Today, we are introducing multiple enhancements to Amazon EC2 On-Demand Capacity Reservations in Cluster Placement Groups (CPG-ODCRs). CPG-ODCRs provide customers with assured capacity and offer low latency and high throughput between instances within the same Cluster Placement Group (CPG). Now, customers using CPG-ODCRs can benefit from two additional capabilities that make them easier to use. First, customers can now add ODCRs belonging to different CPGs to Resource Groups which will enable customers to manage and target groups of reservations spread across multiple Placement Groups. Second, customers can share CPG-ODCRs across multiple AWS accounts through AWS Resource Access Manager, which allow them to create central pools of capacity and use them efficiently across workloads in different accounts.
Customers can get started with these capabilities of CPG-ODCR by using the AWS CLI/APIs or by visiting the AWS Management console. These capabilities are now available in all AWS regions except China, and they are available at no additional cost. To learn more about these capabilities, please refer to the Capacity Reservations user guide.
