We use Kubernetes and spot instances to reduce EC2 billing up to 80%

This is the second response of this sort that I'm replying to.

"A lot more stable" isn't really a desirable characteristic of ephemeral compute capacity. In my experience, the less frequently the instances went away, the more complacent the operators became.

Preemptible instance are stable in the sense that you know they're going away within 24 hours and must be prepared for that.

true that.

spot used to be that way and the price was very sensitive. but AWS tweaked it so that it's more stable.

to the point, after a year or 2 of running spot instances, we don't feel the difference of spot and ondemand that much. we got complacent.
