Rails as a piece of birthday cake

Ruby on Rails, as a framework, follows the Model-View-Controller design pattern. Three core elements, like the number of layers in a traditional birthday cake, are enough to “cook” web applications. However, in the long haul, the Rails “cake” more often resembles a crumble cake with layers smeared and crumbs (bugs) scattered all around the kitchen (codebase).

Similarly to birthday cakes, as the application grows, adding new layers is easier to do than increasing the existing layers in size.

How to extract from, or add new layers to a Rails application? What considerations should be taken into account? Why is rainbow cake the king of layered cakes? Join my talk to learn about the Layering Rails approach to keep applications healthy and maintainable.
