EAGER: Towards a Marketplace for Colocation of Cloud Services

云计算正在改变我们对计算、存储和网络资源的消费和管理方式的看法；提高成本效率，并提供灵活的按需可伸缩性。沿着这些思路，本项目探索了“主机托管游戏”（CGs）作为一种新颖的、经济上合理的框架的优点，新兴的云架构可以在其上实现。cg支持对理性的、自私的各方进行交互时产生的动态进行建模和分析，以尽量减少他们为保护支持其应用程序QoS或SLA需求所需的共享云资源而产生的单个成本。cg提供了一种有吸引力的替代方案，不需要这些当事方信任云提供商（云提供商可能有相互冲突的激励），也不需要那些期望这些当事方无私或接受不能保证性能隔离的最佳努力方法的方法。除了开发cg及其变体的分析基础之外，该项目还涉及对云基础设施的一些变体的实施和实验评估，为自主、自组织系统的革命性分布式资源管理替代方案的开发铺平了道路，在这种情况下，采用全局优化方法（集中式或分布式）既不实际也不合理。这个项目涉及到从经济学到分布式系统设计的技术应用。学生在这些方面的跨学科培训促进了技术创新，这些创新不仅认识到，而且还减轻了新兴云计算架构的各种利益相关者之间的争论

Cloud computing is transforming our perception of how computing, storage, and networking resources are consumed and managed; yielding improved cost efficiencies, and delivering flexible, on-demand scalability. Along these lines, this project explores the merits of "Colocation Games" (CGs) as a novel, economically-sound framework upon which emerging cloud architectures could be implemented. CGs enable the modeling and analysis of the dynamics that result when rational, selfish parties interact in an attempt to minimize the individual costs they incur to secure the shared cloud resources necessary to support their application QoS or SLA requirements. CGs offer an attractive alternative to approaches that require such parties to trust cloud providers (who may have conflicting incentives), or those that expect such parties to be altruistic or to accept best-effort approaches that do not guarantee performance isolation. In addition to developing the analytical underpinnings of CGs and variants thereof, this project involves the implementation and experimental evaluation of some of these variants for cloud infrastructures, paving the way for the development of a revolutionary distributed resource management alternative for autonomic, self-organizing systems, in which the adoption of a global optimization approach (centralized or distributed) would be neither practical nor justifiable. This project involves the application of techniques from economics to the design of distributed systems. The interdisciplinary training of students along these dimensions promotes technical innovations that are not only cognizant of, but also mitigate the tussle between the various stakeholders of fledgling cloud computing architectures
