多云战略在带来更大灵活性和更多技术选择的同时，也会大幅增加复杂性和成本。高管应借鉴本文对几种多云战略方法的对比，做出最合理的选择。
针对云基础设施和平台服务（CIPS）的多云战略，例如，采用多家同时提供基础设施即服务（IaaS）和平台即服务（PaaS）的超大规模云提供商，为技术创新提供了最佳机会。
多云战略增加了IT的复杂性和成本，并且对用户技能提出了更高要求。虽然大多数企业机构最终都会采用多云战略，但很多企业机构并未进行周密规划便引入多家云提供商，从而造成了不必要的混乱。
多云战略还会增加云服务的直接成本。由于委托给每家提供商的业务量有所减少，多云战略实际上会降低折扣率。竞争并没有显著提高商定的长期折扣率，这与多数高管的预期相悖。
负责制定综合云战略的高管，应：
选定一家主要云战略性提供商来承担大部分IaaS工作负载并提供PaaS服务，以降低集成和运营的复杂性和成本。
如果企业机构具有两种截然不同的需求，比如同时需要新增云原生数字业务应用和进行传统应用迁移，则选择一家二级云战略性提供商，在控制整体复杂性的同时，使技术采用更符合需求。
明确单云或多云战略的目标，仅在业务需求无法以其他方式满足时增加云服务提供商。根据自身对每家提供商的支持水平，对提供商进行分级。实施明确的工作负载配置策略。
