构建
RI
策略的步骤
构建第一个
RI
策略有
5
个关键步骤 ：
1.
学习基础知识。
2.
构建一个可重复的
RI
流程。
3.
定期及长期购买。
4.
衡量有效性，不断迭代。
5.
合理分配
RI
成本。
在本节中，将依次介绍每个步骤。
学习基础知识
通过第
13
章的学习，你已经了解了
RI
的基本原理。
但是，第
13
章有两个概念还没有介绍。一个是
RI
的盈亏平衡点，另一个是
RI
基准线
（
Waterline
）。请你记住这一点 ：
在谈到 RI 预留周期时，一年不是一年，三年不是三年。
是的，你承诺为这段时间付费。但是，为了使购买具有经济意义，不需要实际使用这么
长时间。
即使是最忠诚的云用户，三年的承诺期似乎也很可怕。在某些方面，它与云的一切优势
背道而驰 ：即时、可扩展、按量付费。但是，云服务提供商的一年或三年承诺期，可以
节省大量资金，并彻底改变云的经济价值。
一年期
RI
可能在短短
4~6
个月内实现盈亏平衡，而三年期
RI
可能在短短
9~12
个月内
实现盈亏平衡。在组织中共享有关这些盈亏平衡点的数据，有助于减轻对所选择的承诺
