That's true.
but thinking that out... I guess if Amazon allowed everyone to programatically do that via an API warning then I guess everyone would simply build their software to bid up 1c at the time of warning... and at scale, everyone doing that would simply inflate the spot price higher and high to the point it would approach the full cost.
- kevinpet 17y agoThat's assuming people need to keep things running at all times, whatever the cost. This is for those people who want to do their calculations only when CPU is cheap.
- dotBen 17y agoNo because this could become a hack... using the mechanism I describe above I could keep instances going at below market rate. I can see some people gaming the system in this way if the system allows it
- bdonlan 17y agoThe instance always runs at market rate. You set a _maximum_ price but are charged less than that if the market rate is lower. So there's no sense in doing such a reactive system when amazon does it for you.
