What are AWS Spot Instances? Spot instances let you use spare AWS EC2 capacity at up to 90% discount compared to On-Demand pricing. However, AWS can reclaim these instances with short notice when capacity is needed, making pricing and stability crucial factors in your decision.

Compare Spot Prices Across Regions: AWS spot instance prices vary significantly by region, availability zone, and instance type. Use this comparison tool to find the cheapest AWS regions for your workload and maximize cloud cost savings.

Understanding Interruption Rates: Historical interruption frequency shows how often AWS terminates spot instances in each location. Lower interruption rates mean better reliability and fewer disruptions to your applications.

Interruption Rate Guide:
🟢 <5%: Excellent reliability - minimal interruptions
🟡 5-15%: Moderate stability - occasional reclaims
🔴 >15%: Higher volatility - frequent interruptions

Spot Instance Best Practices: Balance cost optimization with workload requirements. The lowest-priced regions may have higher interruption rates. For production workloads, consider diversifying across multiple instance types and availability zones to improve resilience while maintaining cost savings.
