MQTT
A lightweight publish-and-subscribe messaging protocol widely used in IIoT and connected systems.
IN ONE SENTENCE
Devices publish data to topics and interested systems subscribe to those topics through a broker.
In normal English
MQTT separates data producers from consumers, making it practical for edge-to-cloud and distributed monitoring systems.
Why would I use it?
Use it when many devices or applications need flexible, efficient data distribution.
THINK OF IT LIKE…
A radio station model: publish on a channel and anyone subscribed can listen.
