Building Multi-Tenant ASP.NET Core Applications: Best Practices and Real-World Solutions
#1about 4 minutes

Understanding the fundamentals and benefits of multi-tenancy

Multi-tenancy is an architectural approach for SaaS applications that offers cost efficiency, a consistent user experience, and easier scalability.

#2about 3 minutes

Navigating the common challenges of multi-tenant architecture

Building multi-tenant systems requires solving key challenges like data isolation, tenant-specific customization, noisy neighbors, and heightened security risks.

#3about 2 minutes

Choosing the right deployment model for your application

A hybrid deployment model combining a shared application with both shared and dedicated databases offers the most practical and flexible solution.

#4about 3 minutes

Identifying the active tenant from incoming web requests

The active tenant can be resolved from a request using various methods like user claims, query strings, URL routes, headers, cookies, or subdomains.

#5about 7 minutes

Automating data isolation with EF Core Global Query Filters

Use an IMultiTenant interface and EF Core's Global Query Filters to automatically apply tenant ID filters to all database queries, preventing data leaks.

#6about 2 minutes

Managing dynamic tenant-specific database connection strings

Support tenants with dedicated databases by storing their connection strings in a master table and dynamically resolving them at runtime.

#7about 2 minutes

Changing the active tenant context for background jobs

A disposable pattern allows you to safely switch the active tenant for background processes and ensures the original context is restored afterward.

#8about 3 minutes
