When exploring hybrid cloud solutions, the provision of cloud computing resources by more than one provider, may result in important gains, such as better risk management, improvement of operational efficiency and avoidance of the lock-in effect by a single vendor. To this end, many enterprises decide to rely on hybrid strategies and multiple cloud providers. With the strategic distribution of the cloud management and resources between multiple providers, multi-cloud adoption can achieve greater efficiency, taking advantage of the economies of scale, and establish an optimal performance/cost balance of the multi-cloud service. Into this context, the paper explores the pricing strategies of 23 different providers for IaaS and estimates the efficiency of different multi-provider service bundles, utilizing DEA methodology. The results are quite encouraging, since the efficiency of multi-cloud solutions is increasing, while cost savings may be accomplished. They provide a measurable driver for clients exploring hybrid solutions of how to mix different IaaS services of different providers.

在探索混合云解决方案时，一个以上的提供商提供云计算资源可能会带来重要的收益，例如更好的风险管理，提高运营效率以及避免单个供应商的锁定效应。为此，许多企业决定依赖混合策略和多个云提供商。通过在多个提供商之间进行云管理和资源的战略性分配，多云的采用可以利用规模经济实现更高的效率，并建立多云服务的最佳性能/成本平衡。在这种情况下，本文探索了23个不同的IaaS提供商的定价策略，并利用DEA方法估算了不同的多提供商服务捆绑的效率。结果令人鼓舞，因为多云解决方案的效率不断提高，同时可以节省成本。它们为客户探索如何混合不同提供商的不同IaaS服务的混合解决方案提供了可衡量的驱动力。
