管理单位经济学：
FinOps
涅
可以看到，活跃用户的增加，同时增加了云支出。在此指标中，业务价值（活跃用户）
是根据云支出来衡量的。
图19-3 引入免费套餐产品期间的每月活跃用户和公司云成本
只有把云支出与公司收入的对比更改为与每月活跃用户、预订的航班座位或跟踪的运输
活动等指标的对比，这种数据洞察才更有效，因为后面这些指标更能反应与云支出之间
的关系，而不是公司收入。当你使用的单位与组织的收入没有直接关系时，调整向客户
收取的价格不会更改单位指标值。当你使用这些指标时，衡量云平台创建的业务吞吐量
（尤其是与云支出相关的业务吞吐量）将成为围绕云成本效益做出业务决策的关键要素。
回到铁三角
单位经济为团队提供了他们所需的数据，使用北极星指标可以衡量基础架构的变化如何
影响成本。运营团队和财务部门之间的对话不再是关于变更细节，而是更多地关注变革
将产生的影响。这允许业务部门做出决策，权衡调整的好处和对单位成本的预期影响，
例如，将每个活动用户的成本提高
2%
是否会将应用程序性能提高
10%
。
当你将单位经济性应用于
FinOps
生命周期的优化阶段时，你的目标由仅使用运营指标
（如达到
80%
的
RI
覆盖率）升级到使用影响收入的目标（如将每个订阅用户的成本降低
25%
），此时你对成本的管理更加成熟。前者可以帮助业务，但它也可能分散对真正重要
事物的注意力。
