Preface

What is Apache ActiveMQ Artemis?

Apache ActiveMQ Artemis is an open source project to build a multi-protocol, embeddable, very high performance, clustered, asynchronous messaging system.
Apache ActiveMQ Artemis is an example of Message Oriented Middleware (MoM). For a description of MoMs and other messaging concepts please see the Messaging Concepts.

Why use Apache ActiveMQ Artemis? Here are just a few of the reasons:

100% open source software. Apache ActiveMQ Artemis is licensed using the Apache Software License v 2.0 to minimise barriers to adoption.
Apache ActiveMQ Artemis is designed with usability in mind.
Written in Java. Runs on any platform with a Java 11+ runtime, that's everything from Windows desktops to IBM mainframes.
Amazing performance. Our ground-breaking high performance journal provides persistent messaging performance at rates normally seen for non-persistent messaging, our non-persistent messaging performance rocks the boat too.
Full feature set. All the features you'd expect in any serious messaging system, and others you won't find anywhere else.
Elegant, clean-cut design with minimal third party dependencies. Run ActiveMQ Artemis stand-alone, run it in integrated in your favourite Java EE application server, or run it embedded inside your own product. It's up to you.
Seamless high availability. We provide a HA solution with automatic client failover so you can guarantee zero message loss or duplication in event of server failure.
Hugely flexible clustering. Create clusters of servers that know how to load balance messages. Link geographically distributed clusters over unreliable connections to form a global network. Configure routing of messages in a highly flexible way.
