The document discusses vertical slice architecture as an alternative to traditional n-tier architectures. Vertical slice architecture organizes code into classes that each handle a single request from the UI to the database rather than separating layers. This keeps code simple, easy to test, and allows the application to be more easily divided and worked on in parallel.

• User.cs
• UserController.cs
• UserService.cs
• UserRepository.cs

17. ¿Por que Vertical Slice Architecture?
• Código sencillo
• Código fácil de probar
• Separación de tests
• Aplicación fácil de dividir
