EMQX updated to version 5.0

2Smart Cloud uses the open-source MQTT broker EMQX. The development team of this solution released the stable version 5.0 in July 2023, which our platform switched to in this release.

The latest version of EMQX includes many of the newest features, detailed in the developer’s blog. Key among them is that the broker now supports up to 100 million concurrent device connections by using the latest Mria extension for Erlang’s Mnesia database. The Mria architecture allows for greater horizontal scalability and adaptability to increasing demand in IoT networks.

The update also includes improved security management, the world’s first implementation of MQTT over QUIC, bidirectional data flow through a more powerful rule engine, and a more intuitive user experience.
