When to Use Spot Instances

You can use Spot Instances for various fault-tolerant and flexible applications. Examples include stateless web servers, API endpoints, big data and analytics applications, containerized workloads, CI/CD high performance and high throughput computing (HPC/HTC), rendering workloads, and other flexible workloads.

Spot Instances are not suitable for workloads that are inflexible, stateful, fault-intolerant, or tightly coupled between instance nodes. Spot Instances are also not recommended for workloads that are intolerant of occasional periods when the target capacity is not completely available. We strongly warn against using Spot Instances for these workloads or for attempting to fail-over to On-Demand Instances to handle interruptions.
