## Overview
|
||
|
||
Spot Instances（竞价实例）是 AWS 提供的按需计算容量，价格基于供需动态调整，可比 On-Demand 价格低 60-90%。适用于容错、可中断的工作负载。
|
||
|
||
## Use Cases
|
||
|
||
- 批处理作业
|
||
- CI/CD 构建
|
||
- 大数据分析
|
||
- 机器学习训练
|
||
- 容器化工作负载（配合 Spot Instance Interruption Handling）
|
||
|
||
## Best Practices
|
||
|
||
- 实现优雅关闭处理（Graceful Shutdown）
|
||
- 使用 Spot Fleet 或 Spot Block（固定时间段）
|
||
- 结合 Auto Scaling Groups 实现弹性
|
||
- 与 On-Demand 或 Reserved Instances 配合用于核心工作负载
