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.

The complete answer continues with detailed implementation patterns, architectural trade-offs, and production-grade considerations covering performance optimization and real-world examples.
