AWS Migration Strategies
This lesson is part of AWS · All levels
Summary
AWS compiled a migration strategy known as the 7 Rs: Rehost, Replatform, Refactor, Repurchase, Retire, Retain, and Relocate. The choice of strategy for each application is based on business value, complexity, and the desired level of modernization. Not all applications must be migrated, some may be retired or retained first.
Key points
- Rehost: lift-and-shift without change (fastest)
- Replatform: limited changes such as moving to RDS
- Refactor: architectural redesign towards cloud-native
- Retire and Retain: retire applications or delay migration
- Repurchase: switching to SaaS products
