I heard the figure of $100M in AWS (Amazon Web Services) revenues bandied about lately.  Not too shabby for a business that started out as a spare-time as-is reuse of Amazon’s infrastructure.  By far the healthiest supplier of IaaS (Infrastructure as a Service)

Compare them to Google and Microsoft, who started PaaS (Platform-as-a-service) businesses instead of IaaS.  PaaS (if I understand it right) tries to get developers to develop applications for the platform, whereas IaaS “just” provides a run-time environment for applications built elsewhere.

Microsoft of advertising the bajeezus out of Azure, but I’m not hearing much about great results.  Certainly no $100M in revenues (yet?).  And Google seems to be flailing about with its various cloud and app-dev platforms.

Makes IaaS look like the right bet, at least so far.

Thoughts?
