云联盟是解决随机突发流量问题的理想方案之一。它的核心是在本地云即将过载时向外部云"借用"计算资源，在本地云空闲时向外部云"租赁"资源。考虑到业务价值对于云提供商的重要性，我们需要执行一些明智、合理和简单的规则或机制来帮助云提供商在联邦范围内做出更好的计费决策并提高整体性能。云联盟是通过网络连接来实现的，因此在通常情况下，最佳的候选云可以享受到更高的连接速度。这仍然是一个问题，即位于子网中的多个云有很大的可能性相互联盟，因此它们之间会出现复杂的依赖关系。本文通过在云联盟的建立和解构过程中实施一系列的动态资源安排机制，来梳理这些对云联盟整体性能有潜在风险的依赖关系。
Cloud Federation is one of the ideal solutions tothis random burst traffic problem. It focuses on 'borrowing'computing resources from foreign Clouds when home Cloud isabout to overloaded and 'leasing' resources to foreign Cloudswhen home Cloud is free. Considering crucial importance ofbusiness value for a Cloud provider, we need to perform somedynamic, reasonable and simple rules or mechanisms to helpCloud provider making better billing decisions and improvingthe overall performance in a federation scope. Cloud Federationis implemented by network connections, so in common situationthe best candidate Cloud to be federated enjoys a higher speedof connection to the home Cloud. This remains a problem thatseveral Clouds located in a subnet have a high possibility to befederated with each other, thus complicated dependency relationsamong them will appear. In this paper, we have carried out aseries of mechanisms involving dynamic resource arrangement inestablishment and deconstruction of a Cloud Federation, in orderto sort out these dependency relations which are the potentialrisk factors to the overall performance.
