Comments on: The benefits of an ESB http://www.soabloke.com/2008/01/31/the-benfits-of-an-esb/ pushing soa up the slope (with a pointy stick) Tue, 30 Nov 2010 19:23:34 +0000 hourly 1 http://wordpress.org/?v=3.2.1 By: Saul http://www.soabloke.com/2008/01/31/the-benfits-of-an-esb/comment-page-1/#comment-640 Saul Wed, 21 Apr 2010 01:51:18 +0000 http://www.soabloke.com/2008/01/31/the-benfits-of-an-esb/#comment-640 @Jeff, thanks for your comment. I agree that change is always difficult but a code change can have different degrees of impact depending on the architecture of your system. My point is that a Service Bus architecture helps promote architectural practices such as loose-coupling which minimise the cost of change. I also agree that architects should carefully consider the benefits and costs of adopting an ESB architecture. There is complexity which needs to be offset by benefits. But benefits can be realised in the right circumstances - one man's bloat is another man's infrastructure. There are other point-mechanisms for addressing each of the benefits I describe. My experience is that these other mechanisms eventually add up to just another middleware layer in the end. I'd be happy for you to expand on your experience if it is different! @Jeff, thanks for your comment.

What's the difference, a code change is a code change, we're just doing it in a different place now. I can go on and on, but the other "benefits" can also be strategically implemented without the use of an ESB. The ESB simply introduces another middleware component that can be difficult to diagnose during failure and/or introduce issues during deployment. It is a good example of code bloat and should be seriously reconsidered prior to implementing in your enterprise.
