Mule, the runtime engine of Anypoint Platform, 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. It enables easy integration of existing systems, regardless of the different technologies that the applications use, including JMS, Web Services, JDBC, HTTP, and more. The ESB can be deployed anywhere, can integrate and orchestrate events in real time or in batch, and has universal connectivity.

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. Mule has powerful capabilities that include:

Service creation and hosting — expose and host reusable services, using the ESB 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
