Why would you 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.
