If we take the service example as "SAP", Mule as the ESB.
Mule ESB is the only enterprise service bus to be certified by SAP for SAP integration. Mule’s SAP Enterprise Connector provides bidirectional communication and works with existing SAP technologies such as:
Intermediate Documents (IDocs) Business Application Programming Interfaces (BAPIs) SAP Java Connector (JCo)
Additionally, Mule ESB provides industry-leading Cloud Connect technology, which can be used along with the SAP-certified connector to dramatically simplify integration with Salesforce’s many APIs. With Mule ESB, integration between SAP and Salesforce has never been easier.- See more at: https://www.mulesoft.com/resources/esb/sap-salesforce-integration#sthash.UBdtoUMC.dpuf
