RabbitMQ is an open-source message broker that offers a reliable, highly available, scalable, and portable messaging system.


Message queues provide an asynchronous communications mechanism in which the sender and the receiver of a message do not contact each other. 


Nor do they need to communicate with the message queue simultaneously. When a sender places a message onto a queue, it is stored until the recipient receives them.
