Definition:Multi-tenant Architecture
Multi-tenant Architecture is a cloud software model where a single application instance serves multiple client organizations (tenants) securely.
Detailed Technical Explanation
Business Perspective
Drastically lowers SaaS server hosting costs and allows pushing software updates to all clients simultaneously.
Technical Perspective
Requires injecting tenant ID session filters into every database query to prevent cross-tenant data leakage.
Real-World Example
RokdaBook serving thousands of separate retail stores from a single high-availability cloud server deployment.
Common Architectural Mistakes
- ✗Cross-Tenant Data Leaks: Failing to enforce database row-level security, allowing one client to view another client's records.

Frequently Asked Questions
How to enforce tenant security?
Enforce PostgreSQL Row-Level Security (RLS) policies at the database layer so API queries strictly filter by tenant ID.
