Architectural logic: Lake Formation = governance layer over data lake. Benefits: Centralized table/column permissions; Glue Catalog integration; row/column-level security; audit. Why: IAM alone is coarse; Lake Formation enables fine-grained access (e.g., analyst sees only non-PII columns). Cost: No extra for Lake Formation; Glue/catalog costs apply. Best practice: Use for fine-grained access; tag-based policies for scale; enable for new DBs/tables.
Red Flag: Granting S3 bucket-wide access when column-level suffices. Pro-Move: 'We use Lake Formation for PII—analysts get filtered columns; audit logs every access—compliance ready.'
