Azure Spot Virtual Machines

Azure Spot Virtual Machines are a compute service designed to increase capacity for running interruptible workloads at a lower cost. You can utilize Azure Spot VM instances and VM scale sets specifically for fault-tolerant workloads that can handle interruptions. This approach allows you to leverage unused Azure capacity efficiently without committing to dedicated resources.

Choose this service when you need to run non-critical, fault-tolerant tasks that can tolerate being preempted. The pricing model is pay-as-you-go, which suits flexible budgeting. Be aware that there is no free tier available, so you will incur costs based on usage. This limitation means even small-scale testing or development efforts will generate charges.
