Azure Spot Virtual Machines (Spot VMs) are a cost-saving compute option in Microsoft Azure that allows users to access unused Azure compute capacity at significantly discounted prices compared to regular VMs. However, these instances are not guaranteed to run continuously and can be evicted by Azure when capacity is needed elsewhere, making them ideal for workloads that are flexible, interruptible, or fault-tolerant such as batch processing, testing, rendering, and big data jobs. This model helps organizations optimize cloud costs while still leveraging scalable infrastructure. In your opinion, what are the best use cases for Azure Spot VMs, and how can organizations design applications to handle interruptions effectively while maximizing cost savings?
