Architectural logic: Versioning stores multiple object versions per key; PUT creates new version; DELETE adds delete marker. Use cases: Recovery, retention, audit. Trade-off: Storage cost; lifecycle rules for old versions. Best practice: Enable for critical buckets; lifecycle to archive; MFA delete for extra protection.
Red Flag: Versioning without understanding storage cost impact. Pro-Move: 'We version PII buckets; lifecycle transitions old versions to Glacier after 180 days—compliance and cost managed.'
