Publish-Subscribe is a messaging pattern that works as follows: a group of consumers subscribe to events of a given topic and are notified whenever an event of that topic arrives. When an event is published into a topic channel, the channel delivers a copy of the message to each of the output channels. The advantage of this is we can decouple the consumers from the producers.
