What's the difference between "the cloud" and a data centre providing hosting? A lot of companies that I've worked with over the years have been quite happy to move their data/processing operations out to a 3rd party data centre, but seem to resist moving operations to "the cloud". As far as I can determine, "the cloud" is just a large data centre (or centres) run by amazon/MS/Google.

That being said, the latest MS offering for SQL Azure seems like quite a nice "fit" for those businesses (or lines of business) that need to upgrade their MS Access databases to something more substantial.
