Preemptible VM Instances ● What Preemptible VMs are ○ Up to 80% cheaper than regular VMs. (~$0.01 per core hour) ○ Very easy to use -- just flip one switch in the UI, API or command line ○ Many of our biggest customers run huge clusters (10k+ cores) with great success and savings. ● Things to keep in mind ○ Same great disk, OS images and network ○ Google Compute Engine can preempt (i.e. shutdown/take-away) the VM with 30 seconds of notice ○ Maximum 24 hours of uptime ○ No SLAs or guarantees of any kind but we historically see preemption rates of 5-15%
