## Definition
|
||
|
||
发布管理（Release Management）是[[ITSM]]的核心流程之一，负责**规划和协调软件从开发到生产的整个发布过程**，确保高质量、低风险的版本交付。
|
||
|
||
## Release Management Process
|
||
|
||
```
|
||
┌──────────────┐ ┌──────────────┐ ┌──────────────┐
|
||
│ Release │ → │ Build & │ → │ Testing & │
|
||
│ Planning │ │ Package │ │ Validation │
|
||
└──────────────┘ └──────────────┘ └──────────────┘

┌──────────────┐ ┌──────────────┐ ┌──────────────┘
|

### DevOps-Integrated ITSM
|
||
|
||
| 实践 | 描述 |
|
||
|------|------|
|
||
| [[Canary-Release]] | 渐进式流量转移 |
|
||
| [[Blue-Green-Deployment]] | 零停机双环境部署 |
|
||
| Feature Flags | 特性开关控制 |
|
||
| Automated Rollback | 自动回滚 |
|
||
|
||
### Progressive Delivery Patterns
|
||
|
||
```
|
||
Traditional: v1.0 → v1.1 → v1.2 (Big Bang)
|
||
Canary: v1.0 → [v1.1 → 5%] → [v1.1 → 20%] → v1.1
|
||
Blue-Green: Blue[v1.0] ←→ Green[v1.1] (instant switch)
|
||
Feature Flags: v1.0 + [Flag:NewFeature=ON] (dynamic control)
|
||
```
|
||
|
||
## Key Metrics
|
||
|
||
| 指标 | 描述 |
|
||
|------|------|
|
||
| Deployment Frequency | 部署频率 |
|
||
| Lead Time for Changes | 变更前置时间 |
|
||
| Time to Market | 上市时间 |
|
||
| Release Success Rate | 发布成功率 |
