Publish/Subscribe messaging

Publish/Subscribe Messaging is a communication method used in computing where information is shared between different systems or applications. In this model, "publishers" send messages about specific topics without needing to know who will receive them. "Subscribers" express interest in these topics and receive updates when new messages are published. This setup promotes decoupled interactions, meaning publishers and subscribers can operate independently, making systems more flexible and scalable. It's commonly used in applications like news feeds, social media, and notifications, allowing users to get relevant information while preventing unnecessary communication overload.
