Controllers keep your code organized. Controllers are responsible for handling incoming requests and returning responses to the client.

So Controllers handle HTTP requests, while Providers contains shared logic throughout the entire application and can be injected as a dependency. Examples: You can use Providers to implement a guard to handle role-based user authentication or turn it into a filter to pipe data that validates and transform values in a controller.

Modules allows code to be organized into smaller components where it can be lazy loaded to run faster in serverless environments.
