CapacityReservationSpecification

Describes an instance's Capacity Reservation targeting option. You can specify only one parameter at a time. If you specify CapacityReservationPreference and CapacityReservationTarget, the request fails.

Use the CapacityReservationPreference parameter to configure the instance to run as an On-Demand Instance or to run in any open Capacity Reservation that has matching attributes (instance type, platform, Availability Zone). Use the CapacityReservationTarget parameter to explicitly target a specific Capacity Reservation or a Capacity Reservation group.
