I'd like to also see your planning for cloud failure. This would be very interesting for me. I have read about cases where a cloud provider goes out of business and end-users are given only a few days to pull everything off. Also an exploration of the legal aspects would be interesting. Right now my understanding of the law says that if the Feds grabbed the servers for an unrelated issue they wouldn't have to give SSC back their data. How will you prepare for that (and should you?). All very interesting. Another question might be now that you don't control your servers and data 100% will you do anything different. An admin at a cloud provider was recently fired and used some back doors he set up to cause trouble. Will you prepare for that? Will you save money? What's your ROI? Will you prep an ROI analysis before moving?

I think you should do it (all of it).
