## Summary
|
||
|
||
- **核心主题**：AWS 资源优化（Right Sizing）的全面指南
|
||
- **问题域**：云成本优化、资源效率提升
|
||
- **方法/机制**：通过识别正确规格的云资源匹配实际工作负载需求，实现成本节省

||
## Key Claims
|
||
|
||
- Right Sizing 是识别正确资源规格以匹配工作负载需求的过程
|
||
- EC2 Right Sizing 推荐报告是实施 Right Sizing 的主要工具
|
||
- 实例调度和闲置资源清理是 Right Sizing 的补充手段
|
||
- Right Sizing 与费率优化（Savings Plans、Reserved Instances）结合使用效果更佳
|
||
|
||
## Key Quotes
|
||
|
||
> "Right Sizing is the process of identifying the right size of resources to match your workload requirements."
