在
Google
，每个
SRE
团队都有两个主要目标：
短期
通过提供可运作的稳定系统来满足产品的业务需求，该系统不仅可用，还可根据
需求扩展，并着眼于可维护性。
长期
将服务运维优化到不再需要目前所执行的人工工作的水平，因此
SRE
团队可以
继续开展下一个高价值工作。
为此，团队应商定一些合作原则，例如：
•
运维工作的定义（以及硬性限制）。
•
服务的已达成共识且可度量的

商定的季度错误预算，用于确定发布速度和其他安全参数，例如用以应对意外使

•
开发人员参与日常运维工作，以确保他们也可以看到持续存在的问题，并确定修

规划与执行
主动计划和协调一致的执行在确保
SRE
团队达到预期目标和产品目标的同时，也优
化了运维，并降低了运维成本。我们建议在两个（关联）层次进行规划：
•
与开发人员的领导一起，确定产品和服务的优先级，并发布年度路线图。
•
定期回顾和更新路线图，并努力实现与路线图一致的目标（季度或其他的）。
