中文摘要: 云存储服务, 作为云计算的衍生产物, 目的是为网络海量数据的存储提供有效的解决方案, 节约存储成本和系统资源, 提供一个完善的备份、容灾的数据中心, 并能够保证数据安全性、容错性. 现阶段云灾备模型局限于有限的网络位置, 使用虚拟化技术, 依托本地服务器实现, 与传统云灾备模型不同, 介绍了一种基于DHT的云灾备模型, 可适用于广域网的、普适的数据级灾备解决方案; 最后, 在本地云计算集群中对该方案进行模拟, 验证该模型的可行性.
Abstract:Cloud storage service is derivative products of cloud computing intended to provide an effective solution for mass data storage networks, while save storage costs and system resources. It can provide a complete backup, disaster recovery data center, in order to ensure data security, fault tolerance and efficient storage functions. At present, cloud disaster recovery models are using virtualization technology, which relies on the local server implementations. This paper introduces a model of DHT-based cloud disaster recovery, which is applicable to WAN universal data-level disaster recovery. Finally, in order to verify the feasibility of the model, the scheme is simulated in the cloud computing cluster.
