同行评审
当我们谈论传统软件意义上的同行评审时，通常说的是应用程序的源代码。开发人员会向
一些源代码文件提交包含差异的补丁，补丁会以某种方式发布到代码审查系统中，审查员
会查看该补丁并提供意见或批准。
将管道这部分用于网络自动化时，我们并没有偏题太远。本书的其他几章（比如第
5
章和
第
6
章）
提倡网络自动化采用“基础设施即代码”的方法，在这种方法中，所有相关的配
置信息都按照开发人员对待源代码的方式来处理。在我们的例子中，不会出现
Java
代
码，
可能会有
Y
AML
文件或
Jinja
模板。它们都只是文本文件，我们同样可以对其执行自动化
测试。
如果维护过任何形式的生产环境
IT
基础设施
，那么你应该参加过变更批准委员会
（
Change
Approval Board
，
CAB
）。你可能负责填写表单，在其中描述要进行的配置变更，
然后参加漫长的电话会议，做一番精心措辞的简单发言，以求让审批人员满意。这套流程
在现代
IT
中根深蒂固
，但它并不能
真正
将风险降到最低，也无法在相关技术团队之间提
供透明度。这都是老派的做法了。
在谈论用于网络的
CI
时
，我们会从同行评审的概念着手，这可能看起来与上面描述的情景
类似，但还是有一些根本区别。在
CI
中
，如果你想做出变更，那么只需在
Git
中创建一个
新分支并进行改动即可。通过在作为
CI
管道组成部分的
Git
仓库中执行配置
，不需要事先
请求许可，因为在完成评审及合并入
master
分支之前，变更并不会被推送到生产环境。
这种新模式有一些颇具吸引力的好处。在同行评审方面，现在无须再“描述”要做的变 ...
