- Scalability: If you need multiple servers to handle large traffic, the cloud has plenty available, just a click away.
- Profitability: Ditch expensive local infrastructure maintenance. Cloud offers a pay-as-you-go model, like renting a cloud-powered kite instead of buying your own stable.
- Innovation: Embrace the latest cloud technologies and unlock new opportunities, like using a cloud-powered telescope to scan future business opportunities.
With these riches at your fingertips, who wouldn’t want to join the cloud migration frenzy? However, navigating the landscape of the seven Rs without understanding their strengths and limitations can lead to detours and missed opportunities. In the next section, we’ll dig deeper into each R, unpack their individual characteristics, and equip you to chart the optimal course toward your cloud kingdom.
The Seven R’s of Cloud Migration
The Seven R’s represent different 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
- Repositioning (lifting and moving): This fast and cost-effective option involves the direct migration of applications to the AWS cloud infrastructure without significant architecture changes. Think of it as simply moving your servers to a cloud data center, taking advantage of its scalability and resilience. However, this approach can limit the long-term agility and optimization potential of the cloud.
- Move: If you’re looking for AWS-specific features or multi-cloud flexibility, moving your applications to another cloud platform might be ideal. This approach requires careful planning and compatibility testing, but opens the door to specialized services or cost optimization opportunities.
- Replatform: When existing architecture precludes cloud optimization, replatforming applications allow you to take full advantage of cloud native principles. This approach involves significant rework to unlock advanced scalability, elasticity, and resiliency. However, it requires significant resources, expertise and planning.
- Refactor: For applications where forward-looking agility is key, 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.
- Redemption: Instead of extensive re-platforming, you can repurchase legacy applications for cost-effective cloud-native equivalents that offer similar functionality. This approach streamlines maintenance, provides modern features, and leverages the inherent benefits of cloud architecture.
- In retirement: This AWS cloud migration strategy targets legacy, underutilized, or incompatible applications. Decommissioning these applications frees up resources and simplifies your IT infrastructure while reducing maintenance costs and potential security vulnerabilities.
- Keep: For stable and compliant applications, keeping them on-site ensures operational continuity and minimizes disruptions. This approach avoids unnecessary migration efforts and allows you to focus cloud resources on strategic priorities.
By understanding the strengths and limitations of each RA, you can confidently choose the most appropriate migration strategy for each application in your portfolio. Note that a hybrid approach is often optimal, tailoring specific R’s to different applications for successful cloud adoption.
