At least with AWS you have availability zones. Personally, anything I code against these APIs, I make as encapsulated/swappable as possible. Downtime aside, I am worried about being cancelled or if someone goes out of business or if someone starts offering a piece of the puzzle that will save me a signficant amount of money. Got to be able to adapt as fast as possible. Fortunately, Linux lock-in is not something that keeps me up at night :-). This is the beauty of IaaS (VMs) vs PaaS (framework X).
