AI打分理由: "正文主线是AWS EC2容量预留资源组新增对Capacity Blocks for ML和可中断容量预留的支持，属于云资源预留与实例启动管理，并非超节点、AI Rack或机架级基础设施。来源为AWS官方发布，新增事实包括支持混合预留类型、Fleet/Auto Scaling优先级及按需容量回退，并已在多数支持区域上线。固定知识库未发现同一功能记录，但Top 5不完整，不能据此认定绝对首次发布。文章缺少机架拓扑、互连、功耗、散热或规模部署数据，未命中高价值准入通道，因主题弱相关判为非优质。"

Starting today, you can add Amazon EC2 Capacity Blocks for ML and interruptible Capacity Reservations to Capacity Reservation Resource Groups. Amazon EC2 offers different reservation offerings such as On-Demand Capacity Reservations (ODCRs), interruptible Capacity Reservations, and Capacity Blocks for ML. Previously, a Capacity Reservation Resource Group could only include 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.

To use this feature, create a Capacity Reservation Resource Group, add any Capacity Reservation to it, and then target the group in your launch request. When using EC2 Fleet and EC2 Auto Scaling groups, you can also specify your prioritization preferences across reservation types, and 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. This feature is available in all AWS Regions where Capacity Blocks for ML and interruptible ODCRs are supported, excluding AWS GovCloud (US) and China Regions. To get started, see [Capacity Reservation Resource Groups](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/cr-groups.html) and the [Capacity Reservations user guide](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-capacity-reservations.html).
