Apache ActiveMQ
Apache ActiveMQ is an open source message broker written in Java together with a full Java Message Service (JMS) client. It provides "Enterprise Features" which in this case means fostering the communication from more than one client or server. Supported clients include Java via JMS 1.1 as well as several other "cross language" clients.[2] The communication is managed with features such as computer clustering and ability to use any database as a JMS persistence provider besides virtual memory, cache, and journal persistency.[3]
ActiveMQ is currently in major version 5, minor version 16.[1] There's also a separate product called Apache ActiveMQ Artemis which is a new JMS Broker based on the HornetQ code base which was previously owned by Red Hat, and bringing the broker's JMS implementation up to the 2.0 specification.[4]
Amazon Web Services offers a managed message broker service for Apache ActiveMQ called Amazon MQ[5]
History
The ActiveMQ project was originally created by its founders from LogicBlaze[6] in 2004, as an open source message broker, hosted by CodeHaus. The code and ActiveMQ trademark were donated to the Apache Software Foundation in 2007, where the founders continued to develop the codebase with the extended Apache community.
Technical features
ActiveMQ employs several modes for high availability, including both file-system and database row-level locking mechanisms, sharing of the persistence store via a shared filesystem, or true replication using Apache ZooKeeper. A horizontal scaling mechanism called a Network of Brokers,[7] is also supported out of the box. ActiveMQ supports a relatively large number of transport protocols, including OpenWire, STOMP, MQTT, AMQP, REST, and WebSockets.[8]
Usage
ActiveMQ is used in enterprise service bus implementations such as Apache ServiceMix[9] and Mule.[10] Other projects using ActiveMQ include Apache Camel[11] and Apache CXF[12] in SOA infrastructure projects.[13]
Benchmark
Coinciding with the release of Apache ActiveMQ 5.3, the world's first results for the SPECjms2007 industry standard benchmark were announced. Four results were submitted to the SPEC and accepted for publication. The results cover different topologies to analyze the scalability of Apache ActiveMQ in two dimensions.[14][15]
Commercial support
Apache offers limited ActiveMQ support on a volunteer basis. Commercial companies specializing in ActiveMQ are recommended for users needing more extensive support.[16]
