What are spot VMs typically designed for?

Spot VMs are designed for cost-effective workloads that can tolerate interruptions. These virtual machines are often offered by cloud providers at significantly reduced prices, making them attractive for users who are looking to optimize their cloud spending. Spot VMs leverage excess capacity within a cloud provider's infrastructure, which means that they are subject to availability and can be terminated by the provider when demand for resources increases.

This pricing model makes spot VMs ideal for workloads that do not require guaranteed uptime. Such workloads might include batch processing jobs, development and testing environments, and other tasks that can be paused and resumed without severe impact. The ability to interrupt these VMs without penalty allows users to take advantage of lower prices while effectively managing their operational costs. Hence, workloads that are resilient to interruptions can benefit the most from the use of spot VMs.
