I did something like this in GKE with preemptible instances which are guaranteed to go away at least once every 24 hours. I had separate node groups for stateless and stateful work loads. My clusters were roughly a 50/50 mix of each. Worked out pretty well and yielded some decent cost savings.

preemptible instances are worse than spot. we observed there were spot instances that last a year for us.

  That presumes that an instance type that last longer is "better".

    Yes, preemptible instances are expected to be expendable, I don't see this as a bad thing.

      i believe what he meant is by being shutdown more frequent, we will be forced to build a more resilent system. otherwise, we would be more complacent.
