问题 While evaluating various ESB's, I came across Apache Synapse & WSO2. In WSO2 it's mentioned that WSO2 completely uses Synapse and built on top of it. However I am not still clear what additional features does WSO2 offer over Synapse? (Apart from commercial support). One difference I could see is the web UI to manage proxy definitions, sequences creation etc. Are there any other features which WSO2 provides over Synapse? Also please share if there are any guidelines to choose between Synpase &

The web-tier just receives the request from clients and distributes to a given set of app-tier instances. Since the end-points are already defined and used by clients, I had to build the ESB proxy using the "CustomURI" approach as described here - http://achala11.blogspot.com/2012/08/access-wsdl-for-customuri-wso2-esb.html - to expose the end-point and wsdl.
