Quick Answer
Rollback strategies: blue-green makes rollback instant (switch traffic back to blue). Canary rollback means reducing new version traffic to 0. Rolling rollback: Kubernetes rolls back the Deployment to previous ReplicaSet version (kubectl rollout undo). Feature flags let you disable a feature without redeploying. Keep DB migrations backwards-compatible to allow code rollbacks without data loss.
