Cloud Migration Strategy: The 7 Rs Explained for Business Leaders
Short answer The 7 Rs are the seven ways to move each application to the cloud: retire, retain, rehost, relocate, repurchase, replatform and refactor. Do not pick one strategy for the whole estate. Decide per application based on its business value and technical condition, retire what you can, move most applications with rehost or replatform, and refactor only what differentiates the business. 7…
The "7 Rs" are the seven strategies for migrating applications to the cloud, each suited to specific types of applications based on their business value and technical condition. These strategies include retiring unused systems, keeping low-value applications as-is, rehosting applications with minimal changes, relocating virtualized applications, repurchasing software as a service (SaaS), re-platforming applications with targeted optimizations, and refactoring applications to use cloud-native features.
It is crucial to choose a strategy per application rather than applying a one-size-fits-all approach. The decision should be based on factors such as business value, technical health, risk and compliance, timing, and cost considerations. Common mistakes in cloud migration include applying the same strategy to all applications, failing to retire unused systems, or treating migration as the end goal without addressing post-migration operating practices.
To execute a successful cloud migration, businesses should assign one of the 7 Rs to each application, plan migration waves based on dependencies, and establish a cost control strategy from the outset.
