Multi-tenancy is at the heart of every SaaS product, but choosing the right model is rarely straightforward. Should you use a single shared database, a schema-per-tenant, or a database-per-tenant approach? And how do you balance cost, complexity, compliance, and scalability as your application grows? In this session, we’ll explore the architectural patterns for multi-tenancy in .NET applications, highlighting when each approach makes sense—and when it doesn’t.

Going beyond the basics, we’ll dive into real-world SaaS challenges: onboarding new tenants, handling custom features, managing thousands of tenant databases, and dealing with “noisy neighbors.” You’ll learn the trade-offs behind different models, operational pitfalls to avoid, and practical lessons on evolving your architecture as your product matures. Whether you’re starting a SaaS project or scaling one, this talk will equip you with the knowledge to make multi-tenancy a strength rather than a bottleneck.
