AI打分理由: "正文主线是通用型EC2 C8id、M8id实例扩展至悉尼、孟买和加拿大中部区域，并非超节点、AI Rack或机架级AI基础设施。来源为AWS官方，新增事实包括区域可用性、最高22.8TB本地NVMe存储、相对第六代的性能提升、带宽权重调节及EFA支持规格；固定知识库未显示该区域扩展事实已完整出现，但未命中不能证明首次发布。虽然具有明确商用上线动作和完整参数，应用重点仍是媒体处理、数据库及实时分析等通用云工作负载，没有新的AI机架拓扑、关键部件路线或机架级部署机制，命中弱相关强否决，当前页面不值得纳入超节点业务情报库。"

Amazon Elastic Compute Cloud (Amazon EC2) C8id and M8id instances with up to 22.8 TB of local NVMe-based SSD block-level storage are now available in additional regions. C8id instances are now available in Asia Pacific (Sydney) and Canada (Central) and M8id instances are available in Asia Pacific (Mumbai) and Canada (Central).

Amazon EC2 C8id and M8id instances offer 3 times more vCPUs, memory and local storage compared to previous sixth-generation instances. These instances deliver up to 43% higher compute performance and 3.3 times more memory bandwidth compared to previous sixth-generation C6id and M6id instances. They also deliver up to 46% higher performance for I/O intensive database workloads, and up to 30% faster query results for I/O intensive real-time data analytics compared to previous sixth generation instances.

- **C8id instances** are ideal for compute-intensive workloads, including those that need access to high-speed, low-latency local storage like video encoding, image manipulation, and other forms of media processing.
- **M8id instances** are best for workloads that require a balance of compute and memory resources along with high-speed, low-latency local block storage, including data logging, media processing, and medium-sized data stores.

Additionally, customers can now adjust the network and Amazon EBS bandwidth on these instances by 25% using EC2 instance bandwidth weighting configuration, providing greater flexibility with the allocation of bandwidth resources to better optimize workloads. These instances offer Elastic Fabric Adapter (EFA) networking on 24xlarge, 48xlarge, metal-24xl, and metal-48xl sizes.

Customers can purchase these instances via Savings Plans, On-Demand instances, and Spot instances. For more information visit the [Amazon EC2 C8id](https://aws.amazon.com/ec2/instance-types/c8i/) and [Amazon EC2 M8id](https://aws.amazon.com/ec2/instance-types/m8i/) pages.
