Salt
实现自动化
Salt
是一款功能强大的框架，旨在作为一种极快的轻量级通信总线，提供诸如自动化配
置管理、云供给、网络自动化、事件驱动自动化等能力，以便实现基础设施的现代网络
运维。
Salt
非常
灵活，就像本章中介绍的其他工具一样，你可以用

架构
从架构角度来看，
Salt
被设计为一个具备可插入接口的简单核心。你在本节中会看到，

的网
络设备。说到底，
Salt
可用于自动化任意类型的网络设备。
Salt
在开
发之初采用的是基于代理的架构，但这种架构并不能很好地适用于网络自动化，
究其原因，是因为在所有类型的网络设备上加载软件代理并非易事。事实上，对传统网络
设备而言，这颇为困难，甚至不可能实现。鉴于对无代理自动化解决方案的需求，
Salt
更
新了其架构，同时提供了无代理和基于代理的解决方案。此外，无论选择哪一种部署方
式，
