Which migration strategy refers to redesigning application architecture for optimal cloud compatibility?

• A. Rehost
• B. Refactor
• C. Rearchitect
• D. Retire

Answer: (C)

The migration strategy that refers to redesigning application architecture for optimal cloud compatibility is rearchitecting. This approach involves making significant changes to an application's design to fully leverage cloud-native features, such as scalability, efficiency, and resilience. By rearchitecting, an organization can take advantage of the unique capabilities offered by cloud platforms, such as microservices architecture, serverless computing, and self-healing services. This strategy is particularly beneficial when an application is not well-suited for the cloud as-is. It allows for the integration of modern cloud practices and tools while often resulting in improvements in performance and maintainability. Rearchitecting enables applications to better utilize cloud resources and align with operational methodologies such as DevOps, enhancing both deployment speed and agility. Other strategies like rehosting, which typically involves moving an application to the cloud without major changes (also known as "lift and shift"), and refactoring, which involves making limited modifications for cloud optimization, do not entail a complete redesign of the architecture. Retiring refers to discontinuing applications that are no longer needed, rather than modifying them for cloud use.
