Preemtible Instances


How Preemtible Instances works in GCP:

  • Short-lived cheaper (upto 80%) compute instances
    • Can be stopped by GCP any time (preempted) within 24 hours
    • Maximum time for running is 24 hours
    • Instances get 30 second warning (to save anything they want to save)
  • Use Preempt VM's if:
    • Your applications are fault tolerantfault tolerantCan stop and start at any time
    • You are very cost sensitive
    • Your workload is NOT immediate
    • Example: Non immediate batch processing jobs

RESTRICTIONS:

  • NOT always available
  • NO SLA and CANNOT be migrated to regular VMs
  • NO Automatic Restarts
  • Free Tier credits not applicable

Similar to AWS Spot InstancesSpot InstancesHow Spot Instances works in Azure: * Buy unused compute capacity for VMs at savings * Ideal for interruptible workloads No specific completion time** needed How Spot Instances works in GCP: Spot VMs**: Latest version of preemptible VMs Key Difference**: Does not have a maximum runtime * Compared to traditional preemptible VMs which have a maximum runtime of 24 hours * Other features similar to traditional preemptible VMs * May be reclaimed at any time with 30-second notice * NOT al
