I look in on this stuff from the enterprise side of things with interest. I want to get out of the business of hosting an internal datacenter entirely as soon as possible (that decades old, and apparently intractable AS400 accounting system notwithstanding), and would prefer to move things cloudward. Right now though, it seems that we are either limited to niche players or proprietary solutions(AWS, etc.), and the risk of being held hostage by an underperforming vendor remains high. We are experimenting with certain applications (CRM, for example) being hosted in the cloud. Until there is a standard cloud-hosting platform, with multiple large players offering services that would allow us to very simply move from one service to another without redisigning major parts of applications there won't be much movement to the cloud in our space. (part of this is a legacy of horrendous application design in the enterprise space, part of it is just the natural legacy of having much older legacy applications than web companies do, and part of it is a reflection of large organizations being terribly risk averse.)
