Wired has an interesting article this month on Cloud Computing / Amazon Web Services / Jeff Bazos (AKA Geek God.) The title is "Cloud Computing. Available at Amazon.com Today". It's a little too ass kissy for my taste. But It's generally pretty good. a good mainstream overview of the AWS and cloud computing in general.
I also found this tidbit interesting. "When AWS launched in earnest a couple of years ago, with the S3 storage utility, Amazon's computer system was at times running at just 10% of its capacity, according to CEO Jeff Bezos. Now, AWS demand has "far exceeded the excess capacity of our internal system," says AWS head Andy Jassy. AWS is "now big enough to be piling up its own silicon.""
