过大是非常必要的。这是因为今天正确使用资源的服务可能在部署了更高效的服务代码
之后，明天就可能是过度配置的。甚至客户行为的改变也会降纸容量的需求。

研究表明，有两种类型的云团队 ：一种忘记了他们的一些资源，另一种撒谎说忘记了他
们的一些资源。换句话说，资源被遗忘并留在云账户中是很常见的。
寻找浪费可以通过挖掘成本非常稳定的部分和过时的资源（墨守成规或一成不
变并非云服务应有的运行方式）来实现。
告诉团队不要忘记，资源并不能涵盖所有方面。有可能一个资源是由自动化程序创建的，
但没有按设计去自动删除它。或者这些资源是团队故意留在那里很久很久，没有采取任
何后续行动。此外，一些资源配置在父资源被删除时保留，比如附加到服务器上的卷，
当删除一些资源时，云服务提供商可以自动创建数据的快照，无论你是否需要它。
资源丢失或遗忘是团队最容易遇到的问题。这种情况下的优化策略可以是简单地删除资

成本。
我们经常听到的另一个情况是需要将数据存储在资源中。通常，团队只能将数据保留很
长一段时间。即使你需要为这个目的保留一个未使用的容量，也有一些方法可以减少你
所支付的费用。例如，云服务提供商提供多个存储层，当你可以将数据转移到价格较低
的“冷存储”资源（如
Azure Archive
或
AWS
冰川存储）时，用高价格的存储服务产生
的费用就是浪费费用。
