@oikibun Thanks for the suggestion.

Is there a particular cloud that you are interested in using? As we'd have to check what is supported by each of the clouds, e.g. AWS, Azure, Cumulocity IoT?

If you're talking about Cumulocity IoT, then we have to check if certificate based authentication is supported when using MQTT over websockets.
