RE: The Business of Building Clouds

Picking a provider that has data center failover is critical - but it does mean that you write your application in a way that can failover gracefully. Cloud providers need to provide the base infrastructure to do so OR constrain the user to a particular programming paradigm (like the limitations of google app engine)

I expect in the future that cloud computing systems will provide the concept of "cloud events" in case of major datacenter failures. I just don't see any way round it.

How do you move apps from the cloud that went down?.. ;-)
