云计算存储技术分析摘要随着网络应用业务量的不断增长,云存储技术作为云计算系统的重要应用之一,也得到了更多的关注
对云存储技术的讨论实质上是讨论分布式存储技术
不同于传统的存储体系,云计算存储技术需要解决更多的数据以及运算的负载,需要保证更好的数据可用性以及数据一致性,需要提供更快的系统响应时间
针对这些需求,各大公司都开发出可以很好的解决方案,本文主要针对主流的云存储系统(Google File System、 Amazon Dynamo 等)进行分析,主要分析其在冗余备份、动态扩展、负载均衡等方面的解决策略
关键词:云存储, 冗余备份,动态扩展,负载均衡AbstractAs with the rapid growth of web application , cloud storage is getting more and more attention
In fact, research on cloud storage is essentially research on distributed storage technology
Distinguished from conventional storage system, distributed storage technology needs to better support enormous amount of data and computing workload , guarantee better data availability and integrity, and provide shorter system response time
To meet those requirements , lots of giant companies have come up with great
