Organized in associations, Cloud Computing Providers became able to negotiate the acquisition of resources from other providers at more attractive prices, while allowing the marketing of their own idle resources to the other members of the respective Inter-Cloud. However, Inter-Cloud associations are characterized as resource-sharing environments, which allow for the presence of malicious providers called Free-Riders. Free-Riders have predatory behavior, seeking to serve only their own interests and consequently harming other providers within the environment. Mechanisms to avoid Free-Riders, as well as to keep resources supply × demand balanced, are needed in Inter-cloud environments such as Cloud Federations. For example, the absence of a resource consumption control mechanism can cause a Free-Rider to consume resources in a way that is disproportionate to that offered to Inter-Cloud, referring to the problem described previously. In view of the above, this paper presents a new Inter-Cloud called MultiClouds Tournament (MCT) focused on addressing the standalone cloud providers limitations. This Inter-Cloud is inspired by the format of a soccer tournament and based on the main features of Cloud Federations. We assessed the MCT using a real workload, showing it offers an architecture that adds to the characteristics of the federations, being effective in the management of CSPs and robust in relation to Free-Riders prevention and the main strategies CSPs.

通过协会的组织，云计算提供商可以谈判以更优惠的价格从其他提供商那里获取资源，同时允许将自己的闲置资源营销给各个云间的其他成员。但是，云间关联的特征是资源共享环境，它允许存在称为“搭便车”的恶意提供商。搭便车者具有掠夺性行为，他们只为自己的利益服务，因此损害了环境中的其他提供者。在诸如云联盟之类的跨云环境中，需要避免搭便车以及保持资源供应×需求平衡的机制。例如，缺少资源消耗控制机制会导致Free-Rider以与提供给Inter-Cloud的方式不成比例的方式消耗资源，这是前面提到的问题。有鉴于此，本文提出了一种新的跨云技术，称为MultiClouds Tournament（MCT），其重点是解决独立云提供商的局限性。跨云技术的灵感来自足球比赛的格式，并基于云联盟的主要功能。我们使用实际工作负载评估了MCT，显示了它提供的架构可增加联盟的特征，可有效地管理CSP，并且在预防搭便车者和CSP的主要策略方面也很强大。本文提出了一种称为“ MultiClouds Tournament”（MCT）的新的跨云技术，其重点是解决独立云提供商的局限性。跨云技术的灵感来自足球比赛的格式，并基于云联盟的主要功能。我们使用实际的工作负载评估了MCT，显示了它提供的架构可增加联盟的特征，可以有效地管理CSP，并且在预防搭便车者和主要策略CSP方面也很健壮。本文提出了一种称为“ MultiClouds Tournament”（MCT）的新的跨云技术，其重点是解决独立云提供商的局限性。跨云技术的灵感来自足球比赛的格式，并基于云联盟的主要功能。我们使用实际工作负载评估了MCT，显示了它提供的架构可增加联盟的特征，可有效地管理CSP，并且在预防搭便车者和CSP的主要策略方面也很强大。
