I would add that a huge selling point is the on-demand aspect. You can get VMs/containers/functions running in a few seconds. This is great for experiments, bursting, etc but if you are using compute capacity for a year, it should be understood that you should rent a box instead. Like, you wouldn't rent a dozen ZipCars every day. If your business required a fleet of cars, you would quickly look for a better arrangement than pay-by-the-minute "convenient" app services.
