AWS EC2 Capacity Reservations Enhanced: Split, Move, Modify Features

Originally published at ssojet AWS has introduced updates to Amazon EC2 On-Demand Capacity Reservations (ODCRs), adding split, move, and modify functionalities. These features enhance resource management and optimize costs for users. Split Feature The split feature enables users to divide existing ODCRs into smaller, more targeted reservations. This is particularly useful when demand fluctuates. Users can create new reservations from the unused capacity of larger, underutilized reservations. Image courtesy of AWS News blog The split operation helps manage capacity across teams more efficiently, allowing for redistribution of resources without the overhead of new reservations. Move Capability The move capability allows users to transfer unused capacity slots between existing ODCRs. This prevents wasted capacity and minimizes costs by reallocating resources to where they are needed most. It offers flexibility in managing resources without disrupting running workloads. Image courtesy of AWS News blog This ability to move capacity enhances overall efficiency and resource utilization. Modify Feature The modify feature allows users to adjust reservation attributes without creating new reservations or disrupting workloads. Users can change instance quantity, switch between reservation types, or modify the reservation's end date.
