What is the reason anyone would pay more for a spot instance than an on-demand instance?

- great_psy 3y agoMaybe poorly architected software, where it’s cheaper to increase the value of a variable than have a bunch of API calls that check the current onDemand price and call different APIs depending on which number is smaller.
- sokoloff 3y agoIf an instance on-demand is, for the sake of easy discussion, $1.00/hr and the spot rate is usually $0.30/hr, it might make sense to bid $1.25/hr (or $1.26/hr) if you didn’t want to get pre-empted. Most hours, you’d pay something close to $0.30/hr. Some hours, you’d pay over a $1.00/hr, but you’d save money overall against on-demand. (This ignores Reserved Instances and Savings Plans.)
