Cloud Migration : Lift & Shift Approach

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

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 MarketShare

The global cloud migration services market growth is primarily driven by the rise in the adoption of hybrid cloud solutions. As the cloud computing market continues to grow, enterprises are exploring different cloud models in search of the right balance of functionality, flexibility, and investment protection

In addition, the key role of cloud migration is to host applications and data in the most effective IT environment possible, based on factors such as cost, performance, and security

For example, many organizations perform the migration of on-premises applications and data from their local data center to public cloud infrastructure to take advantage of benefits, such as greater elasticity, self-service provisioning, redundancy, and a 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. Typically, lift and shift is a minimal risk approach that can benefit workplace operations

You want to reduce risk: Lift and shift is a simpler and less risky process than other methods such as re-platforming or refactoring

Always look at the larger picture when choosing migration options. 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

To avoid bounce back, businesses require a cost-allocation strategy and clear-cut roles within their organization to monitor cloud spending. This will most likely need additional tools

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

Technical Stack:

Choosing the best cloud provider is a tough nut to crack. AWS, Azure and GCP leaders offer comprehensive solutions that include myriads of features that are necessary to develop robust and reliable applications. AWS has been on the market since 2002, which makes it the most mature product that has invested in worldwide data centers and solutions for many years. Google Cloud and Azure are relatively new, but on the other hand, they can take advantage of the experience and infrastructure of tech giants: Google and Microsoft

AWS is a public cloud, flexible and ready to meet the needs of both big and small applications. Azure is focused on the enterprise market and its flawless integrations with Microsoft 365 ecosystem are its strong value. On the other hand, Google Cloud Platform has a similar advantage – it integrates well with all the popular tools provided by Google, which means that the final choice of the cloud provider will be significantly influenced by other tools and ecosystems that are preferred by the development team
