云计算环境中分布式数据存储关键技术研究
Research on key technologies of distributed data storage in cloud computing environment
摘要
Abstract
The cloud computing system is faced with many problems in the aspects of scalability and high availability due to the enormous node scale and data scale of cloud computing. For the distributed data storage in cloud computing environment, an regular N⁃equilateral polygon(RNEP)network model based on recursion was constructed. The data management model is given on the basis of data center network structure. The transcript distribution strategy and selection strategy were designed to improve the data availability and load balancing ability. A data migration algorithm based on covering set is proposed on the premise of ensuring the data availability,in which the node selection strategy is used to minimize the migration cost and conduct data mi⁃gration to rest more machines and reduce energy consumption. The experimental data is compared and analyzed,which proves that the proposed network topology,data management model and data migration technology are valid and effective.关键词
