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. Neither party need knowledge of each other to communicate. In other words, pub-sub is a pattern used to communicate messages between different system components without the components knowing anything about each other’s identity. Let’s look at an implementation of Publish-Subscribe in Elixir. The full source code is provided below.

Elixir provides powerful tools and abstractions for managing concurrent processes, making it ideal for building scalable and fault-tolerant systems. Concurrency in Elixir is achieved through lightweight processes called "Elixir processes." These processes are not operating system threads
