**Publish-subscribe pattern** is all about **INDIRECT COMMUNICATION** between two entities.
These two entities don't know about each other meaning they **don't hold a reference to each other**. By they I mean publisher and subscriber of course. Thanks to that these two entities are **decoupled** and can talk to each other via subscriptions.
