Apache Artemis
Apache Artemis is a self-hosted, multi-protocol message broker for messaging applications.
What Apache Artemis is
Apache Artemis is a self-hosted, multi-protocol message broker for messaging applications. It supports AMQP 1.0, MQTT 3.1, 3.1.1 and 5, STOMP 1.0, 1.1 and 1.2, OpenWire, and its Core protocol. Client support includes Jakarta Messaging 3.1 and JMS 2.0 and 1.1, with client implementations and JNDI. The project says clients are available in Java, JavaScript, C, C++, Python, .Net, and other languages.
Flexible clustering can distribute load, while high availability can use shared storage or network replication. Persistence options include Linux AIO, memory-mapped storage, Java NIO, and JDBC, and asynchronous mirroring is available for disaster recovery. Security is enabled by default, with role-based permissions, authentication managers, and SSL transport encryption. The project provides scripts to help create Docker images. Its free plan is billed under Apache License 2.0 and requires Java 17 or later. The download page provides SHA-512 checksums and ASC signatures and recommends verifying downloaded files.
