云计算平台中对象存储的数据同步方法研究 摘要 随着云计算的快速发展，以及数据产生速度的不断提高，各种云计算平台和应用对信息存储的要求也越来越高。包括亚马逊、谷歌和IBM在内的很多互联网巨头都投入到对云存储系统的研究中。 本文通过分析OpenStack平台的云存储系统Swift，在对该系统进行分析的基础上，了解云存储系统中对象存储技术的使用，以及对象存储系统中同步各类数据的方法。 同时本文使用了一定的篇幅详细分析了Swift存储系统中客户端与系统的数据传输，并研究了存储系统内维护对象的一致性而进行的同步，基于此提出可配置副本存储方案在数据同步方面所需要进行的设计开发。 在上述工作的基础上，通过修改Swift的部分源代码，调整系统的配置结构和业务逻辑，实现可配置副本的存储方案。 最后，基于云存储系统的应用环境对设计的系统进行分析，讨论该系统在不同情况下的工作方式并给出系统API调用的方法示例，评估系统在实际应用环境中的表现。 关键词：　云存储，对象存储，对象同步，一致性 Abstract With the rapid development of cloud computing, as well as the continuous improvement of the data generation, a variety of cloud computing platforms and applications for information storage requirements are also increasing. Many Internet giants, including Amazon, Google and IBM are put into the cloud storage system. In this paper, we analysis the OpenStack cloud storage platform system Swift. Based on analyzing the system, we try to understand the using of cloud storage system and object storage technology. At the same time, we use a detailed analysis of the data transmission and the client of the system in the Swift storage system, and research the synchronization for the sake of consistency maintenance of the object storage system. Then, we study the design of a configurable copy storage scheme for the data synchronization. On the basis of the above-mentioned work, we modify the Swift part of the source code, adjust the configuration of the system structure and business logic to design and develope the configurable storage solutions. At last, we analyse the system based on storage system application environment for the design, discuss the way of working on the system in different circumstances and give the example for a method of system API calls to assess the performance of the system in actual application environment. Key Words：　Cloud Storage, Object storage，Object Synchronization，Consistency. 目录 摘要 i Abstract ii 图目录 IV 表目录 V 第1章 绪论 1 1.1 研究背景 1 1.2 研究现状及发展趋势 1 1.2.1 国外云存储技术发展现状 1 1.2.2 国内存储技术发展现状 2 1.
