Capacity Reservation Resource Groups now support Amazon EC2 Capacity Blocks and interruptible Capacity Reservations in AWS GovCloud (US) Regions

AWS GovCloud (US) Regions

Starting today, you can add Amazon EC2 Capacity Blocks for ML and interruptible Capacity Reservations to Capacity Reservation Resource Groups in AWS GovCloud (US) Regions. Previously, a Capacity Reservation Resource Group could only include On-Demand Capacity Reservations (ODCRs). Now you can add any type of Capacity Reservation to a Capacity Reservation Resource Group, making it easier to launch EC2 instances across your entire portfolio of reserved capacity.

What to do

• Create a Capacity Reservation Resource Group.
• Add any Capacity Reservation to it.
• Target the group in your launch request.
• Specify prioritization preferences across reservation types when using EC2 Fleet and EC2 Auto Scaling groups.
• Configure automatic fall back to EC2 On-Demand capacity when there is no capacity remaining across your reservations.

There are no additional charges for using this feature. With the addition of AWS GovCloud (US) Regions, this feature is now available in all AWS Regions where Capacity Blocks for ML and interruptible ODCRs are supported, excluding China Regions.
