Preemptible VMs + Kubernetes = Awesome.

If you manage to build you app/infrastructure in away that can survive nodes shutting down at random times (or if you don't care about restarts) then you can reduce your infra costs for 80%.

We have a staging cluster running on preemptive instances and as soon as one instance goes away we get a different one. Everything gets deployed automatically. Regular internal users checking out various webpages don't even notice.

We're looking into changing our 24/7 infra (which needs to be 24/7) to something that can be run mostly on preemptive (with a couple of normal instances for services that can't be randomly killed).

Super happy about our move to GCP and our K8S experience.
