Amazon EC2 Future-dated Capacity Reservations lets you secure capacity up to 120 days in advance by specifying the capacity you need, the start date, and a commitment duration. Should plans change, you can now cancel your future-dated reservation. Depending on when you cancel, a charge may apply.

When a cancellation charge applies, EC2 presents a quote with the exact terms for you to review and accept before the cancellation takes effect. You can track any cancellation charges in the AWS Cost and Usage Report (CUR) 2.0 under a new value in the Capacity Reservation Status column.

This feature is available to all Future-dated Capacity Reservation customers. Refer to the AWS Capabilities by Region website for the feature's regional availability. For more details, refer to the Capacity Reservation user guide.
