基于成本收益分析的云计算环境下数字图书馆建设研究

Research on Digital Library Construction under the Cloud Computing Environment Based on Cost-benefit Analysis

文章首先分析了亚马逊弹性云计算以及其可划分的云计算资源,然后研究了基于云计算模式下数字图书馆的带宽、计算资源与低成本特性,以及作为云计算技术保障的虚拟化技术。最后,给出了最大化成本效用的计算资源管理与规划方案。通过资源的精细化管理以及自动负载分配技术,进一步降低数字图书馆云计算平台成本,提升了成本效用。

This paper introduced Amazon Elastic Compute Cloud and its resizable compute capacity in the cloud at first. Then, this paper analyzed the bandwidth, computing resources, the character of low cost and virtualization technology of digital library under cloud computing environment. Finally, this paper gave out the maximized cost utility solution of computing resource. Refinedmanagement and auto-workload server will reduce cloud cost and improve cost utility.
