摘　　要：网格资源只能在某个高峰段被充分利用,缺少云计算资源随任务个数增多,按需拓展的优点。而云计算的弹性拓展会受到云的硬盘容量的限制,在负载井喷的情况下依然会资源匮乏。人们试图赋予网格弹性拓展特点的同时,让云能够调度高性能的网格资源。通过整合双方的优势,互补对方的不足,在网格和云现有的资源上创造更为强大的计算能力。这里分析了现有集成方案的通用框架,以及网格云集成的主要任务调度策略,并建议用私有云与网格集成,以避免现有网格云集成的安全问题。The grid resource can only be fully utilized during certain busy hours, this different from cloud computing with elastic characteristics. However, the cloud＇ s elasticity is limited due to its maximum hardware capacity. The cloud would still fall short of the demand when cloud burst comes. People try to give elastic characteristics to the grid, and let cloud dispatch the grid resources of high performance. By integrating both sides＇ advantages and remedying both sides＇ deficiencies, a more powerful computating capacity based on the existing resources of grid and cloud is produced. This paper analyzes the common framework of existing integrated solutions, including the main-task scheduling strategy of grid-and-cloud integration, and suggests the integration private cloud and grid, thus to avoid the security problem of the existing grid-and-cloud integration.
