When should you use Spot Instances instead of On-Demand Instances to reduce EC2 costs?
answer
Spot Instances should be used for fault-tolerant, flexible, or stateless workloads such as batch processing, big data analysis, or CI/CD pipelines, where interruptions can be handled gracefully. They can save up to 90% compared to On-Demand pricing.
