Cloud Migration Services and Strategy (2024)

FAQs

What are the 5 cloud migration strategies? ›

There are seven cloud migration strategies: rehosting, redeployment, repackaging, refactoring, repurchasing, retiring, and retaining. These were originally called the “5 Rs” by Gartner, and later expanded to “7 Rs”.

The 6 Rs of cloud migration—re-host, re-platform, repurchase, retain, retire, and re-factor—can help you to determine clear paths for your migration. You can look at each “R” as a separate migration strategy. But that does not mean that the 6 Rs are definitive or the only way to develop your migration plan.

The decision to migrate applications to the cloud is often accompanied by various considerations such as costs, efficiency, and modernization. To simplify the process and to make sure it's effective, it's useful to adhere to the "4 Rs" strategies: Re-host, Re-platform, Re-factor/Re-architect, and Replace.

Phase 1: Prepare. Phase 2: Plan. Phase 3: Migrate. Phase 4: Operate and optimize.

A cloud migration strategy is the plan an organization makes to move its data and applications from an on-premises architecture to the cloud.

Once the decision has been made that cloud is the best option to solve the business challenges you face (and it may not be), there are three phases of moving to the cloud: planning, mid-shift, and go-live.

The 7 cloud migration strategies are: rehost, relocate, replatform, refactor, repurchase, retire, and retain. These strategies provide a roadmap for determining the best approach to moving applications and data from on-premises infrastructure to the cloud.

Businesses adopt cloud migration strategies for better scalability, availability, and faster deployment of software services. The costs of maintaining an on-premises data center are too high for most businesses to manage compared to the cost of services at public cloud hosts like Google, AWS, and Microsoft Azure.

What makes a cloud migration successful? ›

A solid cloud migration plan is a sound foundation for a successful move. This plan should be the roadmap of your migration process, and it should take into account all artifacts, architecture, timelines, dependencies, support, and contingencies.

Migrating Applications to the Cloud: Rehost, Refactor, Revise, Rebuild, or Replace?

Human migration is when people move from one place to another, and they do so for many reasons. Six types of migration are internal emigration, international migration, emigration, immigration, rural-urban migration, and counter-urbanization.

However, a big part of this strategy is deciding the main method of migration, which can be described using the 7Rs – rehost, replatform, refactor/rearchitect, repurchase, relocate, retain, and retire. How you decide to handle key applications and data will dictate and shape the rest of your cloud strategy.
