the little cloud that could...

so with the recent failure in the MS/Sidekick cloud i got to thinking...what if?

what if we put our data in a cloud ($billions in data assets)?
what if all that data disappeared?
what would the user experience be like with the data in the cloud?
could we create our own cloud in our Primary Data Center?
should the cloud be "clustered" for application and data availability?

oh well that's what i had running through my head....

feel free to answer the q's above or add more!
