Cloud MQTT is a hosted MQTT broker. The video below demonstrates how to connect the SCADASuite MQTT application to Cloud MQTT.
The demo shows a few live values from the SCADASuite Plunger Lift application that is running on the same RTU as the MQTT application being pushed to Cloud MQTT. Using slashes in the names of the values in the MQTT application allows for data to be grouped by topic (details at around 3:20 in the video).
