Spot Instances

Leverage spare EC2 capacity for up to 90% savings on compute, optimizing costs for flexible, fault-tolerant workloads.

Spot Instances deliver massive cost savings (up to 90% off On-Demand pricing) by utilizing Amazon EC2's unused compute capacity. This is a powerful tool for flexible, stateless, or fault-tolerant applications: think Big Data, containerized workloads, or CI/CD pipelines. The core operational factor is the interruption risk: AWS will reclaim the instance with a two-minute notice if the capacity is required. To maximize uptime and savings, diversify your requests across multiple instance types and Availability Zones, using tools like Spot Fleet for automated capacity management.
