MaxPrice

The maximum hourly price you're willing to pay for the Spot Instances. We do not recommend using this parameter because it can lead to increased interruptions. If you do not specify this parameter, you will pay the current Spot price.

SpotInstanceType

The Spot Instance request type.

If you are using Spot Instances with an Auto Scaling group, use one-time requests, as the Amazon EC2 Auto Scaling service handles requesting new Spot Instances whenever the group is below its desired capacity.

Allowed values: one-time | persistent

Update requires: No interruption

ValidUntil

The end date of the request, in UTC format (YYYY-MM-DDTHH:MM:SSZ). Supported only for persistent requests.

  • For a persistent request, the request remains active until the ValidUntil date and time is reached. Otherwise, the request remains active until you cancel it.

  • For a one-time request, ValidUntil is not supported. The request remains active until all instances launch or you cancel the request.

Default: 7 days from the current date
