Multi-tenant software publisher architecture

Problem: a software publisher managed each client in a separate instance (30 instances), making updates and maintenance extremely costly. Solution: redesign to a secure multi-tenant architecture (PostgreSQL schema isolation, RBAC, per-tenant encryption). Progressive migration of 30 instances. Result: infrastructure costs reduced by 60%, update deployment in 1 operation instead of 30.
