## Source File
|
||
- [[raw/Cloud & DevOps/Public-Cloud-Learning-Sessions/05_FinOps/public-cloud-learning-sessions-reducing-cloud-costs-20250318-170100-meeting-reco.md]]
|
||
|
||
## Summary
|
||
- 核心主题：云成本优化（FinOps）
|
||
- 问题域：公有云成本控制与优化
|
||
- 方法/机制：工作负载优化（现代化+Right Sizing）、费率优化（承诺使用折扣）
|
||
- 结论/价值：通过现代化升级、Right Sizing 和承诺折扣可显著降低云支出
|
||
|
||
## Key Claims
|
||
- 新一代实例通常比旧代更便宜，性能更优（M6 之后定价模型有变化）
|
||
- 从 Intel 迁移到 AMD 可节省 6-10% 按需价格
|
||
- Graviton 实例可为 Linux 工作负载节省 20-25% 成本
|
||
- GP2 升级到 GP3 可直接节省 20% 成本，无需停机
|
||
- EKS 集群升级到最新版本可避免高额的扩展支持费用
|
||
- Spot 实例可提供高达 90% 的折扣
|
||
- Right Sizing 可通过配置实例调度节省 40% 成本
|
||
- 承诺计划最低交易价值为每年 5,000 美元

## Key Quotes
|
||
> "Whenever there's a new family launched by the hyperscale, the latest families are almost cheaper." — Vinay, FINOPS team
|
||
|
||
> "Rather than spending up unnecessary moment on the extended support, you can deploy additional four or five cluster, right." — 关于 EKS 升级成本
|
||
|
||
## Key Concepts
|
||
- [[Workload Optimization]]：通过现代化和 Right Sizing 优化工作负载资源配置
|
||
- [[Rate Optimization]]：基于承诺使用获取费率折扣
|
||
- [[Right Sizing]]：识别正确的资源规格以匹配工作负载需求
|
||
- [[Savings Plans]]：AWS 承诺使用折扣计划
|
||
- [[Reserved Instances]]：预留实例，承诺使用折扣
|
||
- [[Spot Instances]]：竞价实例，最高可达 90% 折扣
|
||
- [[Graviton]]：AWS ARM 架构实例，节省 20-25% 成本
|
||
|
||
## Key Entities
|
||
- [[AWS]]：云服务提供商
|
||
- [[FINOPS Team]]：云财务管理团队
|
||
- [[EKS]]：Amazon Elastic Kubernetes Service
|
||
- [[EC2]]：Amazon Elastic Compute Cloud

## Contradictions
|
||
- 认知误区：认为新一代实例更贵 — 实际上新代实例通常更便宜且性能更好
|
||
- EKS 定价变化：M6 之后 M7/M8 定价略高，需要根据实际情况评估 |
