I'm trying to come up with some data on how much computing power the current cloud platforms represent. (Microsoft Azure, Amazon Elastic Compute Cloud, Google App Engine. Others?)
Stuff like how many physical/virtual machines, storage space. How many datacentres are the big players setting up/running already. Any metrics would be fine.
(Also, if you know of any pictures of the server-containers or related, please link to them.)
Quantifying and visualizing it will help me better explain what the cloud is all about.
