EC2 Spot Description
Amazon EC2 Spot instances allow you to take advantage of unused EC2 capacity within the AWS cloud. Spot Instances can be purchased at up to 90% off the On-Demand price. Spot Instances can be used for many stateless, fault-tolerant or flexible applications, such as big data and containerized workloads. Spot Instances can be used to launch and maintain applications that are running on AWS services like CloudFormation (EMR, ECS), CloudFormation, Data Pipeline, Data Pipeline, CloudFormation and AWS Batch. To further optimize workload cost and performance, Spot Instances can be combined with On-Demand, Savings Plans Instances, RIs, and RIs. Spot Instances are able to offer the scale and cost savings necessary to run hyper-scale workloads due to AWS's operating scale.
