Amazon Elastic Compute Cloud
API Reference (API Version 2016-11-15)


Cancels one or more Spot instance requests. Spot instances are instances that Amazon EC2 starts on your behalf when the bid price that you specify exceeds the current Spot price. Amazon EC2 periodically sets the Spot price based on available Spot instance capacity and current Spot instance requests. For more information, see Spot Instance Requests in the Amazon Elastic Compute Cloud User Guide.


Canceling a Spot instance request does not terminate running Spot instances associated with the request.
