Spot Instances
How 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 VMsPreemtible InstancesHow 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 tolerant * You are very cost sensitive * Your workload is NOT immediate * Example: Non immediate batch processing jobs RESTRICTIONS: * NOT always available * NO SLA and
- Key Difference: Does not have a maximum runtime
