But isn't the central notion of an ESB the "bus" concept (as is obvious from the name).
I always interpreted this as providing the logical equivalent of a "transport" mechanism which connects every "place" (application) to every other for "passengers" (messages). I still find a lot of logic to the concept and hence to the products. Web Services today are notoriously location centric (think service endpoint URL) even though they don't HAVE to be. So I don't necessarily agree with "The power of an ESB thingy is that it provides the neutralization or standardization layer away from every application." Nor do I agree that ESB's and SOA's compete in any way.

The power of an ESB thingy is that it provides the neutralization or standardization layer away from every application. I.e. if you don't neutralize, and instead provide multiple implementation support in each client interface, that doesn't scale well. An ESB thingy lets you neuralize at a central point which allows you to do it once. It also allows you to refocus on a different interface implementation in one place as well as recombine disjoint data into a new package. Gregg Wonderly Yahoo! Groups Links Yahoo!
