ESB vs. SOA

It seems that "ESB vs. SOA" is becoming the new religious war, just like "windows vs. unix", "J2EE vs. .NET', and more obscure ones likes "COM vs. CORBA".

Seems like everyone is weighing in.  David Linthicum gives a good summary of some of the recent activity in this blog entry of his.

Always interested in a good argument, I published an article with a different spin on this recently in ComputerWorld.

Comparing ESB and SOA seems more like comparing a road and a car. An ESB is more like the medium upon which an SOA can be implemented. (It's not the only medium, of course.) I understand the horizontal versus vertical slices you describe on the Computerworld article, however, I still feel that an ESB is a thing you can buy whereas an SOA is more of an architectural methodology - not something that sits on a shelf.

The Message Oriented Architecture could be more analagous to an SOA. Both could be implemented utilizing an ESB, however, differently. Care to compare and contrast MOA versus SOA?

Yes, ESB paves the road and SOA guides the traffic. There's not like 'windows vs. unix' case.
But it's good approach to present the horizontal versus vertical slice view to the business to buy SOA idea. That is the value from the article.
