The seven R’s of cloud migration

The seven R’s represent distinct migration strategies with varying degrees of complexity, speed, and long-term impact on your application portfolio. Let’s explore each R in detail, highlighting its purpose, suitability, and potential limitations:

Source: AWS

1. Rehost (Lift and Shift): This rapid and cost-effective option involves directly migrating applications to the AWS cloud infrastructure without significant architectural changes. Think of it as simply relocating your servers to a cloud data center, leveraging its scalability and resilience. However, this approach may limit long-term agility and cloud-native optimization potential.

2. Relocate: If you seek specific AWS features or multi-cloud flexibility, relocating applications to a different cloud platform might be ideal. This approach requires careful planning and compatibility testing but opens doors to specialized services or cost optimization opportunities.

3. Replatform: When existing architecture impedes cloud optimization, replatforming applications allows you to fully utilize cloud-native principles. This approach involves significant reworking to unlock advanced scalability, elasticity, and resilience. However, it demands substantial resources, expertise, and planning.

4. Refactor: For applications where future-proof agility is crucial, refactoring involves building them completely from scratch, embracing serverless technologies and microservices architecture. This most comprehensive approach unlocks future potential but requires intensive resources and planning.

5. Repurchase: Instead of extensive replatforming, you can repurchase outdated applications for cost-effective cloud-native equivalents offering similar functionality. This approach streamlines maintenance, provides modern features, and leverages the inherent advantages of cloud architecture.

6. Retire: This AWS cloud migration strategy targets outdated, underutilized, or incompatible applications. Retiring these applications liberates resources and simplifies your IT infrastructure, while reducing maintenance costs and potential security vulnerabilities.

7. Retain: For stable and compliant applications, retaining them on-premises ensures operational continuity and minimizes disruption. This approach avoids unnecessary migration efforts and allows you to focus cloud resources on strategic priorities.

By understanding the strengths and limitations of each R, you can confidently choose the most appropriate migration strategy for each application in your portfolio. Remember, a hybrid approach is often optimal, tailoring specific R’s to different applications for successful cloud adoption.
