(not low end but..) Experiences with spot instances?
We are using Google Cloud at work and today I configured a node pool For one of our Kubernetes clusters with spot instances to test it for a few weeks and see how it goes. Does anyone know how often these spot instances are terminated? Also, has anyone every been in a situation where new instances were not available for a long period of time? Thanks

See https://cloud.google.com/kubernetes-engine/docs/how-to/preemptible-vms, they’re always terminated in 24 hours, though I’ve never seen a termination when I was working with AWS spot instances. GCP is a much smaller player, so there’s that.
Yes, absolutely! Many customers like to spawn thousands of instances of a certain type at once, and if they have a better bid than you, you’d not get any instances for a long time. The way around this is to just use a different instance type with similar performance characteristics.
Thanks, but I am referring to the new "spot" instances, not the preemptible ones. AFAIK there's a differencce
It is the same thing. The only difference is the 24 hours limit, they removed it in Spot instances (but your instances could still be killed at any time even after a few minutes).
Looks like largely a rebranding effort so it is the same name as in AWS so people are not confused.
