How do spot VM instances factor into cost planning under a CSP Azure Plan?

Azure Spot Virtual Machines (which offer significant discounts in exchange for Microsoft being able to evict the VM when capacity is needed elsewhere) work the same way under a CSP Azure Plan as under any other Azure subscription — they're a platform feature, not something tied to billing model.

Spot VMs are best suited for interruptible, fault-tolerant workloads (like batch processing or stateless compute) rather than anything requiring guaranteed uptime. If this fits part of your workload, it can meaningfully reduce costs for that portion of your infrastructure.
