面向云计算的数字图书馆虚拟资源管理机制和调度策略研究

Study for Virtualized Resource Management Mechanism and Schedule Strategy of Digital Library for Cloud Computing

资源管理是云计算环境下数字图书馆的核心问题。本文首先分析了云计算资源的特点与资源管理的主要功能,给出了云计算资源管理的工作流程。然后基于云计算虚拟化技术,提出了一种云计算环境下数字图书馆资源交付与调度策略。该策略可以有效减少资源空闲时间,能够保证虚拟资源有较高的可用性和利用率。

Resource management is the core issue for digital library based on cloud computing. Firstly, the paper intro- duced the characteristics of cloud computing resource and the main function of resource management, and it presented the work flow of cloud computing resource management. And then presented a resource provision and schedule strategy for digital library based on cloud computing using vimmlization technologies. It could effectively reduce the resource idle time, and guarantee the availability of virtualized resources and enhance the virtualized resource utilization.
