Mule is a lightweight Java-based enterprise service bus (ESB) and integration platform that allows developers to quickly and easily connect applications to exchange data. It enables integration of existing systems regardless of technology by supporting standards like JMS, Web Services, JDBC, and HTTP. Mule provides capabilities for service creation and hosting, service mediation to shield services from different message formats and protocols, and message routing, filtering, aggregation and resequencing based on content and rules. It also allows for data transformation across varying data formats and transport protocols.

 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
