers specify where they’re going, where they'd like to pick up and drop off passengers, and when
Booking - Passengers look through the type of trips, cars, and book a ride
Payment - Passengers pay in the app or cash when they get in the car
Rating - Riders rate the trip and leave their reviews

If riders choose to pay via the app, the money goes to the drivers bank account from the time of payment within two days

Must-Have Features

Registration & Profile

For registration the user need to enter his phone number, email and then generate a password. Some apps also offer signing up through social media like facebook, Google or twitter and helps to save the time of user.

Book a Ride

Initially passengers enter their destination along with pickup point and then select a driver to take up the ride. Before starting a ride the rider will look for the cost. Drivers can view the booking requests and accept or reject them. Otherwise they can accept all requests that come to them automatically. When there is no ride available for a rider, he will get an alert saying that he will be notified as soon as a ride is available.

My Rides (Passenger/Driver)

Passengers see the number of rides they’ve completed and their details—date, destination, car, payment details—in the ‘archived’ tab

GPS Location

In ride-sharing app development, GPS is used to detect someone's location. That's how drivers can set exact pickup and drop off points, while riders can see their whole route

Fare Calculation

The app calculates the cost for each passenger based on their number and travel distance. This helps passengers to select the preferred mode of payment.

Online - The app transfers money to PayPal or a bank account
In cash - Riders pay in the car before or after the ride

Admin Panel

Admin panel helps the administrators to manage users. They can search for an user, block them or check up an ID card, do payments, perform reviews, generate reports or view statistics

How to Monetize a Taxi Booking App?

Before you start creating a ridesharing app the first step would be to choose a monetization model. The most common are

Paid advertising (users see third-party ads in the app)
Reservation/cancellation fees for riders (passengers pay a small booking fee to confirm their intentions)
Transaction fees for drivers
Collecting a small service fee for every ride from passengers

Cloud Migration : Lift & Shift Strategy

Lift-and-shift is the process of migrating a workload from on premise to Cloud with little or no modification

Introduction

Lift-and-shift is the process of migrating a workload from on-premise to Cloud with little or no modification. A lift-and-shift is a common route for enterprises to move to the cloud and can be a transitionary state to a more cloud-native approach

There are also some workloads that simply can’t be refactored because they’re third-party software or it’s not a business priority to do a total rewrite. Simply shifting to the cloud is the end of the line for these workloads

Applications are expertly “lifted” from the present environment and “shifted” just as it is to new hosting premises, which means in the cloud. There are often no severe alterations to make in the data flow, application architecture, or authentication mechanisms

It allows your business to modernize its IT infrastructure for improved performance and resiliency at a fraction of the cost of other methods

Overview of Market Share

In recent days there is great growth in Cloud computing market. Companies are trying out various cloud models with right balance of flexibility and functionality The cloud migrations hosts the application and data in an effective environment based on various factors. This is the key role of cloud migration Many companies migrate their on-site data and application from their data center to cloud infrastructure with the benefits of redundancy, elasticity, self-service provisioning and flexible pay per use model. These factors are further expected to drive tremendous growth in the global cloud migration services market during the forecast period 2020-2027 According to the report, the global cloud migration services market generated $88.46 billion in 2019 and is estimated to reach $515.83 billion by 2027, witnessing a CAGR of 24.8% from 2020 to 2027 The growth of the market is attributed to an increase in cloud computation among small and medium enterprises around the globe

What are the best features to have?

Workloads that demand specialized hardware, say, for example, graphical cards or HPC, can be directly moved to specialized VMs in the cloud, which will provide similar capabilities
A lift and shift allows you to migrate your on-premises identity services components such as Active Directory to the cloud along with the application
Security and compliance management in a lift and shift cloud migration is relatively simple as you can translate the requirements to controls that should be implemented against compute, storage, and network resources
The lift and shift approach uses the same architecture constructs even after the migration to the cloud takes place. That means there are no significant changes required in terms of the business processes associated with the application as well as monitoring and management interfaces
It is the fastest way to shift work systems and applications on the public cloud because there isn’t a need for code tweaks or optimization right away
Considered the most cost-effective model, the lift and shift help save migration costs as there isn’t any need for configuration or code tweaks. In the long run, these savings could give way to extra spending if workload costs are not optimized
With minimal planning required, the lift and shift model needs the least amount of resources and strategy
Posing the least risk, the lift and shift model is a safe option as compared to refactoring applications especially in the scenario where you don’t have code updating resources

When is the Lift-and-Shift Cloud-Migration Model the best fit? The lift and shift approach allows on-site applications to be moved to the cloud without any significant redesigns or overhauls. You should consider using the lift and shift approach if the following apply to your business You’re on a deadline If you’re in a time crunch, the lift and shift approach may help expedite the transition to the cloud quicker than other methods You want lower costs A lift and shift migration can provide cost savings compared to more expensive methods such as re-platforming and refactoring. This approach is of minimal risk and is beneficial for workplace operations You want to reduce risk Lift and shift approach is less risky and simpler process when compared to other methods like refactoring or re-platforming When you are choosing options to migrate, you need to look at the larger picture Although the lift and shift technique can work well in many instances, you should consider all options and choose the migration type that will keep you functioning at peak performance By choosing the right IT support firm to assist with the transition, you can mitigate cloud migration challenges to ensure optimal performance and a seamless transition With the lift-and-shift method, on-premise applications can move to the cloud without remodeling. Since they cannot take full advantage of native-cloud features every time, this may not be the most cost-effective migration path Bounce back can be avoided by developing a strategy for cost-allocation and defining roles to monitor how much is spent for cloud

Cloud Migration Steps: Ensuring a Smooth Transition

First, choose which platform that you wish to migrate to
Examine all the connections in and out of the application and its data
If you are lifting and shifting more than one application, then you may need to consider automating multiple migrations
You should consider containerization to replicate the existing software configurations. This will also allow you to test configurations in the cloud before moving to production
Back up the databases from the existing system as well as supporting files. When the new database is ready, restore the backups
Once migrated, test the application
Check that all the current data compliance and regulatory requirements are running in the new cloud deployment. Run your normal validation tests against the newly migrated application
Don’t be tempted to introduce new features during the migration. This can lead to many hours of additional testing to make sure you have not created new bugs
Retire your old systems once testing is complete

Prometheus vs Influxdb : Monitoring Tool Comparison

What exactly is Prometheus?

TIPS

Prometheus can be great for monitoring as long as the environment does not exceed 1000 nodes. Prometheus + Grafana = best ecosystem

What is InfluxDB?

TIPS

Let's see how these differ from one another

Features	Prometheus	InfluxDB
Data Gathering	Prometheus is a system that operates on the principle of pull. The metrics are published by an application at a certain endpoint and Prometheus retrieves them on a regular basis.	The system InfluxDB is based on is a push-based system. It requires an application to push data into InfluxDB on a regular basis.
Storage	Prometheus and InfluxDB both follow the key/value datastores. However, these are executed very differently on the two systems. Each metric in Prometheus is kept in its own file and is stored in indices that use LevelDB. Metrics recording and monitoring based on those are the major uses of Prometheus.	Both the indices and the metric values are stored in monolithic databases by InfluxDB. Compared to Prometheus, InfluxDB often uses more disc space. The best database for event logging is InfluxDB. So we have a choice based on the requirements.
Extensibility and Plug-ins	Prometheus’ key benefit is its widespread community support, which stems from its CNCF-accredited project status. Many apps, particularly cloud-native applications, already support Prometheus.	While InfluxDB has a lot of integrations, it doesn’t possess as many as Prometheus.
Case Studies	Prometheus was designed for monitoring, specifically distributed, cloud-native monitoring. It shines in this category, with several beneficial integrations with current products.	While InfluxDB can support monitoring, it is not as well known as Prometheus for this purpose. As a result, you may have to develop your own integrations. If you want to do more than a mere monitoring tool, InfluxDB is a fantastic solution for storing time-series data, such as data from sensor networks or data used in real-time analytics.
Query language	Prometheus uses PromQL, a language that is much easier and has no connection to conventional SQL syntax. Let's say we want a number for CPU load that is greater than 0.5. In that case, we can simply enter CPU load>0.5 in the Prometheus command prompt.	For its querying purposes, InfluxDB uses a standard SQL syntax known as InfluxQL. For instance, we could write select * from tbl where CPU load>0.5 in the Prometheus cell. This seems simple to an associate with a background in SQL, but Prometheus is also not a challenging experience.
Community	Prometheus is an open-source project with a huge community of users that can rapidly resolve your queries. Having a big network of support is an added benefit since there is a high probability that the challenges one is having might previously have been encountered by someone in the community.	InfluxDB, despite its popularity, needs to improve on community support in comparison to Prometheus.
Scaling	When the load rises, the monitoring Prometheus servers require scaling as well.This is due to the fact that the Prometheus server is independent. Thus, the Prometheus server works great for the simpler load.	Since the commercial section of Influx DB is distributed, there will be many interconnected nodes. As a result, as the server scales up, we don’t have to worry about scaling nodes. Thus, Influxdb nodes might be considered redundant while handling complicated loads.

8 Proven Ways to Reduce Your AWS EC2 Costs

AWS is everywhere and many organizations are leveraging it’s power. But with the power of AWS comes the EC2 cost which is undoubtedly a big component of your cloud payment.

It is essential to understand how to reduce AWS EC2 costs. AWS is everywhere and many organizations are leveraging its power. But with the power of AWS comes the EC2 cost which is undoubtedly a big component of your cloud payment. It’s a fact that most new startups fail to launch their business because of poor financial management. Understanding the AWS billing cycle and how it works is critical to keeping your AWS EC2 costs lowering. In this blog, you will learn about EC2 and effective methods to reduce your AWS EC2 costs without compromising your operations.

Here are 8 Proven Ways to minimize your EC2 costs:

Decide on EC2, ECS, Fargate Or Serverless Archictecture

Instances that can fulfill your applications' and workloads' needs. You can do this by evaluating your computing demands. Memory, network, SSD storage, CPU architecture, and CPU count are all factors to consider. Once you have this information, you should seek an instance that offers the greatest performance for the amount you are willing to pay. It is not hard to discover low-cost cloud instances based on your requirements. We can use serverless architecture if the REST service or deployment does not rely on the existence of running machines and can be an event driven architecture. We can also set up ECS or Fargate machines with the right size, memory, and storage to scale up or down depending on your needs.

TIPS

You can save licensing cost with predefined or bulk license management.

Leverage reserved EC2 instances

Reserved Instances are a way to buy EC2 machines for a long term and reduce overall pricing through an agreed discount. Since a reserved instance is a pre-paid model, Amazon offers a 75 percent drop on the hourly pricing per instance. As a result, the entry-level instance will cost less. The availability of the reserved instance model is likewise higher than that of the on-demand instance. Why? In a nutshell, it's because it's prepaid. As a result, it is pre-booked, allowing Amazon to schedule the time required. Finally, users can sign up for a one-year or three-year commitment to use the EC2 reserved instance.

Leverage GPU Instances

CPUs and GPUs have a significant impact on both cost and performance. You would choose which type is most suitable for your requirements. For example, if you wish to do machine learning activities on a cloud, you should use modern GPU instances such as the G3 or P3 series. Even though GPUs have a higher cost per hour, GPU instances can dramatically accelerate training time and result in cost savings (as compared to CPUs).

Spot Instances for stateless and non-production workloads

Spot instances can save a lot of money for stateless and non-production workloads. You can save up to 90% off the on-demand pricing and lower your AWS EC2 expenses. The fact that Spot Instances could be taken before the instance is used and that they are susceptible to change should be noted.

Leverage Tags & Setup Availability times

Understanding the NFR Non-functional requirements of a business can help determine the hours our EC2 machines need to run. On this basis, we can schedule the machine's startup and shutdown times and prevent unnecessary running costs and downtime for the devices. You can save money on EC2 by prioritizing some EC2 instances over others. For Example, You could restrict your search to only production, non-production, and other Instances. The AWS dashboard and the AWS API are both used to find and optimize instances using tags. Security and compliance are other possible uses for Tags.

Auto-Scaling

The Amazon Web Services (AWS) Auto Scaling mechanism ensures that the appropriate number of Amazon EC2 instances are running to meet the demand of a specific application. Auto Scaling changes compute performance dynamically based on a predetermined schedule or the current load measurements, increasing or decreasing the number of instances as necessary. To modify capacity to actual demands, you can use different types of scaling options that Amazon offers. By dynamically reducing the capacity, you can easily save money and prevent waste. Configure Auto Scaling with precision to maximize cost savings. You can over-provision capacity if you use Auto Scaling for applications that are too big or include too many instances.

EC2 Instances of appropriate size

Right-sizing is adopting an EC2 instance type that is a suitable match for your application or workloads to prevent underutilized resources. To identify the kind of instance necessary, evaluate the number of CPU and memory resources utilized by a certain application. After that, you can choose the instance type and number of instances that are most suited to your needs. By choosing your size wisely, you can gain also the most of your reserved instance purchases. Once you've determined the best configuration for your instance, you can save even more money by signing up for a specific term and obtaining reserved instances. However, it may be difficult to determine the right size when dealing with unpredictable workloads, and reserved instances are often wasted.

Orphaned Snapshots should be detected and eliminated

As per standard rules, any associated EBS volumes are automatically erased when an EC2 instance is terminated. Any snapshots that are still on S3 and are billing. These expenses might be more than you anticipate. Most backups are incremental, while the first snapshot captures the whole drive. Additionally, over time, incremental snapshots may need more data storage than the first one. Although S3 is less costly than EBS volumes, you'll need a strategy for deleting EBS volume snapshots when an EBS volume is destroyed. Over time, this might result in considerable storage cost savings.

TIPS

Always plan to set up budgets and consume resources within the budget. Custom alerts can also help us realize if we used 50%, 75% or 90% of our limit

Conclusion

The Amazon EC2 service is a great way to get some computing power without having to manage a server. However, you can't leave an instance running all day and night without paying for it. For one thing, it's not free! Common problems with EC2 costs include tracking reserved instances with unused hours, underutilized and idle EC2 instances, and migration of EC2 instances from a previous generation. Oversizing and inefficiency of the system bring their own set of challenges. Finally, there are numerous ways to lower your EC2 costs. By following the tips in this article, you can resolve the above challenges, save money and improve your efficiency.The cost of an EC2 instance is based on the instance configuration associated with data processing needs. Successfully minimizing EC2 expenses is reliant on the balance between the cloud computing needs to process corporate data and the quantity of the data that is being processed.

How to effectively use JIRA to drive the agile transformation of your organization?

Agile transformation is the sustained organization-wide process of helping individuals and organizations undergo the necessary mindset shift to reap the full benefits of agility

Introduction

Agile transformation is the sustained organization-wide process of helping individuals and organizations undergo the necessary mindset shift to reap the full benefits of agility. What makes Agile transformation necessary for the traditional business is the constant state of change as well as the democratization of value definition and delivery. By transforming the entire organization to be more Agile, big companies can retain a competitive advantage. Agile transformation is necessary for organizations to thrive in today’s markets and into the future As a leading collaboration platform for agile teams, JIRA Software boasts powerful features for marketers. JIRA is a proprietary issue tracking product, developed by Atlassian. It provides bug tracking, issue tracking, and project management functions. Also, JIRA has integrated solutions for cross-functional projects. You can easily bring all teams together to collaborate on a shared goal

Overview of Market Share

Looking at Atlassian JIRA customers by industry, Computer Software (26%) and Information Technology and Services (14%) are the largest segments. Atlassian TEAM delivered better-than-expected fourth-quarter fiscal 2021 results. The company’s non-IFRS (International Financing Reporting Standards) earnings per share of 24 cents beat the Zacks Consensus Estimate of 18 cents Atlassian forecast adjusted earnings between 38 cents and 39 cents per share on revenue between $575 million and $590 million for the first quarter. The company witnessed solid demand for its cloud-based products, primarily led by smaller customers, while the cloud migration momentum continued for larger clients Atlassian reported an operating loss of $7.5 million for the quarter, up from a loss of $3.3 million a year ago. Despite the year-over-year dollar increase, the operating margin loss remained 1%. Its shares jumped 24% to $331.96 per share Friday at the last check

How JIRA helps in the Agile Transformation of the Organization?

Creating a Scrum Project

Once you create and log in to an account in Jira Software, you can select a template from the library. Select Scrum and then, you’ll be prompted to choose a project type. If your team works independently and wants to control your own working processes and practices in a self-contained space, consider giving the team-managed Scrum template a try

Creating User Stories or Tasks in the Backlog

In Jira Software, you can create work items like user stories, tasks, and bugs "issues". Create a few user stories with the quick create option on the backlog. If you don't have user stories in mind, just create sample stories to get started and see how the process works. Once you've created a few user stories, you can start prioritizing them in the backlog. In Jira Software, you rank or prioritize your stories by dragging and dropping them in the order that they should be worked on

Creating a Sprint

Create your first sprint in the backlog so you can start planning the sprint Sprint: In Scrum, teams forecast to complete a set of user stories or other work items during a fixed time duration, known as a sprint. Generally speaking, sprints are one, two, or four weeks long. It's up to the team to determine the length of a sprint. Once a sprint cadence is determined, the team perpetually operates on that cadence. Fixed length sprints reinforce estimation skills and predict the future velocity for the team as they work through the backlog

Hold the Sprint Planning Meeting

At the beginning of a sprint, you should hold the sprint planning meeting with your team. The sprint planning meeting is a ceremony that sets up the entire team for success throughout the sprint. In this meeting, the entire team discusses the sprint goal and the stories in the prioritized product backlog. The development team creates detailed tasks and estimates for the high-priority stories. The development team then commits to completing a certain number of stories in the sprint. These stories and the plan for completing them become what is known as the sprint backlog

Start the Sprint in JIRA

Name the sprint. Some teams name the sprint based on their sprint goal. If there is a commonality between the issues in the sprint, name the sprint around that theme. Add a duration of the sprint and start and end dates. The start and end dates should align with your team's schedule Following are the steps to be followed after starting a newsprint

Hold the daily standup meetings
View the Burndown Chart
View the sprint report
Hold the sprint review meeting
Hold the sprint retrospective meeting
Complete the spring it JIRA

If the sprint has incomplete issues, you can move the issue/issues to the backlog, move the issue/issues to a future sprint, or move the issue/issues to newsprint, which Jira will create for you

What are the Best Features of Using JIRA to Drive the Agile Transformation?

Agile Project Management

The platform primarily focuses on agile project management, offering the Scrum approach. It also has the capability to capture regulatory evidence at different stages of the development process. Moreover, Jira Software supports all sorts of estimation techniques, be it by hours, story points, or more. This way, you can make sure that you are working with accurate data at all times

Customizable Workflows

With Jira, you can even create custom workflows and issue schemes in more specific cases. This will take much of your developers’ burden off their shoulders, and empower your project management units to maximize the potential of their idea. If you’re using Jira’s cloud-based solution, the configuration will take even less time And custom dashboards are a one-stop-shop for all of the information you need to organize projects, and achievements in a single view

Product Roadmaps

It is a plan of action for how a product or solution will evolve over time. When used in agile development, a roadmap provides crucial context for the team's everyday work and should be responsive to shifts in the competitive landscape. To build a roadmap, product owners take into account market trajectories, value propositions, and engineering constraints. Once these factors are reasonably well-understood, they are expressed in a roadmap as initiatives and timelines. Once a roadmap is built, it needs to be shared with the entire product team so everyone understands the vision and direction

Bugs and Defect Management

JIRA helps you to quickly capture, assign and prioritize bugs and track all aspects of the software development cycle. JIRA's powerful workflow engine provides a clear view of a bug's status, and automation keeps you in the know with notifications as issues transition from backlog to done. JIRA gives you full visibility and control of your products' end-to-end development Once you have identified a bug, create an issue and add all relevant details, including descriptions, severity level, screenshots, version, and more. Issues can represent anything from a software bug, a project task to a leave request form, and each unique issue type can have its own custom workflow

Powerful Search and Filtering

JIRA Software comes with advanced search capabilities powered by Jira Query Language(JQL) that offers teams detailed views into their work. Query results can be saved and used as filters and views across Jira (including boards). The three flavors of search in Jira - Quick, Basic, and Advanced - can help you find important information about your projects

Advanced Reporting

JIRA offers reporting in a number of different formats. Project reports that are available from the home screen of the selected project, Gadgets that can be added and arranged in Dashboards and for each filter, the issue navigator offers various output formats that can be used in third-party reporting software

How To Build An E-Commerce for wholesale dealers

Introduction

Electronic commerce is buying and selling of products through online services. In E-commerce for wholesale the products are sold in bulk from the e-commerce site instead of selling individually to each person. Wholesale reduces the cost of doing business and is intermediate between manufacturer and retailer. Since items are sold in bulk there might be larger orders. So the products can be sold quickly without much need for marketing. Ecommerce for wholesale is completely new but it is growing fast these days. There is a trigger in growth because of the increase in internet connection and smartphone use

Overview of market share

The global ecommerce market size was valued at USD 6.64 trillion in 2020 and is expected to grow by a compound annual growth rate (CAGR) of 18.7% from the period 2021 to 2028. The COVID-19 pandemic brought about a shift in wholesale dealer's preference for online shopping, creating avenues for growth. The factors that affected ecommerce business outlook are the changes in consumer behaviour, increase in order quantity, physical stores closure and disruption in supply chain While retail sales dipped in 2020, e-commerce sales witnessed a surge. Several businesses are now focused on moving their customer online Established organizations and large enterprises are moving towards online business due to lesser expenditure in communication and infrastructure. E-commerce offers the organization an easier reach for the dealers/customers, and hence necessary exposure to business is also achieved. Nowadays, the marketing options are in abundance due to the popularity of social media applications, which helps in driving the market for e-commerce towards a growth path

How e-commerce for wholesale dealers Works

In wholesale e-commerce, the products are sold in bulk and the wholesaler is the middle man in the supply chain which starts from Producers. The wholesale dealers buy the product in bulk from a manufacturer or dealer through their online site. Here the dealer places his order for products on the website. The concerned organization will process the order and supply the goods to the wholesale dealer. It is then sold to another wholesale dealer or directly to the consumers

What are the best features to have in e-commerce for wholesale

Some of the best to have features of wholesale eCommerce are

Payment Flexibility

The payment gateway and the payment options offered will all make a difference in the success of a business. Users of e-commerce websites should have payment flexibility. They should be able to pay in any way that will work for them. A payment gateway with advanced functionalities should be integrated to support the business and its growth

Easy to Use checkout feature

Adding items to the cart and then checking them out to proceed with payment must be an easy process. In case the checkout feature is too complicated the buyer may feel irritated and abort the process of buying products. So this should be easy to use a feature

Ease of Navigation

The key to the success of any e-commerce website is east to Navigation. The navigation should be easy, clear, and user-friendly. Extreme care should be taken while designing and developing the User Interface (UI). Clear navigation will improve the User Experience (UX) which will attract more users

User Reviews

Most people who shop on the website read the reviews before purchasing the product. People think that negative reviews will diminish sales. But it is actually not true. It is often positive to have negative reviews. When there are only positive reviews people think that they are fake. When there are true reviews, it will attract more people to the website

Security

The e-commerce platform should be secure for the users. Using features like an SSL certificate for a secure connection between user and e-commerce site, firewall to provide a gateway between networks and allow only authorized traffic, two-factor authentication for a user to log in would be ideal for any e-commerce site

Tech Stack

Front end for E-commerce

The front end for an e-commerce website can be developed using JavaScript libraries like Angular or React, CSS, HTML

Back end for E-commerce

The programming languages used for server-side coding are C#, PHP, and Python. Depending on the requirement of the project and the goals of the business-appropriate language is selected

Third-party Services

The e-commerce website needs to be integrated with third-party services like payment gateways, shipping modules, CRM, and analytics tools for the effective functioning of the e-commerce site

Introduction

Video on Demand platform delivers direct fast and high-quality transactional video to its customers to watch on TV or PC. It helps users to access online content from video libraries. Users can watch the videos according to their own convenience from any device. VOD is a dynamic feature and is offered by Internet Protocol. It is transmitted through Real-Time Streaming Protocol. It is the future of online content delivery

Overview of market share

The global video-on-demand market size is projected to reach 159.62 billion USD by the end of 2027. The worth of the VOD market was USD 53.96 billion in 2019 and will exhibit a CAGR of 14.8% during the forecast period, 2020-2027. This information was published by Fortune Business Insights. Smartphone penetration is increasing across the world which will create several opportunities for market growth. The availability of low-cost cloud platforms will also be a favor for market growth. VOD is gaining popularity over the last few years

How VOD Works

In VOD the video content is stored on a server in digital form. When a User makes a demand request, it is compressed and transmitted through the internet. Then at the user’s end, the video is again decompressed, decoded, and stored on a video server in the user’s device. Here, the user has full control of the video. Video can be watched instantly, fast-forwarded, rewinded, or paused. These capabilities are available only in VOD and not in other traditional methods. These videos can also be downloaded and watched later A library contains all videos in uncompressed format. Transcoders are used to compress videos before transmitting them through the internet

What are the best features to have in VOD

Access for Multiple Users

Multiple users should be granted access to view the video contents. Enough security measures need to be handled to make sure that the video content is available only to the intended Audience and not to external people

Multiple viewing options

Users should have multiple viewing options to view them on a wide range of devices. When users have many options they will show more interest in viewing the videos

Recording Live Events

The Live events can be captured, edited, and recorded. This can be stored in the video content library for the ease of access to the User

Video Analytics

This will help to analyze which videos are most watched, which videos are popular, and what type of devices are used for watching. This will help to make business decisions

User interactive

The videos should be made user-interactive. For example, for education-related videos quizzes can be inserted. Surveys can be included to get feedback about a product from users

What are the Benefits of VOD

There are multiple benefits of VOD. Few of them are listed here

The videos will be available in the library for a long period of time. Users can access the video at any time even after years. The content can thus reach a large audience
The user has the option to preview, edit, add or remove the content in the video. Even effects or animation can be added to the video
These videos can also be viewed offline. This will help people to watch it at their own convenient time.
Cost-wise VOD will be cheaper compared to other traditional ones. In the case of VOD, there might be offer packages or discounts which will attract more users
Also, VOD gives us total control of our content. The user has the flexibility to create his own content without compromising his creativity

Cloud Migration : Lift & Shift Strategy

Lift-and-shift is the process of migrating a workload from on premise to Cloud with little or no modification

Introduction

It allows your business to modernize its IT infrastructure for improved performance and resiliency at a fraction of the cost of other methods

Overview of Market Share

What are the best features to have?

Workloads that demand specialized hardware, say, for example, graphical cards or HPC, can be directly moved to specialized VMs in the cloud, which will provide similar capabilities
A lift and shift allows you to migrate your on-premises identity services components such as Active Directory to the cloud along with the application
Security and compliance management in a lift and shift cloud migration is relatively simple as you can translate the requirements to controls that should be implemented against compute, storage, and network resources
The lift and shift approach uses the same architecture constructs even after the migration to the cloud takes place. That means there are no significant changes required in terms of the business processes associated with the application as well as monitoring and management interfaces
It is the fastest way to shift work systems and applications on the public cloud because there isn’t a need for code tweaks or optimization right away
Considered the most cost-effective model, the lift and shift help save migration costs as there isn’t any need for configuration or code tweaks. In the long run, these savings could give way to extra spending if workload costs are not optimized
With minimal planning required, the lift and shift model needs the least amount of resources and strategy
Posing the least risk, the lift and shift model is a safe option as compared to refactoring applications especially in the scenario where you don’t have code updating resources

Cloud Migration Steps: Ensuring a Smooth Transition

First, choose which platform that you wish to migrate to
Examine all the connections in and out of the application and its data
If you are lifting and shifting more than one application, then you may need to consider automating multiple migrations
You should consider containerization to replicate the existing software configurations. This will also allow you to test configurations in the cloud before moving to production
Back up the databases from the existing system as well as supporting files. When the new database is ready, restore the backups
Once migrated, test the application
Check that all the current data compliance and regulatory requirements are running in the new cloud deployment. Run your normal validation tests against the newly migrated application
Don’t be tempted to introduce new features during the migration. This can lead to many hours of additional testing to make sure you have not created new bugs
Retire your old systems once testing is complete

Why do we use Jira ?

What is Pytest ?

Pytest is an automation testing framework in python which is used for testing software applications.

Why do we use Pytest ?

What is Rest API ?

EXECUTION FLOW OF GITHUB FOR JIRA THROUGH PYTEST

To update the jira tickets through pytest, we need to know about the Github workflow execution, Jira Rest API endpoints, pytest configurations

Things we need to know for execution:

To create a github workflow file to execute pytest test cases when a PR is merged
To configure pytest test cases with jira API endpoints to send the workflow results

JIRA REST API ENDPOINTS

Prerequisites for Jira API Integration:

Steps to create API Token:

STEP 1: Login to Jira with the registered Email ID Use this link https://id.atlassian.com/login to login into the jira

CONFIGURING GITHUB WITH JIRA:

There are two ways in configuring github with jira, one is by providing the PR link in a separate field of jira ticket and the other way is by configuring github app in jira

1. Configuring jira with PR link:

We can able to identify the ticket information by providing the PR link in a Jira ticket
PR Link should be provided in the custom field of Jira ticket
After placing the PR link in custom field, we need to use the Jira Search API endpoint through Jira Query Language(JQL) syntax

2. Steps to configure PR link in Jira Ticket on custom field:

Go to Project Board > Project settings > Issue types
Select the Paragraph field type > Enter the field name and description
Click Save changes

3. Configure github app with jira:

Build APIs in Python Using FastAPI Framework

FastAPI could be a modern, high-performance, web framework for building APIs with Python language. Good artificial language frameworks make it easy to provide quality products faster.

ASGI:

Does FastAPI need Uvicorn?

The main thing needed to run a FastAPI application in an exceedingly remote server machine is an ASGI server program like Uvicorn.

Using WSGIMiddleware:

Need to import WSGIMiddleware.Then wrap the WSGI (e.g. Flask) app with the middleware. Then mount that beneath a path.

FastAPI Different from other Frameworks:

Let us walk through a journey of building a CRUD application with FAST API and understand how transactions, persistence/database layer, exception handling, and request/response mapping are done.

Building a CRUD Application with FastAPI

Setup:

Start by creating a brand new folder to carry your project called "sql_app".

Create and activate a new virtual environment:

Next, create the following files and folders for fastapi:

Install the following dependencies:

In the sql_app/main.py ,and define an entry point for running the fastapi application:

In this case, we stated the file to run a Uvicorn server. Before starting the server via the entry point file, create a base route in api.py:

Difference between Database Models & Pydantic Models:

Models.py:

database.py:

schema.py:

FastAPI interactive documentation

Structuring of FastAPI:

By using __init__ everywhere, we are able to access the variables from everywhere in the app, similar to Django.

Models:

It is for your database models, by doing this you'll import the identical database session or object from v1 and v2.

Schemas:

Settings.py:

Views:

This is optional if you're visiting render your frontend with Jinja, you'll have something near MVC pattern.

Core views

v1_views.py
v2_views.py

It would look something like this if you wish to feature views.

Tests:

It is good to own your tests inside your backend folder.

APIs:

Create them independently by APIRouter, rather than gathering all of your APIs inside one file.

How to use Apache spark with Python?

Apache Spark is based on the Scala programming language. The Apache Spark community created PySpark to help Python work with Spark.

Apache spark:

Spark Python:

PySpark :

PySpark features:

- Spark SQL brings native SQL support to Spark and simplifies the process of querying data stored in RDDs (Spark's distributed datasets) as well as external sources. Spark SQL makes it easy to blend RDDs and relational tables. By combining these powerful abstractions, developers can easily mix SQL commands querying external data with complex analytics, all within a single application.

- DataFrame A DataFrame is a distributed data collection organized into named columns. It is conceptually equivalent to relational tables with advanced optimization techniques. DataFrame can be built from a variety of sources, including Hive tables, Structured Data files, external databases, and existing RDDs. This API was created with inspiration from DataFrame in R Programming and Pandas in Python for modern Big Data and data science applications.

- Streaming is a Spark API extension that allows data engineers and data scientists to process real-time data from a variety of sources like Kafka and Amazon Kinesis. This processed data can then be distributed to file systems, databases, and live dashboards. Streaming is a fault-tolerant, scalable streaming processing system. It supports both batch and streaming workloads natively.

- Machine Learning Library (MLlib) is a scalable machine learning library made up of widely used learning tools and algorithms, such as dimensionality reduction, collaborative filtering, classification, regression, and clustering. With other Spark components like Spark SQL, Spark streaming, and DataFrames, Spark MLLib works without any issues.

- Spark Core is a general execution engine of Spark and is the foundation upon which all other functionality is built. It offers an RDD (Resilient Distributed Dataset) and supports in-memory computing.

Setting up PySpark on Linux(Ubuntu)

Follow the steps below to setup and try pyspark: Please note that python version 3.7 or above is required. Create a new directory. Navigate to the directory.

Resemblance and Explanation of Golang vs Python

Everyone has been looking for the best programming language to use when creating software and also there has recently been a battle between Golang and Python.

Golang

Features of Golang

Simplicity

Robust standard Library

It has a strong set of library packages, making it simple to compose our code.

Web application building

This language has garnered as a web application building language owing to its easy constructs and more agile execution speed.

Concurrency

Go deals with Goroutines and channels.
Concurrency effectively makes use of the multiprocessor architecture.
Concurrency also helps huge programs scale more consistently.
Some notable examples of projects written in Go are Docker, Hugo, Kubernetes, and Dropbox.

Speed of Compilation

Go offers a much more powerful speed of completion and compilation than several other popular programming languages.
Go is readily parsable without a symbol table.

Testing support

The "go test" command in Go allows users to test their code written in '*_test.go' files.

Pros:

Ease to use - Go’s core resembles C/C++, so experienced programmers can pick up the basics fast, and Simple syntax is easy to understand and learn
Cross-platform development opportunities - Go can be used with various platforms like UNIX, Linux, Windows, and Other Operating systems, and Mobile devices also.
Faster compilation and execution - Go is a compiler-based language so it completely reads the code and executes due to this it executes faster than c,c++, and java.
Concurrent - Run various processes together and effectively

Cons:

Still developing - Still in development
Absence of GUI Library - There is no native support
Poor Error handling - The built-in errors in Go don't have stack traces and don't support the usual try/catch handling techniques.
Lack of frameworks - Minimal amount of frameworks
No OOPS Support

Here is the simple "Hello World" programme in the Go language.

Output:

Let's discuss the above program,

package main - Every Go program begins with code inside the package main
Import “fmt” - its an I/O function.
func main - This function always needs to be placed in the main package.{} Here we can write our code/logic.
fmt.Println - Print function, print the text on the screen.

Why Go?

It's a statically strongly typed programming language with a great way to handle errors.
It allows using static linking to combine all dependency libraries and modules into one single binary file based on the type of the OS and architecture.
This language performs more efficiently because of its CPU scalability and concurrency model.
This language offers support for multiple libraries and tools, so it does not require any 3rd party libraries.

Frameworks for Web Development: Gin, Beego, Iris, Echo, and Fiber

Python

Features of Python

Free and open source

It's free and open source, which means the source code is available to the public. So we easily download and use it

Easy to code

Object-oriented programming

OOPS is one of the essential features of Python. Python supports the concepts of classes, objects, encapsulation, and object-oriented language.

GUI Programming support

A graphical user interface can be developed by using modules such as PyQt5, PyQt4,wxPython, or Tk in python.

Extensible and portable

- - Python is an extensible language.
  - We can formulate some Python code into the C or C++ language.
  - Furthermore, we can compile that code in the C or C++ language.
  - Python is also a very portable language.
  - If we have Python code for Windows and want to run it on platforms such as Unix, Linux, and Mac, we do not need to change it. This code is platform-independent.

Interpreted and High-level language

- - Python is a high-end language.
  - When we formulate programs in Python, there is no need to remember the system architecture, nor do we need to manage the memory.
  - Like in other programming languages, there is no requirement to compile Python code, making it easy to debug our code.
  - Python's source code is converted to an instantaneous form known as bytecode. Python is classified as an interpreted language because Python code is executed line by line.

Pros:

Simple syntax: Easy to read and understand

Larger Community support: Python community is vast

Dynamically typed: The variable type is not required to be declared.

Auto memory management: Memory allocation and deallocation methods in Python are automatic because the Python developers created a garbage collector for Python so that the user does not have to manually collect garbage.

Embeddable: Python can be used in embedded systems

Vast library support: Lots of Libraries are available. For Example, TensorFlow, Opencv, Apache spark, Requests and Pytorch etc.,

Cons:

Slow speed

Python is an interpreted language, so the code will be executed line by line, which often results in slow execution.

Not Memory Efficient

Python's auto-memory management makes it unsuitable for memory-intensive tasks. Because of the flexibility of the data types, memory consumption is high.

Weak in mobile computing

Python is typically used for server-side programming. It is not used in the development of client-side or mobile applications. because it is inefficient in terms of memory and processing speed.

Runtime errors

Because Python uses dynamic typing, the data type of a variable can change at any time. In the future, a string could be stored in an integer number variable, causing runtime issues.

Poor database access

Why Python?

Comparison of Go vs Python:

Case studies:

Concurrency:

Output:

Exception Handling :

Output :

Python supports exception handling, but Go doesn't.

Go vs Python: Which is Better?

Conclusion

Python and Golang are winners in their respective areas depending on the specific capabilities and underlying design principles of the language

1.Maturity

It's difficult to make conclusions about Go vs Python because comparing a mature language to a young one doesn't seem fair. Python may be the winner here

2.In ML and Data science Usage

3.Performance

The main advantage of Go is speed. However, Python is slow when it comes to code execution.

4.Microservices and Future Readiness

Fast API is based on standards such as JSON Schema (a tool for validating the structure of JSON data), OAuth 2.0 (an industry standard protocol for authorization), and OpenAPI (an open application programming interface).

Cons

In FastAPI there is insufficient Security and also it will support OAuth.
Because FastAPI is relatively new, the community is small compared to other frameworks, and regardless of its detailed documentation, there are very few external educational materials.

Difference between Flask and FastAPI:

Performance:

Data Validation:

Documentation:

HTTP METHODS:

Flask	FastAPI
@app.route("/get", methods= ['GET'])	@app.get('/get', tags=['sample'])

Production Server

At some point, you’ll want to deploy your application and show it to the world.

Flask

FastAPI

Asynchronous Tasks

Flask

In Flask Async can be performed by thread or multiprocessing or use some tools like celery, Create await/async for handling routes

Installations

Example:

FastAPI:

In FastAPI there is a default AsyncIO. So we can simply add the async keyword before the function.

FastAPI was Built with Primary concerns

Speed and Developer Experience
Open Standards.

FastAPI can connect Starlette, Pydantic, OpenAPI, and JSON Schema.
FastAPI uses Pydantic for data validation and Starlette for tooling making it twice as fast as Flask and equivalent to high-speed web APIs written in Node or Go.
Starlette + Uvicorn supports async requests, while Flask does not.
Data validation, serialization and deserialization (for API development), and automatic documentation are all included (via JSON Schema and OpenAPI).

Which Framework is Best for AI/ML

Migrating Flask TO FastAPI :

The Application object in Flask and FastAPI is

Simple Example for Migrate Flask to FastAPI:

Flask Application

1.To Migrate the Flask to FastAPI we need to install and import libraries.

2. URL Parameters (/basic_api/employees/)

In FastAPI the request methods are defined in the methods FastAPI objects. For Example @app.get, @app.post, @app.put.

The Request Methods in Flask and FastAPI is

Query Parameters:

Like URL Parameters, Query parameters are also used for managing the state(For sorting or Filtering).

Flask

FastAPI

Run the server in Flask And FastAPI

Main (Flask)

Main (FastAPI)

And Finally the FastAPI Application looks like :

FastAPI Application

Use ASGI Application web server Uvicorn to run the FastAPI application (uvicorn.run(app)).

When Should you choose FastAPI instead of Flask and Django?

Native Async Support:The FastAPI web framework was created using the ASGI web server. Native asynchronous support eliminates inference latency.
Improved latency: As a high-performance framework, the framework's total latency is lower when compared to Flask and Django.
Production-ready:With the FastAPI web framework's auto validation and short defaults, developers may easily design web apps without rewriting the code.
High Performance: Developers have access to the key functionalities of Starlette and Pydantic because they are compatible. Needless to say, Pydantic is one of the quickest libraries, and as a result, overall speed improves, making FastAPI the preferred library for web development.
Learn Simple:This is a minimalist framework so it is easy to understand and learn.

Flask Or FastAPI: Which is better

S.No	Flask	FastAPI
1.	Flask is a micro web framework to develop small-scale web applications and Rest API. Flask is depends on WSGI toolkit (werkzeug, Jinja2)	FastAPI is considered one of the Fastest frameworks compared to the flask. FastAPI is built in Pydantic and starlette.
2.	Flask is built in Web Server Gateway Interface(WSGI)	FastAPI is built in Asynchronous Server Gateway Interface(ASGI)
3.	It does not have any inbuilt documentation such as swagger UI and needs to add some extensions like Flasgger or Flask RESTX.	In FastAPI it has inbuilt documentation like (docs and redocs).
4.	There is no Inbuilt data validation in Flask, we need to define the data type in requests.	In FastApI there is an Inbuilt data validation that will raise the error if the user provides an invalid data type.
5.	Flask is more flexible than Other frameworks.	FastAPI is flexible in code standards and it does not restrict the code layouts.

Why and when choose custom Software development?

Custom software development is the process of designing, developing, deploying and maintaining software for a certain set of Users or a specific Organization. Any software will meet the generalized need of the end-users

Introduction

Custom software development is the process of designing, developing, deploying, and maintaining software for a certain set of Users or a specific Organization. Any software will meet the generalized need of the end-users. The existing software may not address all the needs of the Organization. In such a case they move in for customization of the existing software. Customized solutions are developed to meet the needs of the User

Overview of market share

Custom Software Development Services Market is huge and is growing at a moderate speed with substantial growth rates over the last few years and is estimated that the market will grow significantly in the next few years. The Custom Software Development Services Market is driven by the growing requirements for customized software among Organizations. Moreover, organizations are always looking for reducing long-term costs. Custom software development is becoming popular among organizations that are largely looking for scaling up of their business operations. A holistic evaluation report of the market is provided by the Global custom software development services market. The report offers a comprehensive analysis of key segments, trends, drivers, restraints, competitive landscape, and factors that are playing a substantial role in the market.

How custom software development process Works

The process followed in custom software development is same as SDLC. It starts with Planning and Analysis followed by Design, Development, Testing, and finally maintenance of the completed product. The main goal of planning and analysis is to collect as much data as possible. The design transforms the requirements into a detailed system design requirements document. It is like a blueprint for the solution which is used for developing the code. Developing code is the actual implementation phase, which is followed by rigorous testing. Testing is done until all issues are identified and resolved. Finally, the product is deployed into the live environment. And the product gets into the maintenance phase.

Reason to choose custom software development

Generally, developing an application from scratch is a complex and time-consuming process. If there is not much time and a solution needs to be implemented as quickly as possible, then custom software development would be a better choice. The next factor to be considered is software development cost. Ready-to-use applications can save the budget if they provide the desired functions and match the standard requirements and do not need any customization. In case the ready-to-use application can’t meet the demands of all kinds and the development team needs to handle complex processes and comply with high security and industry regulations then a custom software development process would be the best option.

What are the Benefits of the Custom Software development process

Some of the benefits of the custom software development process

Uniqueness

One of the important benefits of custom applications is uniqueness. Tailored solutions are built to fit the user’s specifications. A development team experienced in custom software development help to deliver a solution that will include the features requested.

Flexibility & Scalability

Regular software cannot be manipulated and it will remain constant. It will become unsuitable to keep using it. But custom software can be scaled according to the needs of the company and easily integrated with business. So the user need not change according to the application but the application can be changed according to the user.

Cost effectiveness

Readily available software might be less expensive but it might have some recurring costs which will make it less beneficial. They might also lack some critical functionality. In such cases developing a product from scratch might cost more. When existing software is customized, a huge sum of money need not be invested.

Security

While customizing or developing software, the important feature that needs to be handled is security When an organization needs to support expensive security protocols, it might be an add-on cost to them. But with customized software, they can decide about the security technology to be used and choose one which is ideal for their business.

Team Capabilities

Team experience and technical skills A software team with strong technical skills, in-depth knowledge of the latest technologies, and experience with multiple companies need to be considered for customizing software.

Cost Structure

When a third party is hired for customizing software, it should be ensured that they give a clear picture of all the costs involved and do not keep the costs hidden.

Communication Skills

The custom software development team should be strong in communication skills. Their strong communication skills will help them to understand the details of the unique requirements needed by the client. When they have a clear understanding, they can carefully design and develop software with accuracy.

Regular customer interactions can be automated partially or fully using a banking chatbot which is available 24/7. A voice enabled

What is Chatbot?

chatbot is a variation of a conversational AI solution. It leverages NLP combined with speech-to-text(self-developed or already existing platforms) and automates speech recognition to deliver resolution immediately. Voice Assistants can either be a complete voice-based model or as a multimodal chatbot supporting both text and voice

What is Dialogflow?

Dialogflow is a natural language understanding platform used to design and integrate a conversational user interface into mobile apps, web applications, devices, bots, interactive voice response systems, and related uses

Overview of Market Share

The global chatbot market size was estimated at USD 430.9 million in 2020. The growth is expected to be driven by the increasing adoption of customer service activities among enterprises to reduce operating costs. A chatbot is an interactive application developed using either a set of rules or artificial intelligence technology. A chatbot is basically developed using AI technology or a set of rules. It is designed in such a way that it can interact with humans through text. To assists users in various sectors, it is integrated with other messaging services. Various innovative ideas are implemented in Machine Learning (ML) and Artificial Intelligence (AI) technologies which will enhance the features of chatbots, which, in turn, will create greater demand for chatbots. Since businesses are looking for ways to automate their sales and other services Chatbots are becoming popular. This helps the organizations to stick to the schedule at reduced cost.

How do Chatbots work?

1A user sends a text/voice message to a device or an App
The App/Device transfers the message to Dialogflow( via detecting API )
The message is categorized and matched to a corresponding intent (Intents are defined manually by developers in Dialogflow)
We define the following actions for each intent in the fulfillment (Webhook)
When a certain intent is found by Dialogflow, the webhook will use external APIs to find a response in external databases
The external databases send back the required information to the webhook
Webhook sends a formatted response to the intent
Intent generates actionable data according to different channels
The actionable data go to output Apps/Devices
The user gets a text/image/voice response

How to build your first Chatbots?

Agent: An agent is merely another term used to refer to the chatbot. While using Dialogflow, you will find that many people start off by asking you to ‘name the agent.’ This just means giving your chatbot a name, so even in this context, it's one and the same Intent – ‘Intents’ are how a chatbot understands Expressions Responses: This is the chatbot’s output that is aimed at satisfying the user’s intent Entities: ‘Entities’ are Dialogflow’s mechanism. It helps to identify and extract useful data from the natural language inputs given by user. Actions & Parameters are also Dialogflow mechanisms Actions & Parameters These too, are Dialogflow mechanisms. They serve as a method to identify/annotate the keywords/values in the training phrases by connecting them with Entities We will see how to create a chatbot in Dialogflow using the following

Step1: Login with DialogFlow Account

Go to https://dialogflow.cloud.google.com
Click ‘Go to console’ in the top right corner
Login with a Gmail account

Step2: Create a new Agent

Start off by clicking ‘Create Agent’ in the column menu to your left
Give your Bot a name! We’re going to call ours a ‘Testing’
Be sure to select your time zone and language as required
Click ‘Create’

Step3: Create a new Intent

Click “Intent” on the left side
Add the Intent Name and Training Phrases
If you have already created Entity, Please mark the entity for the corresponding questions. Here I have created one entity as “Cheque” and marked that keyword to that training phrase
After that, we need to add the response in the Intent
Click “Save” in Intent

Step4: Check Question

We are able to check the questions on the right side of the top corner and it will give the intent name, Entity name and answer also

Best features

Some best features are given below

Self Service Customer Support Self Service via a voice bot is more scalable and customer-centric. Giving your customers a voice bot as the first mode of communication can help them resolve their queries faster and for major queries, the AI-enabled voice bot can transfer the call or the message to the right agent
Zero Wait Time Calling any customer support center can be a nightmare for most people, basically, because of the wait time and redirections. Enabling FAQs on automating general queries on IVR, Alexa or Google Assistant can save a lot of time and the agent can take over or the call can be transferred to the agent only for critical issues
24/7 Availability Humans require rest, but machines do not. Even if your agent is not available, the voice bots can resolve the queries for your customers and take their details in case of urgent queries. And your agent can contact them at their earliest convenience
Break from Monotonous Texts Provide a multimodal Intelligent Virtual assistant supporting both chat and voice, rather than just a text-based chatbot. Just a text-based chatbot requires a lot of patience, and time from the user’s end. And also sometimes it becomes difficult to understand voiceless messages as it lacks sentiments. AI-enabled voice bot is highly automated, intelligent, and customer-friendly; making it a need of the hour for brand-customer engagement platforms
No human contact Pandemic made it really clear the need for an automated customer support system, as most customer support offices were closed down. Many businesses and banking institutions were seen adopting IVR support for resolving customer queries like Kotak, ICICI, etc
Save Cost An automated AI-enabled voice bot increases your team’s productivity, by taking care of all repetitive queries. Your team can just focus on critical queries, thus saving a lot of time and money for your business
Increased Productivity Using voice bots, your customers can handle multiple tasks simultaneously, and in one call. Customers can schedule appointments, organize and modify meetings, check balance, do transactions, get account details, set reminders, etc

How To Build An Asthma Medication And Control app

Asthma Control App, the best medication reminder app, ensures you can take the stress out of medication schedules. A secure, data-driven service supports effective health management for you and those you care for

Introduction

Asthma Control App, the best medication reminder app, ensures you can take the stress out of medication schedules. For supporting effective health management, a data driven and secure service is required. Getting digital reminders and missed dose notification is a simpler and smarter way to manage your medication.

Overview of Market share

Today around 300 million people are suffering from asthma. In a period of 8 years it may rise to 400450 million, which is an increase by about 50%. The asthma apps are currently used by less than 1% of the target group. Analysis is being done to know the reason for this low user adoption rate. What are the reasons behind this low user adoption rate and why with the current asthma app solutions, mHealth publishers have managed to just barely scratch the surface on this market? To answer these questions, let’s look at the Top 10 asthma apps in 2017. The list is exclusive to asthma mobile apps with a core business to serve and empower asthma sufferers. The asthma apps are mainly to help and serve the people suffering from asthma. There are nearly 1,500 mobile apps for asthma patients in Google play store and Apple app store. The preferred mobile platform is iOS accounting for 100% of all top 10 core asthma apps releases from mHealth publishers. 50% of these apps are also published on Android

How does the Asthma control app works?

For many, the concept of an Asthma control app supports you to feel confident with appropriate handling and administering of medication. The asthma control app does this by utilizing digital reminders to notify you when you need to take your medication And it's not only about providing reminders, but also keeping those in your network updated. Missed medication alerts can inform family, carers, and doctors when a dosage has been forgotten to ensure the patient isn't at risk of complications related to mismanaged medication delivery. The Asthma control app, helps to take the right dosage at right time and thereby it helps to have a control over their medication schedule. Something most of us would appreciate with so many other things to remember The app isn't just useful for patients, but carers too. It is very essential to make sure that our family member or friend takes their medication at correct schedule. Everyone's medication requirements differ, which can be tricky to manage, especially if you're assisting with distributing the medication to multiple family members, perhaps elderly parents or children with health conditions. In such cases the flexibility to create customized reminders for your medication schedule helps and makes life easy. Many of us may take common medications which are taken at the same time daily such as contraceptive pills, other medicines may have complicated schedules with several medicines needing Some of us may only be taking common medications that must be taken at the same time each day such as contraception, others may be operating to more complicated schedules with various medicines needing to be taken at regular intervals throughout the day, that's where a medication reminder app can support you

What are the best features to have

Take full control of your asthma with Asthma Control App

A visual dashboard presents your patient's key results. We can get a glimpse of the patient’s actual condition at any time by seeing the progress and trends for various factors like lung tests or inhaler technique rating, in real time. And because the Asthma Control app connects your Inhalers & lung monitors with your smartphone seamlessly, you know you're getting not only medical-grade results but peace of mind. Isn't that all the smarter?

Never miss a dose

Schedule medicine intake on the app and get reminded every single time

The one time you want to keep your family connected

Asthma control app will help you to your family connected with you

Friends connect

By connecting with your friends they will also get notified of the medication you have taken or missed or skipped by receiving a push notification

Notifications and Reminders

It is important for patients to have certain reminders and notifications to get their medication on time. However, the time and frequency of notifications should be adjustable

Inhaler technique

The asthma control app is designed to reach inside your lungs and if your medication is actually only hitting the back of your throat or, worse still, staying on your tongue, you're not giving it enough of a chance of doing its thing

Peak flow meters and spirometers support

By enabling Bluetooth, patients can record and share their health data measurements at anytime and anywhere. This will help the patients to regularly record Facilitating the ability for patients to regularly record and upload data sets about their lung function can keep doctors more informed about a patient's condition than periodical in-person assessments With the portability of the Asthma control app, peak flow meters, and spirometers, patients can share key lung function data with their doctors from anywhere

How To Enable Green Field Systems on Azure

A MAJOR ENERGY player, multinational integrated oil and gas company, is one of the seven big oil companies in the world

A MAJOR ENERGY player, multinational integrated oil and gas company, is one of the seven big oil companies in the world, needed some governance and framework around provisioning of azure resources. The main objective of client was to come up with an integrated solution for Azure Service Orchestration for various mobile, web, analytics and machine learning projects

Current Challenges

The client has an existing architecture and system setup to support specific topology of applications in pre-production. The cost involved in building the infrastructure and the technical dependencies to maintain and enhance is too high
Industry-standard well-architected framework principles were not followed. The client is stuck with a solution that is not scalable. Ex: takes weeks to add support for a different topology of apps
Time taken to set up and tear down infrastructures is causing a huge delay in business deliveries and directly impacting the business deliveries and operational cost
Testing the service configuration and having a first-time-right infrastructure for each system type is a major challenge in any cloud provider

Present System

In the existing system, the Engineer has to know about azure resources and every service to provide the resources through the Azure portal. Creating or updating the resource with right configuration is a time consuming process. Also, there is a huge chance for human error in configuring any specific environment for a specific project The issues faced in the current system are

80% Probability of Human errors
Lack of Control in Cast and Usage
Infrastructure Topology - Not Scalable
Delay in provision of resources

Proposed system - Architecture & Benefits

A simple Do-It-Yourself UI has been delivered to all the engineers. The engineers can just click on the UI and decide what type of system they want to build and drag and drop components
A role-based system is set up behind the screens to control the generation of infrastructure as per the definition in AD(Active Directory) or any other provider
The opportunity was also utilized to identify resources in Azure that were causing a lot of overhead costs and maintenance costs. These were replaced with free open-source alternatives with recommended architecture standards
Applications / Systems built are 100% configurable with adoption to best practices from industry standards including usage of vaults / KMS for secrets

Automated Infrastructure Generation

Dependency on experienced and mature engineers to be always around to build systems is impossible and costly. We eliminated this need by 100%. Anyone without prior experience can now request/generate and manage infrastructure
Cloud agnostic approach of engaging terraform ensured 100% portability for the client to repeat the same across other cloud providers like AWS
Tested code for infrastructure ensures that the developers or DevOps engineers do not end up debugging the same issues. Over a period of 3 months, the reliability of systems improved by 60% and will continue to grow
Modernization of existing systems as part of this opportunity also reduced unwanted licensing costs
Time to market for the infrastructure was reduced from 3 weeks to 1 day. This is a major win for the client to onboard new customers and delivered direct business results
Time taken for Change management and propagation of infrastructure changes has significantly reduced from a couple of hours to a couple of mins due to automation in place
