Updated. Amazon Web Services (AWS), as the trailblazing provider of Infrastructure as a Service (IaaS), has changed the dialog about computing infrastructure. Today, instead of simply assuming that you’ll be buying and operating your own servers, storage and networking, AWS is always an option to consider, and for many new businesses, it’s simply the default choice.
I’m a huge fan of cloud computing in general and AWS in particular. But I’ve long had an instinct that the economics of the choice between self-hosted and cloud provider had more texture to it than the patently attractive sounding “10 cents an hour,” particularly as a function of demand distribution. As a case in point, Zynga has made it known that for economic reasons, they now use their own infrastructure for baseline loads and use Amazon for peaks and variable loads surrounding new game introductions.
