Choosing Your Messaging Protocol: AMQP, MQTT, or STOMP

MQTT_HeaderOne of the most common questions I’m asked to cover when I discuss software architecture topics is the difference between the various application messaging protocols that exist today—issues like how and why the protocols came about, and which one should be used in a particular application.

Their question is valid.

Today, application architects need to use a messaging broker to speed and scale their applications, particularly in the cloud. Even once you select your messaging middleware application, application developers need to then select the protocol. Understanding the subtle differences between them can be difficult.

Today, we will consider three of the most common and popular TCP/IP-based messaging protocols, and provide a quick summary on the advantages of each: AMQPMQTT and STOMP. Before we go on, I should also point out that all three of these protocols are supported in RabbitMQ version 3.0—something we will use as an example and come back to later.
