My point re aws is that aws is way more expensive than data center space and hardware; if you have someone competent and inexpensive in the midwest to handle the datacenter/hardware stuff, it makes sense to move off of aws much sooner than in the bay area, where people to manage the hardware side of things are going to cost you a whole lot. Therefore, your amazon bill is, in a way, location dependent.
