Multi-tenancy is an architectural approach for SaaS applications that offers cost efficiency, a consistent user experience, and easier scalability.
Building multi-tenant systems requires solving key challenges like data isolation, tenant-specific customization, noisy neighbors, and heightened security risks.
A hybrid deployment model combining a shared application with both shared and dedicated databases offers the most practical and flexible solution.
The active tenant can be resolved from a request using various methods like user claims, query strings, URL routes, headers, cookies, or subdomains.
Use an IMultiTenant interface and EF Core's Global Query Filters to automatically apply tenant ID filters to all database queries, preventing data leaks.
Support tenants with dedicated databases by storing their connection strings in a master table and dynamically resolving them at runtime.
A disposable pattern allows you to safely switch the active tenant for background processes and ensures the original context is restored afterward.
A blue-green deployment with a load balancer is the recommended strategy for migrating tenant databases with minimal downtime.
