Cloud Migration — 7R Strategy¶
Cloud Migration7RStrategyAssessment 5 min read
Rehost, Replatform, Refactor, Repurchase, Retire, Retain, Relocate. Assessment and planning.
7R Framework¶
- Rehost — lift & shift, fastest
- Replatform — minor adjustments (managed DB, containers)
- Refactor — rebuild as cloud-native
- Repurchase — switch to SaaS
- Retire / Retain / Relocate
Assessment¶
1. Discovery — inventory, dependencies, performance baseline
2. Analysis — 7R decision per app, TCO, risk
3. Wave Planning — group into waves, quick wins first
Strangler Fig¶
The safest refactoring approach: new features as cloud-native, proxy routes traffic, the monolith is gradually “strangled”.
Summary¶
Migration = marathon. Assessment → waves → replatform as a pragmatic compromise.
