Creating an MQTT Broker With CloudMQTT

Cloud based brokers are likely to become very popular in the future for organisations they operate over a wide geographic area.

CloudMQTT like Amazon,Azure etc provide a managed cloud based mosquitto broker.

The plans on CloudMQTT are shared plans which means that several MQTT brokers run on the same hardware.

The brokers are distinguished by the port numbers as shown in the diagram below..

Connecting to your Broker Using Python

Below I’ve shown the relevant bits of code from my script. The important thing to note is the call to the username_pw_set function. (Note: the password and username has been change for security)

broker="m21.cloudmqtt.com"
port=17363
username="toyeerbnp"
username="steve1e"
password="JUlkU47AEy86o"
client.username_pw_set(username, password)
client = mqtt.Client("Python1",clean_session=CLEAN_SESSION)
client.connect(broker,port)
