Oops, I was linking to a specific post, I meant to link to the top of the thread. There gchiu links to his website where he says this: "... Amazon has also just recently created the abililty to run Windows 2003 virtual servers for the small cost.
The implication of this is that we should be able to provide a service whereby if your hardware suffers a failure, and you have been using the backup service, then we can rapidly provision a new server for you on Amazon containing all your most recent set of data. Thus you have the plus of offsite backup, and now the major benefit of having a redundant server available to you in the cloud."
Now it's a backup for him, but it's only a step away from being the primary host for some customer of his.
