<<Question 2: Is an ESB an Architecture or a Product? A big question in the ESB space is, "Is an ESB an architecture or a product?" On the surface, this question seems a little strange, because we would contend that all products, especially ones as critical as application infrastructure, should be designed and implemented from an architectural blueprint. So, at a first pass, we say "both." But the underlying point here is that some large vendors (IBM for one) that have integration and application infrastructure solutions (but not distinct enterprise service bus solutions) are saying that the ESB is an architecture, or design pattern, from which an end user can assemble an ESB, using his current application infrastructure and integration products. While this is true an end user can roll his own, the question then becomes, "Does that make sense?" Only the individual organization can answer that, considering its current investments, initiatives, skills, and risk tolerances. For the majority of organizations, the answer will be "no," especially if production-quality ESB solutions are readily available.
So, as a general statement, we say that an ESB is a product, which evolves from an architecture.>> You can read her Q&A at: http://www.ebizq.net/hot_topics/esb/features/6132.html Gervas Yahoo!
