MQTT is a messaging protocol that is popularly used by IoT devices. It is designed to be lightweight and efficient which is perfect for low powered devices.
However, for MQTT to work, it relies on what is called an MQTT broker. These brokers act as like the middleman for any MQTT message. It can receive new message on topics and then allow them to be retrieved by subscribers.
One of the easiest ways to get an MQTT broker up and running is by using a Docker container.
