What is MQTT

MQTT is a so called "publish-subscribe" (pub/sub) messaging protocol.

Pub/sub is a messaging pattern where senders of messages, called publishers, do not send messages directly to specific receivers, called subscribers, but instead characterize published messages into classes without knowledge of which subscribers, if any, there may be. Similarly, subscribers express interest in one or more classes and only receive messages that are of interest, without knowledge of which publishers, if any, there are. (Ref: Rephrased from the introduction paragraph of the English Wikipedia article Publish/Subscribe Pattern)
