Building Scalable And Secure SaaS Applications With PostgreSQL

Multi-tenancy in SaaS apps offers reduced costs, improved scalability & enhanced security. Use single database instance, implement row-level security (RLS) & partitioning for optimal performance.

Building multi-tenancy in PostgreSQL for SaaS applications can be achieved through several approaches, each with its own advantages and trade-offs. Here are the main strategies for implementing multi-tenancy in PostgreSQL:
