MVC(Model-View-Controller) 架構適合於大型系統，它可以分層且可以在實體層面切割為不同的機器或服務，只要彼此間具有適當的通訊協定即可。MVVM(Model-View-ViewModel) 架構適合像 XAML 這種與程式碼無關 (code ignorance) 的使用者介面設計，只要 View 中下特定的指令與 ViewModel 串接，就可以享有 ViewModel 溝通的功能，而 ViewModel 只需做一些特別的介面實作，即可平順的和 View 溝通。MVP(Model-View-Presenter) 架構適合集中由程式碼決定 View 動作的應用程式，而 View 只需要實作特定的介面即可，不需要太複雜的工作，但 Presenter 則可能會受限於 View 介面的動作，而無法做更進一步對 View 的控制。
