In computer science, message queues and mailboxes are software-engineering components used for interprocess communication, or for inter-thread communication within the same process. They use a queue for messaging – the passing of control or of content. Group communication systems provide similar kinds of functionality.

So one part of a system puts a message into a queue for another part to read from, and then act upon. The asynchronous nature means that each side is otherwise independent from the other, and does not wait for a response. That independence is an important part of the nature of the system though – and we’ll see later how some of the more advanced functionality for our software of choice here can give some extraordinary flexibility to what can be done.
