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

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 |
