- [[raw/Cloud & DevOps/Public-Cloud-Learning-Sessions/05_FinOps/public-cloud-learning-sessions-storage-cost-optimization-20240305-160037-meeting.md]]
|
||
|
||
## Summary
|
||
- 核心主题：AWS 存储服务成本优化最佳实践
|
||
- 问题域：云成本优化、存储分层、存储服务选型
|
||
- 方法/机制：存储类型选择、生命周期策略、数据分层、智能分层
|
||
- 结论/价值：通过合理选择存储类型和使用生命周期策略可显著降低存储成本
|
||
|
||
## Key Claims
|
||
- GP3 卷相比 GP2 成本降低 20%，且可独立扩展 IOPS 和吞吐量
|
||
- EBS 快照归档层相比标准层成本降低 75%，但恢复时间更长，需保留 90 天
|
||
- EFS 不频繁访问层最小计费对象大小为 128KB
|
||
- S3 智能分层可自动根据访问模式将数据在不同存储层之间移动
|
||
- ADM 迁移到 FSx for NetApp ONTAP 后成本降低 60%
|
||
|
||
## Key Quotes
|
||
> "With GP3, you can scale IOPS and throughput independently of the volume size." — AWS Storage 最佳实践
|
||
> "With intelligent tiering we can automatically move data from warmer to colder color storage tiers based on object access patterns." — S3 智能分层说明
|
||
|
||
## Key Concepts
|
||
- [[EBS-GP3]]：通用型 SSD 卷，推荐作为默认存储类型，成本比 GP2 低 20%
|
||
- [[EBS-Snapshot-Archive]]：EBS 快照归档层，成本比标准层低 75%
|
||
- [[EFS-Inrequent-Access]]：EFS 不频繁访问层，适合很少访问的文件
|
||
- [[S3-Intelligent-Tiering]]：S3 智能分层，自动根据访问模式移动数据
|
||
- [[FSx-for-NetApp-ONTAP]]：AWS 文件存储服务，支持自动分层
|
||
- [[Lifecycle-Policy]]：生命周期策略，自动转换存储层
|
||
|
||
## Key Entities
|
||
- [[ADM]]：一家公司，通过多次迁移最终使用 FSx for NetApp ONTAP 实现 60% 成本降低
|
||
- [[AWS]]：亚马逊云服务提供商
