I found this diag on IBM site

Halfway down is the diag that positions network perf etc: in relation to benefits of GRID
This introduction to GRID compares GRID with Clustering, CORBA & Peer-2-Peer. It handles the comparison quite well as the writer knows what he is talking about & seems to hit all the key points. Re Corba for example, he highlights the incompatibility of Corba with the web (exploitation of http & the lack of use of web end-point identiites). Web Services builds on the best of Corba by solving the shorcommings just mentioned thus taking full advantage of the web and *best-of-all* introduces the concept of dynamic late binding between interfaces. Something that Corba can't do.
