High level Architecture of ESB

When client send a message to wso2 ESB with any transport like HTTP, Mail, JMS, FIX then ESB will decide what is the content of the message (like text/xml, application/xml, JSON) and select a message builder according to the content type. So message builder take a specific content type message and build a SOAP/XML message which can be use inside ESB. If there are quality of service mechanism defined then it will go through that mechanism and send it to the mediation engine.

Mediation engine transformation, proxy service will happen. After transforming the message, need to send from ESB to back end service. And also the format of the outgoing message will be defined inside ESB.
