What is Virtual Hosting?

Virtual hosting (English: virtual hosting) or shared web hosting (also known as virtual web server ) is a method of implementing multiple domain services on a single host or host group, which can run multiple websites or services. technology. Virtual hosts are completely independent and can be managed by users themselves. Virtualization does not mean that there is no existence, but that the space is extended from the physical server. The hardware system can be based on a server group or a single server.

Virtual host technology is a technology used by Internet servers to save server hardware costs. Virtual host technology is mainly used in HTTP (Hypertext Transfer Protocol) services. It logically divides one or all services of a server into multiple services. The service unit is externally represented as multiple servers, thereby making full use of server hardware resources.

The virtual host uses special software and hardware technology to divide a real physical server host into multiple logical storage units. Each logical unit has no physical entity, but each logical unit can work on the network like a real physical host, with a separate IP address (or shared IP address), an independent domain name, and a complete Internet server (support WWW, FTP, E-mail, etc.).

The key technology of the virtual host is that even if different server programs opened for multiple users are running on the same hardware and the same operating system, they do not interfere with each other. Each user has a part of his system resources (IP address, file storage space, memory, CPU, etc.). Each virtual host is completely independent. From the outside, each virtual host behaves exactly the same as a separate host. So this kind of virtualized logical host is called "virtual host".

There are three main implementation methods: Name-based, IP-based, and Port-based.

• Hardware facilities of the host

• The virtual host computer room owned by the virtual host provider, what size of the data center, whether there is sufficient bandwidth of the computer room line, and whether the speed of the online connection of the virtual host website meets the traffic bandwidth of all his virtual host customers.

• How many websites are hosted on web hosting

• Generally, a virtual host can host hundreds to thousands of websites. If the number of websites is larger, the more people share the same server; in comparison, resources are tighter. Generally related to the machine's CPU, memory, etc. IIS is generally 10,000 / connections per server.
