FUSE ESB is an open source, enterprise version of Apache ServiceMix. This enterprise release is tested, certified and supported.

FUSE ESB is an open source enterprise service bus (ESB) that provides a standardized methodology, server, and tools to deploy integration components, freeing architects from the dependencies that have traditionally locked enterprises into proprietary middleware stacks.

Built from the ground up to support the JBI specification (JSR 208), FUSE ESB provides a structured environment to manage and deploy the components that developers create using FUSE Services Framework and FUSE Mediation Router, as well as additional JBI-compliant components like BPEL. FUSE ESB uses FUSE Message Broker as its underlying messaging infrastructure.
