ProgrammableWeb pointed out an InformationWeek story that claimed 28% of Amazon’s sales in early 2005 were attributable to Amazon affiliates. And C|net claims Amazon now has 180,000 AWS developers (up from the 140,000 Amazon was claiming about a year ago).
(Note: not every Amazon affiliate/associate is an Amazon Web Services (AWS) developer, but Amazon hasn’t shared more specific numbers.)
These slides, from Amazon’s AWS developer relations team explain a lot about what AWS is.
