Amazon EC2's Future-dated Capacity Reservations enable users to reserve cloud computing capacity up to 120 days ahead by specifying required capacity, start date, and duration. The recent update allows customers to postpone the start date if their plans change before the reservation begins, providing greater scheduling flexibility.
When a start date is postponed, EC2 offers a revised quote reflecting the new start date and any changes to the commitment duration. After customer approval, the reservation updates accordingly. This feature is available to all users of Future-dated Capacity Reservations with regional availability details provided by AWS. It aims to accommodate dynamic capacity planning needs in cloud environments.
