减少使用：使用率优化
通过重新设计减少使用
减少资源使用最复杂的方法是重新设计服务本身。让工程团队改变软件部署的方式，重
写应用程序，甚至完全改变软件，可以帮助你利用云原生产品。
弹性
改变资源的大小并不总是解决问题的全部方法
—
资源可能在工作时间内被很好地利
用，但在工作时间之外就不行。当然，如果你将实例的大小调整为较小，那么在工作时
间内，实例将被过度使用，可能导致性能问题。
团队可以将产品服务设计得更加云化，从而使他们能够充分利用云的弹性。最常见的方
法是让服务在繁忙期间扩容（提供更多的资源），在非高峰时间缩容。服务本身需要支
持这种动态扩展，这可能需要重新设计应用程序代码。特别是对于专有软件而言，扩展
可能根本无法实现。
按计划运作
团队经常在休息的时候让开发和测试的环境继续运行。考虑一个地理上集中的开发团队，
每周使用他们的资源
40~50
小时，而其余的
118
小时完全不使用它们。如果他们能够在
一周
70%
的时间关掉开发资源，就可以为组织节省大量的资源。根据分布式团队的位置，
也至少有
24
小时每个人都在过周末。
在不需要资源时，为团队提供自动关闭资源的方法，是确保资源在非工作时间停止的最
佳方法。我们将在稍后讨论
FinOps
生命周期的操作阶段时讨论自动化。

我们经常被问道 ：“那我的预留实例呢
?
”如果有承诺预订，比如承诺使用折扣（
CUD
）
或预留实例（

），总是会担心你的使用变化导致你的预订未被充分利用。通常的解决
办法是先进行使用优化，再进行费率优化，比如预留实例或承诺使用折扣。 ...
