跨云联盟（CCF）支持多个异构云服务提供商（CSP）之间的资源交换，以支持由不同提供商托管的服务（工作流）的组合。CCF参与可以是固定的，或者可以使用的服务类型是有限的，以减少服务失败或安全访问的潜在风险。尽管云计算文献中提出了许多服务选择方法，但它们对CCF的适用性，即，云与云之间的交互尚未得到充分研究。这种云到云模式的一个关键组成部分涉及评估联盟内贡献参与者的组合能力及其连接性。提出了一种新的聚合能力评估（AgCA）的基础上使用的共识评估倡议问卷的云安全联盟的CCF。所提出的机制作为集中式代理的一个组件来实现，以提高联邦内参与者的选择过程的质量。我们的实验结果表明，AgCA是一个有用的工具，在一个动态的，异构的和多级云联盟的合作伙伴选择。
Cross-Cloud Federation (CCF) enables resource exchange among multiple, heterogeneous Cloud Service Providers (CSPs) to support the composition of services (workflow) hosted by different providers. CCF participation can either be fixed, or the types of services that can be used are limited to reduce the potential risk of service failure or secure access. Although many service selection approaches have been proposed in literature for cloud computing, their applicability to CCF i.e., cloud-to-cloud interaction, has not been adequately investigated. A key component of this cloud-to-cloud paradigm involves assessing the combined capability of contributing participants within a federation and their connectivity. A novel Aggregated Capability Assessment (AgCA) approach based on using the Consensus Assessment Initiative Questionnaire from Cloud Security Alliance is proposed for CCF. The proposed mechanism is implemented as a component of a centralized broker to enhance the quality of the selection process for participants within a federation. Our experimental results show that AgCA is a useful tool for partner selection in a dynamic, heterogeneous and multilevel cloud federation.
