Spot instances on 3Engines Cloud🔗

Spot instance is resource similar to Amazon EC2 Spot Instances or Google Spot VMs. In short, user is provided with unused computational resources for a discounted price but those resources can be terminated on a short time notice whenever on-demand usage increases. The main use case are ephemeral workflows which can deal with being terminated unexpectedly and/or orchestration platforms which can deal with forced scaling down of available resources e.g. Kubernetes clusters.
