Eclipse Amlen is a newly available message broker that focuses on publish/subscribe messaging for IoT/Web/Mobile use-cases. It has full support for the widely used MQTTv5 and MQTTv3.1.1 protocols. It is easy to set up and manage and has support for high availability pairs and clusters of brokers. Amlen is based on an initial contribution of IBM's WIoTP Message Gateway message broker (formerly called MessageSight) so it has a mature codebase with a long pedigree of use in large deployments, e.g. in the Automotive industry. Jon is the project lead for Eclipse Amlen, he is on the OASIS MQTT standards committee and has been the lead architect for IBM's Message Gateway product as well as one of the initial developers on the codebase.
