云存储结构模型及云存储架构的比较研究

The Comparative Study for Cloud Storage and Cloud Storage Architecture Structure Model

云存储的概念是一个新的概念,它所利用的技术包括集群计算、分布式文件系统以及网格计算技术等.这些异构的存储系统通过彼此的协调、配合,构成一个虚拟的、巨大的存储系统,作为一个整体共同对外提供数据存储和业务访问功能.文章阐述了云存储结构模型,并对几种典型云存储的架构进行了比较研究.

The concept of cloud storage is a new concept, its technology, including the use of cluster computing, distrib-uted file systems, and grid computing technologies. These heterogeneous storage systems through mutual coordination, cooperation, constitute a virtual, huge storage system as a whole provides a common external data storage and business access function. This article describes the structure of cloud storage model, and several typical cloud storage architec-ture of a comparative study.
