Why This Topology Works

Tenant context is resolved at the gateway, ensuring schema-level isolation in PostgreSQL. Batch workers run per-tenant reports off read replicas without impacting live traffic.

Scaling Notes

Per-tenant schema keeps data isolated. Redis caches RBAC decisions. Batch workers auto-scale based on report queue depth. S3 stores generated PDFs.

Observability

Track queries per tenant, batch job duration, cache hit rates. Alert on schema drift between tenants.
