How do Google Spot VMs compare to EC2 Spot Instances?

Google's Preemptible VMs have a guaranteed 24-hour maximum lifetime and 30-second shutdown notice. EC2 Spot can run indefinitely until AWS reclaims capacity with a 2-minute warning. Google's Spot VMs (newer) have no time limit but can be interrupted anytime like Spot. Both offer 60–91% discounts. Google has historically had more consistent Spot availability.

Which workloads are best suited for Spot Instance alternatives?

Batch data processing, ML model training, genomics pipelines, video rendering, CI/CD build agents, and stateless microservices are ideal. Avoid Spot for real-time databases, single-instance production services, and stateful applications without robust checkpointing or graceful interruption handling.

Can I use Spot Instances in Kubernetes clusters on alternatives to AWS?

Yes. GKE's Autopilot and Standard modes support Spot VMs. AKS has built-in Spot node pool support. Cast AI and Karpenter (multi-cloud) automate Spot selection and fallback for Kubernetes. Spot by NetApp extends this management across all major hyperscalers from a single control plane.
