Microsoft Certified: Azure Solutions Architect ExpertDesign infrastructure solutionsMedium
A large enterprise plans to migrate hundreds of on-premises applications to Azure. The migration strategy needs to account for varying application complexities, interdependencies, and business criticality. The company seeks a structured approach to categorize and prioritize these migrations. Which migration strategy framework should the company adopt to guide this process?
- AThe five pillars of the Azure Well-Architected Framework
- BThe six Rs of cloud migration (Rehost, Refactor, Rearchitect, Rebuild, Replace, Retire)
- CThe four phases of the DevOps lifecycle (Plan, Develop, Deliver, Operate)
- DThe three stages of the cloud adoption framework (Strategize, Plan, Ready)
Show answer & explanationAnswer & explanation
Correct answer: B. The six Rs of cloud migration (Rehost, Refactor, Rearchitect, Rebuild, Replace, Retire)
The six Rs of cloud migration provide a structured framework to categorize and prioritize applications based on their migration approach. This helps in making informed decisions about how each application will move to the cloud, considering its complexity and business value.
Why the other options are wrong
- A. The Azure Well-Architected Framework focuses on operational excellence, security, reliability, performance efficiency, and cost optimization, not migration strategies.
- C. The DevOps lifecycle focuses on software development and operations practices, not the initial migration strategy for moving applications to the cloud.
- D. The Cloud Adoption Framework provides guidance for the entire cloud journey, but the 'six Rs' specifically address the migration strategy part.

- Retire
Memory trick: To migrate, remember the 'Six R'outes.
