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.

Broker	Free offer	Free with limits
ThingMQ	In the free offer the topics are not protected
ThingStudio	Free for Makers, Hackers and Designers	X
cloudMQTT	Free up to 10 connections (10 Kbps), then from $ 19/month for 100 connections	X
IBM Bluemix	Free up to 375 GB / hour / runtime (3 runtime maximum)	X
Heroku	Free with Cute Cat offering up to 10 customers connected, then from $ 19 / month	X
Hivemq	Paying (price on request)
Microsoft Azure IoT	Free if you have an Azure account. Integration with the SDK Microsoft Azure IoT
MQTT.io	Service still under development

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.

Broker	Server	Ports	Websocket
Mosquitto	iot.eclipse.org	1883 / 8883	n/a
HiveMQ	broker.hivemq.com	1883	8000
Mosquitto	test.mosquitto.org	1883 / 8883 / 8884	8080 / 8081
mosca	test.mosca.io	1883	80
HiveMQ	broker.mqttdashboard.com	1883

You can try MQTTRoute ( https://www.bevywise.com/mqtt-broker/ ) which works with all standard MQTT Clients and at the same time can be customised to store data to any back end Big data engine or application. It has a ready to use Connectors( https://github.com/bevywise-networks ) which is a open source to customise. It can be hosted on.
