RabbitMQ is an open-source message broker software that implements the Advanced Message Queueing Protocol (AMQP). It supports multiple messaging protocols. It can be used for performing background operations and asynchronous operation.

RabbitMQ is written using Erlang programming language and it is built on the Open Telecom Platform framework.
