mqtt - Cluster forming with Mosquitto broker

Question

I am using Mosquitto broker to implement MQTT protocol. But I am unable to find how clustering can be done in case of mosquitto brokers. Also is there any limitation on number of clients those can be served with one broker.

Answer 1

You can't do clustering with mosquitto.

Some other MQTT brokers out there which support clustering, including HiveMQ. HiveMQ has an elastic cluster ability with auto discovery and a distributed masterless architecture and works very well on cloud providers like AWS or Azure.

You can see a full list of all brokers which support clustering here.

Disclaimer: I'm a developer of HiveMQ, so this answer may be biased.
