How big is Amazon's cloud? It's huge, and getting huger. Amazon Web Services said this week that its S3 cloud storage service housed 262 billion objects at year-end of 2010, more than doubling in size from 102 billion objects at the close of 2009. The peak request rate for S3 is now in excess of 200,000 requests per second, according to Amazon's Jeff Barr.

While these data points provide snapshots of activity on particular AWS services, there's little doubt that Amazon's cloud computing operation is seeing incredible growth.
