Is MQTT scalable?

Specifically, an MQTT broker receives messages published by clients, filters the messages by topic, and distributes them to subscribers. Using MQTT brokers to enable the publish/subscribe (pub/sub) communication model helps make MQTT a highly efficient and scalable protocol.

How many clients can a MQTT broker handle?

From vertical scaling we achieved 200k concurrent connections with one message broker and this is the maximum limit we can get from single software message broker. To achieve greater than one million concurrent connections we deployed 6 message brokers each can handle 200k simultaneous connections.

Can MQTT client connect to multiple brokers?

A MQTT bridge lets you connect two MQTT brokers together. They are generally used for sharing messages between systems. A common usage is connect edge MQTT brokers to a central or remote MQTT network. The Mosquitto broker (server) can be configured to work as an MQTT bridge.
