IBM WebSphere ESB provides an Enterprise Service Bus for IT environments built on open standards, SOA, messaging and Web services technologies of WebSphere Application Server. WebSphere ESB is a Java centric ESB that has strong integration with Web services-based connectivity and service-oriented integration. WebSphere ESB inherits the high availability and failover capability of the WebSphere Application Server, Network Deployment edition.
WebSphere ESB supports a wide variety of protocols such as JMS, MQ, EJB, WebServices, REST, HTTP etc. Formats that are supported include XML, Text, delimited, COBOL, etc. The development workbench for creating mediation flow in WebSphere ESB is called WebSphere Integration Developer. WebSphere Integration Developer builds on top of an Eclipse workbench. You can develop the mediation flows with the graphical editor by dragging and dropping primitive nodes. WebSphere ESB has many built-in nodes that support different types of operation such as data transformation, routing, filtering, database lookup, endpoint lookup, etc. You can perform all the development, unit testing and debugging in the WebSphere Integration Developer workbench. It contains a complete unit test environment which is a real WebSphere ESB runtime server.
WebSphere ESB Registry Edition provides both the ESB function and the service registry and repository function.
Famous quotes containing the words web and/or sphere:
“For us necessity is not as of old an image without us, with whom we can do warfare; it is a magic web woven through and through us, like that magnetic system of which modern science speaks, penetrating us with a network subtler than our subtlest nerves, yet bearing in it the central forces of the world.”
—Walter Pater (1839–1894)
“It is in the nature of allegory, as opposed to symbolism, to beg the question of absolute reality. The allegorist avails himself of a formal correspondence between “ideas” and “things,” both of which he assumes as given; he need not inquire whether either sphere is “real” or whether, in the final analysis, reality consists in their interaction.”
—Charles, Jr. Feidelson, U.S. educator, critic. Symbolism and American Literature, ch. 1, University of Chicago Press (1953)
