In the previous article, we saw how to install and use the Broker MQTT Mosquitto on a Raspberry Pi 3 (or some other system). The advantage of owning your own Broker is to keep your data “at home”. It is however possible to publish / subscribe data from connected objects using an online Broker.

8 Brokers MQTT in the Cloud

Online Brokers are not yet very numerous but at least 4 of them will allow you to start the realization of your connected objects. ThingStudio is clearly the most advantageous at the moment because totally free (and without limitations) for the Makers, Hackers and Designers. It joins the same free-of-charge strategy for individuals, students (and small businesses) as Autodesk with fusion360.

Finally, you will definitely find DIoTY in your research. DIoTY seems free and provides an application on iOS and Android (or rather a webapp developed with the ionic framework) to connect your connected objects. I prefer to stay away from this service at the moment because registration seems to me dubious since a gmail account.

5 OnlineMQTT Brokers  for Testing

You can also do some online testing on some Brokers. Be careful, however, not to publish anything sensitive. Topics are accessible by anyone.
