## Definition
Standard Change标准变更是一种预批准的变更类型无需变更咨询委员会CAB的审批。在理想的 DevOps/SRE 实践中,标准变更应实现完全自动化,通过 IaC基础设施即代码+ CI/CD Pipeline 实现。
## Characteristics
|| Attribute | Value |
|-----------|--------|
| Approval Required | 否(预批准) |
| CAB Involvement | 无需 |
| Automation Level | 完全自动化IaC + CI/CD |
| Risk Level | 低(已知变更,已评估) |
| Change Window | 无限制 |
## Implementation
标准变更的实现依赖于以下技术栈:
1. **IaC基础设施即代码**Terraform/Terragrunt 声明式定义基础设施
2. **CI/CD Pipeline**Jenkins/GitHub Actions 自动执行 plan/apply
3. **Automated Testing**:在部署前自动验证基础设施变更
4. **Tagging Standards**:符合 AWS 标签规范,确保 Checkpoint 防火墙正确放行
## Example Use Cases
- AWS 标签验证Tag Validation Tool自动扫描资源合规性
- VPC 自动化供给Topic 61CIDR ≤ /22 自动审批
- 标准 AMI 更新Topic 50自动构建和发布
## Relationship with Other Change Types
```
Standard Change ──(通过自动化提升)──→ Normal Change
CAB 审批
有风险影响
Emergency Change ──(CAPA 修复根因)──→ Standard Change
立即执行
```
## Goal
将尽可能多的变更归类为标准变更,通过自动化减少人工审批负担,提高变更频率和可靠性。
