互联网数据中心(Internet Data Center:IDC)作为一个名词已逐渐被人们所熟悉,但从字面上看,它又是一个模糊不清的概念。它不是数据存储的中心,而是数据流通的中心,它应该出现在Internet 巨大的网络中数据交换最集中的地方。它是伴随着人们对主机托管和虚拟主机服务提出了更高要求的状况而产生的,某种意义上说,是由 ISP 的服务器托管机房演变而来。以往人们只需要一台稳定的服务器和一定的机房空间,甚至只是一定的硬盘空间就可以满足自己网站运行的要求,而在电子商务风行和企业电子化的刺激之下,人们对硬件和空间的简单要求上升为对服务和管理的更高要求,于是,数据中心宣告诞生。从国内情况看,目前经营IDC 业务的企业大概有三种类型。第一类是电信运营商,如中国电信以及网通,它们在运营数据中心的同时,也是很多二级 ISP 商的带宽提供者;第二类是一些具备较强实力和超前市场意识的传统 ISP 公司,如世纪互联、首都在线,这些企业拥有多年积累的品牌资源,并且重视市场宣传;还有就是一些传统的 IT 企业投资兴建数据中心,如清华万博等。我们这次主要从中选出了世纪互联、网通、首都在线和清华万博这四家作为代表,分别从它们对IDC 业务的认识理解以及对各自数据中心业务的介绍的角度作一些分析。我们也选出了北新数码作为用户方谈了对数据中心业务的认识,以及美国服务器托管市场分析,希望能对准备开展数据中心业务的企业和借助数据中心开展电子商务的企业带来帮助。综合各家的观点,我们首先对数据中心业务产生的背景、数据中心的实质及它在 IT工业中所处的位置等作以下阐述。
As a term, Internet Data Center (IDC) has gradually become familiar, but literally, it is a vague concept. It is not the center of data storage, but rather the center of data distribution, and it should appear where data exchange is most concentrated in the vast Internet network. It comes along with people placing higher demands on hosting and hosting, in the sense that they evolve from ISP hosting servers. In the past, people only needed a stable server and a certain computer lab space, and even a certain amount of hard disk space could meet the requirements of their website operation. In the e-commerce popularity and the stimulation of the electronic enterprise, Simple requirements rose to higher requirements for service and management, so the data center was announced. From the domestic situation, the current business IDC business about three types. The first category is telecom operators, such as China Telecom and China Netcom, which operate data centers as well as bandwidth providers for many second-tier ISPs. The second category is the traditional ISP companies with strong capabilities and advanced market awareness , Such as Century Internet, the capital online, these companies have accumulated over the years the brand resources, and the emphasis on marketing; there is some traditional IT companies invest in building data centers, such as Tsinghua Weber. This time, we mainly selected Century Internet, China Netcom, Capital Online and Tsinghua Huambo as representatives, and analyzed them from the perspectives of their understanding of IDC business and the introduction of their respective data center business. We also selected Beixin as a user to talk about our understanding of data center business and the analysis of the server hosting market in the United States, hoping to help companies preparing for data center business and enterprises conducting data e-commerce through data centers. From the individual point of view, we first describe the background of the data center business, the nature of the data center and its location in the IT industry.
