EC2 Capacity Reservation Resource Groups Now Support Capacity Blocks and Interruptible Reservations

AWS has enhanced EC2 Capacity Reservation Resource Groups (CRGs) to support Amazon EC2 Capacity Blocks for ML and interruptible Capacity Reservations. Previously limited to On-Demand Capacity Reservations, this expansion simplifies managing diverse reserved capacity portfolios for EC2 instances. Users can now easily launch instances across all reservation types, with options for prioritization and automatic fallback to On-Demand capacity when using EC2 Fleet or Auto Scaling. This new capability is available in most AWS Regions at no extra cost.
