To terminate any outstanding instances, we use the instanceIds array, which we populated with the
instance IDs of those instances that transitioned to the active state. We terminate these instances by
assigning this array to the InstanceId member of a TerminateInstancesRequest object, then
passing that object to the ec2.TerminateInstances API.

TerminateInstancesRequest terminateRequest = new TerminateInstances

terminateRequest.InstanceId = instanceIds;
