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
