Mule is a lightweight Java-based enterprise service bus (ESB) and integration platform that allows developers to connect applications together quickly and easily, enabling them to exchange data. Mule enables easy integration of existing systems, regardless of the different technologies that the applications use, including JMS, Web Services, JDBC, HTTP, and more.

The key advantage of an ESB is that it allows different applications to communicate with each other by acting as a transit system for carrying data between applications within your enterprise or across the Internet. In addition it supports API driven development by offering full support and integration of RAML modelling language.

Mule main capabilities includes:

  • Service creation and hosting — expose and host reusable services, using Mule as a lightweight service container
  • Service mediation — shield services from message formats and protocols, separate business logic from messaging, and enable location-independent service calls
  • Message routing — route, filter, aggregate, and re-sequence messages based on content and rules
  • Data transformation — exchange data across varying formats and transport protocols
