【摘要】：数据副本管理是云存储系统的一个重要组成部分,对提高系统的可靠性和性能具有重要意义。一般而言,云计算环境中数据副本数目越少,其传输成本则愈大;而副本过多,存储成本又随之增加,可能导致总成本上升。从降低数据管理成本的角度,在权衡存储成本与传输成本的基础上研究面向最小成本的数据副本管理策略,主要包括:数据管理成本模型、创建副本必要性测试以及近似最小成本的副本布局策略等。以Amazon云平台数据管理成本模型为例进行实验,结果表明:面向最小成本的副本管理策略在满足用户响应时间等需求的同时,可以有效地降低数据中心的管理成本,推动企业(用户)积极运用云计算平台管理企业数据,促进云计算环境的和谐发展。
[Abstract]:Data replica management is an important part of cloud storage system and has great significance to improve the reliability and performance of the system. In general, the fewer replicas of data in cloud computing environment, the higher the transmission cost; With the increase of storage cost, the total cost may rise. In order to reduce the cost of data management, this paper studies the minimum cost oriented data copy management strategy based on the balance between storage cost and transmission cost. It mainly includes: data management cost model, the test of the necessity of creating replica and the replica layout strategy of approximate minimum cost, etc. Taking the data management cost model of Amazon cloud platform as an example, The results show that the minimum cost oriented replica management strategy can effectively reduce the management cost of the data center and promote the enterprise (user) to actively use cloud computing platform to manage enterprise data while meeting the needs of user response time and so on. Promote the harmonious development of cloud computing environment.
