In AWS migration guidance, what do the '6 R's' describe?
A.Six AWS regions recommended for disaster recovery
Regions aren't part of the migration-strategy framework.
B.Six common application migration strategies — rehost, replatform, repurchase, refactor, retain, retire
Correct — the six migration strategies every migration plan references.
C.Six stages of the Cloud Adoption Framework
CAF is a separate organizational-readiness framework with six perspectives, not the 6 R's.
D.Six Well-Architected pillars
Well-Architected also has six pillars, but that's a different framework.
Why this answer
The 6 R's are migration strategies: rehost (lift-and-shift), replatform (lift-tinker-shift), repurchase (move to SaaS), refactor (re-architect), retain (keep on-prem), retire (decommission).
