Cloud Migration: The 6R’s in Modern Cloud Migration Strategies

Over the past couple of years, we have observed most organizations have started migrating their infrastructure and applications onto the cloud server to make their data securely accessible and keep their business operation continuous. Usually, these migrations are complex and done in incremental methods customized with the organizations' pre-defined goals and carried out with internal and external IT teams by first understanding and defining the end goals of the organizations.

Let’s know what is Cloud Migration Strategy?

A cloud migration strategy is a planning and defining process an organization adopts to migrate its application and data from an on-premises server to the cloud server. It is most important for an organization's IT team to validate and adopt a suitable strategy to achieve most of the benefits of the cloud-based architecture.

Let's get some deep dive into the 6R's of modern cloud migration strategies, which will continue to stay in trend beyond 2022.

1. Re-hosting (Commonly known as “Lift and Shift”)

In this cloud migration strategy, the organization's application and data is lifted from the on-premises and hosted in the cloud server without making any extra changes. This strategy is usually adopted when there is no requirement for optimizing their applications and in the extensive short-term goals for optimizing their business process. In this strategy, organizations save a lot of costs involved in the software development life cycle and generate faster ROI.

2. Replatforming (Optimized variation of Lift and Shift)

In this cloud migration strategy, the organization makes further adjustments to optimize the application and data for the cloud server by keeping the core architecture untouched. This strategy is adopted when the organization needs a customized and requirement-centric application keeping long-term as a goal. In this strategy, the organization can optimize the responsiveness and speed of the system.

3. Repurchasing

This is a complete revamping of the application or data from the legacy desktop version to the new agile SaaS bases Version. In this cloud migration strategy the organization might have to invest for a new modern SaaS developers to re-architect the entire application on new cloud platform. This method is most cost-effectiveness option for origination in long run.

4. Refactoring (Commonly known as Re-architecting)

This is the migration strategy adopted by the organization that has an application that is not scalable with the cloud environment. For such applications or data, the organization has to rebuild the entire application from scratch by making it auto-scalable with serverless computing. This strategy is only adopted when the organization has a lot of block dots within the application and has a long-term vision to make the compatible friendly with further versions.

5. Retaining ( Also known as “Hybrid Cloud Migration”)

The name Hybrid cloud migration implies this strategy involves maintaining the application on both cloud server and legacy infrastructure. Organizations adopt this strategy with strong complaints or other regulatory constraints with their stand-alone workloads or data. For this, the required stand-alone workload or data is kept untouched and maintained on the previous infrastructure, and other components are migrated and hosted in the cloud environment.

6. Retiring

This is the most common cloud migration strategy adopted by organizations if they have a heavy legacy application but only require a few components for their day-to-day business functions. In this strategy, the application's unnecessary and complex components are identified and completely retired from the entire organization's systems. This strategy will make the application lightweight and less complex. By this, the organization can save a lot of costs involved in storage, licensing, and backup for the unused or unnecessary components of the application.
