总结
预留实例和承诺使用折扣是云用户可用的最复杂的优化。通过成功的预订计划可以获得
很大的折扣。
总结如下 ：
●
三大主要云服务提供商都能提供以预定换取较大的折扣。每一个都有不同的功能、
工作方式，以及提供的折扣。
●
为了从预订中获得最大的好处，你需要了解所有的功能，包括大小的灵活性和购
买后可以进行哪些修改。
●
由于所有这些复杂性，你必须确保集中管理预留实例和承诺使用折扣，以便团队
可以专注于减少使用率，而不是担心费率。
●
因为预留实例经常被误解，所以教导不同的利益相关者团队（比如工程团队和金
融团队）是过程中的重要一步。
现在你已经了解了预留实例的工作方式，接下来我们将讨论在组织内部正确实施预订的
策略。
