WebSphere Enterprise Service Bus

WebSphere Enterprise Service Bus (WESB), one of the WebSphere Business Process Management products, is the ESB portion of WebSphere Process Server and is one of the products in WebSphere, one of the brands in the IBM Software Group.

WESB provides runtime connectivity between apps in production. WESB is built on WAS and implements SCA and SDO. Its corresponding development tooling is WebSphere Integration Developer.

I have a WBPM WPS WID thread on my blog.

WebSphere Learning Resources lists places to learn about WebSphere products, including WESB.
