中文摘要: 在多租户云计算系统中,由于云服务请求的多样性与大规模性,使得已有的云服务提供机制不堪重负,导致云服务提供商的运营成本急剧上升;同时由于云服务请求的高度不确定性,导致云服务的可靠性急剧下降,这对已有的云服务提供机制带来新的挑战。为此,本项目重点解决如何在云服务提供机制中兼顾收益和可靠性。通过对成本有效的实时云服务请求调度算法、SLA约束下利润驱动的云服务动态虚拟资源调度算法、云服务提供机制的可靠性评估算法等研究,构建一种可靠性约束下的高收益云服务提供机制,为未来的云计算平台建设提供理论支撑和技术支持。基于该研究,发表SCI论文12篇以上,Rank A/B/C类国际会议论文2篇以上。

英文摘要: In multi-tenant cloud computing systems, due to the diversity and large scale of cloud service, the existing cloud service provision mechanism cannot adapt to it, and lead to the dramatically added operation cost. At the same time, the high uncertainty leads to a sharp decline in the reliability of cloud service. All these bring new challenges to the existing cloud service mechanisms. To cope with these challenges, the study focuses on combining revenue with reliability for cloud service provision mechanism. Based on cost-effective real-time cloud service request scheduling algorithm, profit-driven virtual resources scheduling algorithm for cloud services wiht SLA constraints and reliability assessment algorithm of cloud service provision mechanism, the study intends to build a high revenue cloud service provision mechanism with reliablity constraints, which will provide theoretical foundation and technical support for the future cloud computing platform construction. In terms of the research results, 12 or more SCI papers, and 2 or more conference papers of Rank A/B/C will be published.
