The API pattern bind IO functionality to business functionality by binding IO state either through annotation (ie JAX) or by extending a RestfulController. As a result, the data associated IO State cannot be shared with the architectural instances because it is bound to the controller. This creates architectural cross cutting concerns not only with the functionality but also with the data. By abstracting the functionality, we can create a versioned data object for IO state that can be shared,cached,synced,reloaded on the fly for all architectural instances without having to restart any instance. This greatly improve automation, performance and flow of api applications and architecture.
