容器世界的
FinOps
容器，以及一些可能占用剩余服务器资源的可突增
Pod
、尽 量
Pod
，从而用尽所有备用容量。
服务器实例费率优化
除非你使用无服务器集群（我们接下来将对此进行研究），否则你的集群将由常规云服
务器实例组成。
如果你的集群运行了大量尽量或可重新启动的
Pod
，则可以选择使用
Spot
实例运行部分
集群。
Spot
实例可能会帮你节省大量成本。但是，在集群中运行它们需要考虑额外的风险，
即你的服务器实例（以及它们正在运行的
Pod
）可能会被云服务提供商在几乎没有通知
的情况下停止。
可以像任何其他实例一样预留这些服务器实例。运行了像
Kubernetes
这样的集群编排引
擎，并不意味着需要从正常的预留和承诺计划中排除你的集群。通常，我们看到容器化
会带来更稳定的云服务器实例。容器可以随时启动和停止，无须更改整个云服务器。这
可能意味着更简单的预留计划和更好的整体预留利用率。预留一直运行的实例可以节省
50%
以上，正如我们在第
13
章中所讨论的那样。
容器运营阶段
在本部分内容中，当你经历一个扩展的
FinOps
运营阶段时，你应该考虑在云资源级别
执行的操作中有多少可以应用于容器世界。安排在工作时间打开和关闭开发容器，查找
和删除空闲容器，以及通过强制使用的标签来维护容器的分类管理，这些正是你可以从
扩展的
FinOps
运营阶段中得出的一些可借鉴之处。
无服务器容器
由
AWS Fargate
等云服务提供商提供的无服务器容器，为你的
FinOps
容器策略增添了
有趣的变化。使用自托管集群时，需要考虑运行更多集群的成本影响。管理每个集群的 ...
