Amazon introduced On-Demand Capacity Reservations for Aurora and RDS to enable customers to reserve compute capacity in specific Availability Zones without long-term commitments. This reservation ensures that database instance operations—such as create, restore, or scale—succeed without capacity-related failures during critical business events.
Customers can select instance classes, engines, and Availability Zones to reserve capacity that supports multi-AZ deployments, cancel anytime, and benefit from automatic application of existing discounts. This feature is globally available across commercial AWS Regions, targeting workloads that require predictable database resource availability.
