MVC (model-view-controller) is a well-known paradigm for designing applications. Ruby on Rails was one of the first Web frameworks to use MVC, basically forcing us to use MVC in order to create a Web application. MVC works great at first, but does it work over time? As our applications grow in size and complexity, does MVC still make sense? In this talk, Peter Harkins describes the sorts of problems that MVC-based applications can encounter as they grow and age — and the types of solutions that you can apply to your code, in order to make it work better, and become easier to maintain.
