Pub/Sub Messaging is at the core of real-time functionality in web, mobile, and Internet of Things applications. To name a few general uses, it enables you to stream data, communicate bi-directionally, broadcast, and signal devices. Really, the use cases are endless.

But in the simplest terms, it revolves around publish and subscribe, where messages are sent from a a publisher to any number of subscribers.

  3. Subscribe to a channel
  4. Publish to that channel

And that’s it!
