AMQP, standing for Advanced Message Queuing Protocol, is a protocol that supports a wide range of messaging patterns and offers a robust set of features. It was created by J.P. Morgan Chase in 2003. It is designed for systems that require a high level of reliability and functionality. The strength of AMQP lies in its extensive feature set. It supports a variety of message properties and delivery modes, including persistent messaging, which ensures the messages are not lost even if the broker restarts.
