00 - Scalable LMS Architecture: Multi-Tenant Patterns

Designing scalable multi-tenant LMS: schema isolation, tenant routing, caching and database optimization for millions of users.

What you'll learn

• Choose the multi-tenant pattern based on your customer profile, not technology trends. Shared schema + RLS is sufficient for most SaaS LMS platforms.
• Tenant resolution is the foundation of security. Implement it as robust middleware with caching and rigorous validation.
• PostgreSQL's Row-Level Security is your best ally for guaranteeing database-level isolation without excessive application complexity.
• Event-driven architecture is essential for notifications, analytics, and all real-time features of a modern LMS.
• Citus for PostgreSQL enables horizontal scaling with minimal application changes when a single node is no longer sufficient.
