电信运营商“互联网+”业务中的分布式存储技术研究

摘要

随着互联网技术的成熟，各种类型的“互联网+”业务应用得到快速发展。种类多、数量大是互联网数据的显著特点。传统存储由于其在元数据管理、访问性能、存储容量、横向扩展等方面的局限性，在进行海量小文件处理时已显吃力。为满足井喷式互联网数据存储的需求，形式各样的分布式存储系统应运而生。文章对分布式存储技术进行研究分析，对比各类分布式存储系统的优劣，结合一些典型的电信业务简要论述哪些应用适合传统存储方式，哪些应用适合分布式存储方式。希望能对电信运营商“互联网+”业务系统建设起到抛砖引玉的作用。%With the development of Internet technology, various types of “Internet+” business application services have developed rapidly. All kinds of pictures, mail, e-books, Internet Archives and other small data files are accumulating exponential y. Internet data is featured for its great variety and large quantity, while traditional storage technology is hard to deal with plenty of smal files because of its limitation in meta-data management, access performance, storage capacity and scalability. Various kinds of distributed storage systems have emerged to meet the needs of big internet data.Through the research on the distributed storage technology and analysis, as wel as some typical telecommunications services, this article compares the advantages with the disadvantages of various types of distributed storage systems, and tries to il ustrate whether the service is more suitable for traditional or distributed storage technology. Hope it to be help to the business system construction of the telecommunication operators in the area of“Internet+”services.
