SRE
与
DevOps
的关系

是什么，用了多长时间得到这个反馈等。无论是从专业角度，还是从理念角度看，
DevOps
和
SRE
都是以数据为基础的。
•
现实是残酷的。管理生产服务，意味着随时都会发生糟糕的事情，因此你不得不
去调查原因。
SRE
和
DevOps
都推行对事不对人的事后总结，从而避免发生那些
毫无建设性的互相指责。
•
最终，实践
DevOps
或
SRE
是一种整体行为；两者都希望通过特别的方式共同合

虽然作为一个职业，
SRE
非常了解激励机制及其影响，但却很少涉
及各自为政、信息孤岛等话题。它支持
CI
和
CD
并不一定是因为具体的业务逻辑，
而是因为运维实践得到了改进。或者换句话说，
SRE
与
DevOps
所认可的东西相同，
但认可的原因略有不同。
因地制宜才能事半功倍
在工作理念上，
DevOps
和
SRE
有很大的相似之处。正如你所知，它们需要一组很相 ...
