Post a Comment On: Network of Things

The article by Dave Chappel provides a good description of what ESB is and its roadmap. However there is one critical architectural flaw in ESB. In trying to scale ESB, one has to scale the container. This is very difficult task as we all know from trying to scale other industry standard containers such as J2EE.

IMHO, application networks are better choice for scalable services that ESB offers. The reason is that in a network it is not the control but the data path that is scaled. From networking, we know scaling a data path is far easier than scaling a control. A highly scalable data path with distributed control across the service network can provide all the services of an ESB without the concomittant headaches for IT of having to integrate another layer of middleware on top of already difficult middleware landscape.
