I am very pleased to announce that I have just updated my Grid, Distributed and Cloud Computing Resources Primer. This primer is 31 pages and a .pdf document (254KB) and freely available from the above URL. The primer gives an excellent overview of Cloud Computing along with a comprehensive listing of cloud, grid and distributed computing resources! It will be permanently archived in my White Papers site. [Updated July 12, 2012]
