MQTT Broker Service Provider

For this activity, we will use Eclipse Mosquitto as our MQTT broker. Mosquitto is a renowned open-source message broker, licensed under EPL/EDL. The official Mosquitto website offers both the MQTT Broker Server and Client software for download. Additionally, the site provides an online MQTT Broker Service, which is invaluable for testing client applications.

We will utilize the free MQTT Broker Service available at for this activity. A notable advantage of this service is that there’s no requirement for registration or additional setup, making the process straightforward and user-friendly.

For those who prefer a localized solution or more control, there’s an option to download the MQTT Server software and set it up on your personal machine.
