面向云计算的数字图书馆动态迁移关键问题及优化

Key Problems and Optimization for Live Migration of Digital Libraries in Cloud Computing

文章首先研究了云计算及在线迁移技术,然后,从动态资源配置角度对迁移的收益进行讨论。利用云的资源动态性、按需分配特点,提出了一种新的数字图书馆动态云迁移策略。该策略可实现传统数字图书馆系统平滑迁移到云计算环境,具有经济、高效、安全的特点。

Based on the research of cloud computing and live migration, we study the migration bentits trom the perspective ol dynamic resource allocation. By considering the cloud features such as dynamics resources and distribution according to need ,we proposes a new live cloud computing migration solution for digital library which can realize the smooth update from the traditional digital libraries to the cloud computing environment and has been proved to be feasible and has some advantages, such as low cost, high efficiency and secur- ity. 6 refs.
