What is Spot Instance?

Discounted cloud compute instances that use spare capacity at significantly lower prices but can be interrupted with short notice.

Spot instances (AWS) or preemptible VMs (GCP) offer 60-90% discounts by using unused cloud capacity. The trade-off is that the provider can reclaim instances with 2-minute notice when demand increases.

Ideal for fault-tolerant, stateless workloads: batch processing, CI/CD builds, data analysis, rendering, and distributed computing. Not suitable for databases or long-running stateful applications. Spot fleets and interruption handling strategies maximize savings safely.
