Spot Instance

Definition

Spot instances (AWS) or preemptible VMs (GCP) provide cloud compute at steep discounts (60-90% off on-demand prices) in exchange for the possibility of interruption when the provider needs capacity back. They are suitable for fault-tolerant, stateless workloads like batch processing, CI jobs, and ML training.

Spot interruption handling (checkpointing, graceful shutdown) is essential for reliable spot-based workloads.
