可观测性与 DevOps、SRE 和
云原生的关联
到目前为止，我们已经在现代软件系统背景下引入了可观测性。因此，重要的是了解
可观测性在其他现代化实践中所扮演的角色，如
DevOps
、站点可靠性工程（
SRE
）和
云原生运动。本章会研究这些运动如何放大对可观测性的需求，并将其纳入它们的
实践。
可观测性并不存在于真空中；相反，它既是
DevOps
、
SRE
和云原生运动的结果，也是
不可分割的一部分。与可测试性一样，可观测性是这些系统的属性，可以提高对它们的
理解。可观测性和可测试性需要持续投资，而不是一次性添加，或拥有一刀切的解决方
案。随着它们的改进，作为开发人员的你和系统的最终用户都会获得好处。通过研究为
什么这些运动产生了对可观测性的需求并整合其使用，你可以更好地了解为什么可观测
性已成为一个主流话题，以及为什么越来越多的团队正在采用这种做法。
