## Summary
多账号策略是 AWS 推荐的企业级云架构模式,通过将工作负载分离到多个 AWS 账号来提升安全性、治理能力和故障隔离。
## Definition
Multi-Account Strategy多账号策略是指在 AWS Organizations 框架下,使用多个 AWS 账号组织云资源的管理策略通常包括管理账号Management Account、日志账号Log Archive Account、安全账号Security Account和多个工作负载账号Workload Accounts
## Key Attributes
- **目的**:安全性提升、治理能力增强、故障隔离、成本核算
- **实现方式**AWS Organizations + Organizational Units (OU)
- **核心组件**:管理账号、成员账号、组织单元
## Why
- 资源隔离:不同业务线、环境(生产/开发/测试)相互隔离
- 安全边界:最小权限原则,账号间无法相互访问
- 合规要求:满足 ISO 27001、HIPAA 等合规审计需求
- 成本追踪:按账号独立核算成本
