This is interesting, from what I've read AWS no longer recommends setting spot instance prices so that they manage it themselves.
I wonder, if there's an actual advantage of avoiding spot interruptions by setting the spot price even higher than onDemand.
yeah true. it's an interesting question that involves not only startup/shutdown of instance/os overheads (i suppose they've probably thought about this) but also overhead for checkpoint/restart of your application.
i also suppose this way of thinking about it comes from thinking around how to minimize cost from a purely mathematical standpoint. when you think about how and why the spot market is operated, and what those short term spikes may actually be, it may run counter to the intended purpose. (cheap capacity that they may recall at any time, because capacity is actually fixed)
funny how market based approaches can gamify things sufficiently that sometimes they obscure the underlying intention or purpose of having a market in the first place.
