Introduction

Container bundles up the OS and microservice runtime environment such as source code, dependencies, system libraries, etc. There are many tools available in the market for configuring the containers. Some of them are Kubernetes (including AKS, EKS and GKE) and ECS. Multicluster management is for managing many k8s clusters in an environment. For this, we have tools like rancher and kubesphere. In this article, Kubernetes deployment through Istio and Rancher multicluster management is covered.

Istio is a service mesh which provides a language independent and transparent way for easy automation of application network functions. Istio’s features help to monitor, connect and secure services.
Rancher is a complex stack for teams that adopt containers. It combines everything the organization needs to adopt and run in production. As it was built on Kubernetes it allows DevOps teams to test, deploy and manage the application in a lightweight framework

Overview of Kubernetes Deployment through Istio

Kubernetes also known as K8s is system which helps to automat

e the process of deployment and containerized applications management
Istio extends Kubernetes with Envoy service proxy for establishing a programmable and application aware network.
With Kubernetes and olden workloads, Istio makes universal traffic management, security and telemetry to deployment

What are the best features of Istio and Rancher

• Service Mesh
• It has ways Ways to control data sharing between different parts of an application
• Secure communication between service to service
• Load Balancing is automatic for http
• Control in traffic behaviour
• TLS encryption, authorization and authentication tools are available to protect data and services
• Observability – Monitoring, Logging, Tracing

Features of Rancher

• The users can deploy an entire multi-container clustered application from the application catalog with a single click of a button
• Managing of deployed applications by automatically upgrading to newer versions
• It contains the distribution of container orchestration like Docker swarm, Mesos and Kubernetes
• Infrastructure services include networking, storage, load balancer, and security services
• Users interact with ranchers using a command-line tool called rancher-compose. Users interact with ranchers using a command-line tool called rancher-compose. User can deploy multiple services and containers on Rancher infrastructure depending on Docker compose templates. The rancher-compose tool also supports the docker-compose.yml file format
• Interactive UI for managing tasks and maintaining clusters
