I just read the entire blog (only about 7 pages of stuff) over at http://www.3tera.com/hotcluster.html. Some pretty cool stuff there if you are interested in learning more about utility computing and real world applications. I am more interested in it from an academic, wow-that-is-incredibly-cool point of view and am not so much interested in the economics behind it, but it's definitely worth checking out. The blog is the first I have found that I would recommend but I am sure there are some more out there... Two picks from the blog... What is utility computing? Is there a difference between Grid and Utility Computing?
