Robson A. Campêlo, Marco A. Casanova, Dorgival O. Guedes, Alberto H. F. Laender

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迁移到云服务器中,以提供可扩展,可靠和高可用的服务。在具有地理上分布式的数据复制的云存储系统的上下文中出现的特别具有挑战性的问题是如何使所有副本达到一致的状态。本调查回顾了云数据存储系统中与一致性问题相关的主要方面,将最近提出的方法分为三类:(1)固定一致性方法,(2)可配置一致性方法和(3)一致性监控方法。

英文摘要:

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.
