## 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 │
└──────────────┘    └──────────────┘    └──────────────┘
                                                  ↓
┌──────────────┐    ┌──────────────┐    ┌──────────────┘
│  Monitoring  │ ←  │  Deployment  │ ←  │    Staged    │
│   & Rollback │    │   to Prod    │    │    Release   │
└──────────────┘    └──────────────┘    └──────────────┘

## Modern Release Management (ITSM 2.0)

在[[ITSM 2.0]]中，发布管理深度集成DevOps：

### 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 |
