[ Cloud Computing ] Re: Cloud Computing ROI model

Geva,
 
There is an ACM paper on S3 analysis which includes costs - "Amazon S3 for Science Grids: a Viable Solution?"
Authored by Palankar, Iamnitchi, Ripeanu, and Garfinkel.

and Amazon has some case studies ... that may lead you to asking the actual companies used in the case some more detail
