论文摘要
云计算是一个通用术语，涉及通过Internet提供托管服务。随着应用程序使用的数据量的加速增长，许多组织已将其数据转移到云服务器中，以提供可扩展，可靠和高度可用的服务。在具有地理分布的数据复制的云存储系统中出现的一个特别具有挑战性的问题是如何达到所有副本的一致状态。这项调查回顾了与云数据存储系统中一致性问题有关的主要方面，将最近提出的方法分为三类：（1）固定一致性方法，（2）可配置的一致性方法和（3）一致性监视方法。
Cloud computing is a general term that involves delivering hosted services over the Internet. With the accelerated growth of the volume of data used by applications, many organizations have moved their data into cloud servers to provide scalable, reliable and highly available services. A particularly challenging issue that arises in the context of cloud storage systems with geographically-distributed data replication is how to reach a consistent state for all replicas. This survey reviews major aspects related to consistency issues in cloud data storage systems, categorizing recently proposed methods into three categories: (1) fixed consistency methods, (2) configurable consistency methods and (3) consistency monitoring methods.
