Automated excerpt
Spot is safe when your job checkpoints to storage that outlives the machine, saves again when the notice arrives, resumes on start and can fall back when spot capacity runs out; without that, a few reclaims can make spot cost more than on-demand. Sources: AWS interruption notices, GCP Spot VMs, Azure Spot VMs, Modal preemption. Most spot guides stop at "use checkpoints".
