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.
