## Summary
|
||
Right Sizing（正确调整规格）是识别正确的资源规格以匹配工作负载性能和容量需求的过程。
|
||
|
||
## Definition
|
||
通过分析实际 CPU、内存、网络使用数据，推荐合适的实例规格，避免资源浪费。
|
||
|
||
## Key Techniques
|
||
- **EC2 Right Sizing Recommendation**：捕获 CPU、内存、网络数据提供推荐
|
||
- **实例调度**：为非生产环境配置按业务时间开关机，可节省 60% 成本
|
||
- **闲置资源清理**：识别和删除空闲负载均衡器、未关联弹性 IP、低利用率 EBS 卷
