ASP.NET SaaS: How to Structure a Production-Ready Application
Launching a SaaS product on ASP.NET means more than writing some CRUD endpoints. Here’s how to structure the app for reliability, maintainability, and growth.
Layers, Modules, and Why They Matter
- Layered architecture: Separate data access, business logic, and presentation—from the start.
- Modularization: Split features into modules: identity, payments, admin, notifications. Each should be independently testable and interchangeable.
- Dependency injection: Leverage DI everywhere for clarity and testability.
Core Modules for SaaS
Critically, a production SaaS needs much more than auth and CRUD. You need:
- Subscription billing with real renewal logic
- Audit and monitoring
- Admin and support tooling
- Multi-tenant data isolation (if you serve B2B clients)
Hosting, Continuous Deployment, and Configuration
- Use environment-based configuration (for database, keys, external services)
- Automate deployments and database migrations
- Always run a staging environment before pushing to prod
