## Definition
|
||||
S3 Intelligent Tiering(S3 智能分层)是 AWS S3 的一种存储类,可自动根据对象访问模式在不同的存储层之间移动数据,无需用户干预即可实现成本优化。
|
||||
|
||||
## Key Features
|
||||
- **自动监控**:自动监控访问模式,识别不频繁访问的数据
|
||||
- **无转换费用**:在不同存储层之间移动时无需支付转换费用
|
||||
- **两层监控**:30 天无访问移至 Infrequent Access,90 天移至 Archive 或 Deep Archive
|
||||
- **支持所有对象大小**:适合任何大小的对象
|
||||
- **无检索费用**:从任何层检索数据无需支付费用
|
||||
|
||||
## Pricing Model
|
||||
- 存储费用根据层级不同:
|
||||
- Frequent Access:标准 S3 费率
|
||||
- Infrequent Access:比标准层低约 40%
|
||||
- Archive Instant Access:比标准层低约 70%
|
||||
- Deep Archive:比标准层低约 95%
|
||||
- 监控费用:每 1,000 对象 $0.015/month
|
||||
|
||||
## Use Cases
|
||||
- 日志文件归档(访问后 30 天内不访问)
|
||||
- 数据湖中的冷数据
|
||||
- 合规性保留数据
|
||||
- 备份文件的长期存储
