Cloud Computing and my company's data

I am looking into Cloud Computing for my company. The one question that I can't seem to get out of my head is; What happens to my data and the ability to use it if the Cloud computing company goes out of business?

Obviously, you should pick a provider that you think is solid and unlikely to go out of business however the real answer is that you should have a replacement provider lined up and a plan for how you're going to switch if the main provider goes bust. The key parts of such a plan are:

• Make sure you own and control the domain names, and use a completely independent provider to run your DNS
• Set up a completely automated backup system which moves all data off your primary provider.
• Have the backup provider ready-to-run at all times with just a DNS switch
• Test your switchover process periodically

An outsourced server farm is really no different to any other outsourced function. You just need to make sure you're not locked into a single supplier.
