JBoss Fuse is an ESB (Enterprise Service Bus) that concentrates on transformation, mediation, routing of the data in different applications via both external and internal services. Fuse is an open-source that can be implemented by the OSGi (Open Source Gateway initiative). It allows functionality modules to be loosely coupled without rebooting multiple bundle versions.

It implements Apache Camel and EIPs (Enterprise Integration patterns) for creating routing solutions and integrations. With more than 140 defined endpoints JBoss Fuse allows various services instantly upon deployment. Fuse’s web and framework are dependants on the Apache CXF.
