The Internet is changing the world. It has contributed to the formation of the embryonic form of the network economy. As a new communication media, the Internet has the characteristics of great communication capacity, diverse forms, rapid and convenient, global coverage, freedom and interaction. Therefore, almost all enterprises and institutions around the world have established their own Web sites.
(1) The virtual host adopts the virtual host technology to divide a computer host into several virtual hosts. Each virtual host has an independent domain name, an independent shared IP address, and a complete Internet server function. From the outside, each virtual host performs exactly the same as an independent host. Users can use it to establish their own WWW server, FTP server and E-mail server. The virtual host is generally provided by the ISP, which accesses to the Internet through the ISP's dedicated line. The ISP is responsible for the hardware maintenance, system software configuration, network monitoring and other technical work of the virtual host. The user is responsible for preparing the web page and updating the data through remote login. Since multiple proposed hosts share the information of a real host, the hardware cost, network maintenance cost Communication costs are low. Generally, according to the difference in web space (IOOMB-2GB), mail space (5OMB-1GB), system software support, etc., the annual cost is about 500-10000 yuan. The virtual host mode can only simply publish information, and cannot build a background database or develop its own system. If the enterprise has limited funds, insufficient technical strength, low functional requirements, and low security requirements, this mode can be considered.
(2) The server hosting service specially borrows the server hosting, that is, the user rents the ISP rack to place the user server, and accesses the Internet through the ISP special line. The hardware configuration, system software, Web pages, etc. of the server are all set by the user to be responsible for the computer room environment and network environment of the server's safe operation 24 hours x 7 days. The user maintains the server and updates data through remote login. In general, ISP charges for this method regardless of traffic, hard disk space and access times. The cost of user hosting only depends on the height of the server and connection bandwidth. Generally, 1U, 2U, 4U, 7U servers are connected to the IOM switch port of the ISP machine room. The monthly fees are 1000150025004500 yuan respectively; The monthly fee for connecting to the OOM switch port is 1500 yuan and 200030005000 yuan respectively. Two domain names and one IP address are provided for free. Although this method can publish information, build a background database and develop your own system, it is obvious that the system and database are directly exposed to the Internet and lack of security. In addition, it is not convenient to expand the rules of the site.
(3) Dedicated line access refers to the user connecting the website service to the Internet through a dedicated data line (such as DDN dedicated grave). The user can apply to the local data communication bureau or ISP providing this service for a dedicated data line at the corresponding rate. The special access mode is adopted, and the user's service is specially placed in the computer room. The user should have the corresponding hardware and software configuration, strong computer and network technical force, and be responsible for the management, maintenance and data update of the server. The general purpose of special access to China's public computer Internet is: 64 and 128 kB/s special lines. The monthly fee for information flow is 5400 yuan and 7300 yuan respectively, and 10 and 20 MB/sa special lines. The monthly fee for information flow is 139000216800 yuan respectively. This way can not only release information, build a background database and develop your own system, but also expand the scale of the website in an unconventional way according to the needs of business and information release. At the same time, a firewall can be set to ensure the security of the website.
These three methods have their own advantages and disadvantages, and are suitable for different user needs, Website Design First, the purpose of building the station should be clear. For different purposes, websites of different sizes and natures can be selected. If the user has limited funds, insufficient technical strength, low functional requirements, and low security requirements, the purpose of building a website is only to establish an enterprise image and publish some advertisements, so we can consider choosing a virtual host. If the user has sufficient funds, strong technical strength, high functional requirements, and high security requirements, the website can provide dynamic interaction functions. When conducting online transactions, we can consider selecting dedicated lines for network access. Server hosting can be said to be a way between dedicated lines for network access and virtual hosts. In practical application, the website can be set up in the way of virtual host to realize some functions of e-commerce. When the requirements and conditions are improved, the server hosting or special line access can be used to improve the website operation and service level and gradually realize all functions of e-commerce.
