Architectural logic: Versioning stores multiple versions per key; overwrite creates new version; delete adds delete marker. Use cases: Recovery (copy prior version over current); audit; accidental overwrite protection. Trade-off: Storage cost increases; lifecycle can transition old versions. Best practice: Lifecycle for old versions; MFA delete for critical; Object Lock for compliance.
Red Flag: Versioning without lifecycle—cost explosion. Pro-Move: 'We version critical buckets; lifecycle moves old versions to IA after 90 days—recovery and cost balanced.'
