5 摘要:随着数据的暴增,传统的存储方式已经不再满足海量数据的存储需求,云存储技术的
飞速发展,使得云存储成为了一种新型的数据存储解决方案。本文分析了国内外云存储技术
的发展现状,提出了一个具有高可扩展性、高可靠性、兼容不同存储设备的分布式云存储解
决方案。本文从分布式文件系统 HDFS 出发,设计实现文件读写模块,在兼容 Amazon S3
协议的基础上,设计实现核心业务逻辑处理模块、面向前端请求的代理模块、安全认证模块、
10 基于数据库的元数据存储模块、前端页面显示模块,构建高可扩展、高容错、可靠、安全的
分布式云存储系统,并完成了整个云存储系统的分布式部署和测试。

20 Abstract: With the explosion of data,Traditional storage methods no longer meet the massive data
storage requirements.The rapid development of cloud storage technology makes cloud storage
become a new type of data storage solutions.This paper analyzes the development status of cloud
storage technology at home and abroad,and then puts forward a distributed cloud storage solution
which has the characteristics of high scalability, high reliability, and compatible with different
25 storage devices.Based on the Distributed File System HDFS and Amazon S3 protocol,this paper
designs and implements file read-write module,core business logic processing module, agent
module for front-end request, security authentication module, metadata storage module based on
database , the front page display modu
