Description

Creates a Spot Instance request. For more information, see Spot Instance requests in the Amazon EC2 User Guide for Linux Instances. We strongly discourage using the RequestSpotInstances API because it is a legacy API with no planned investment. For options for requesting Spot Instances, see Which is the best Spot request method to use? in the Amazon EC2 User Guide for Linux Instances. We are retiring EC2-Classic. We recommend that you migrate from EC2-Classic to a VPC. For more information, see Migrate from EC2-Classic to a VPC in the Amazon EC2 User Guide for Linux Instances.

Parameters

-AvailabilityZoneGroup <String>
The user-specified name for a logical grouping of requests.When you specify an Availability Zone group in a Spot Instance request, all Spot Instances in the request are launched in the same Availability Zone. Instance proximity is maintained with this parameter, but the choice of Availability Zone is not. The group applies only to requests for Spot Instances of the same instance type. Any additional Spot Instance requests that are specified with the same Availability Zone group name are launched in that same Availability Zone, as long as at least one instance from the group is still active.If there is no active instance running in the Availability Zone group that you specify for a new Spot Instance request (all instances are terminated, the request is expired, or the maximum price you specified falls below current Spot price), then Amazon EC2 launches the instance in any Availability Zone where the constraint can be met. Consequently, the subsequent set of Spot Instances could be placed in a different zone from the original request, even if you specified the same Availability Zone group.Default: Instances are launched in any available Availability Zone.

Outputs

Amazon.EC2.Model.SpotInstanceRequest or Amazon.EC2.Model.RequestSpotInstancesResponse
This cmdlet returns a collection of Amazon.EC2.Model.SpotInstanceRequest objects. The service call response (type Amazon.EC2.Model.RequestSpotInstancesResponse) can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.
