Its technology is adopted by Internet server to save the hardware cost of the server. Virtual host technology is mainly used in HTTP, FTP, EMAIL and other services. It logically divides one or all service contents of a server into multiple service units, which are externally represented as multiple servers, thus making full use of server hardware resources. If it is a system-level division, it is called a virtual server.

Extended data:
The key technology of virtual host is that even if different server programs run for multiple users on the same hardware and operating system, they will not interfere with each other. And each user has his own part of system resources (IP address, file storage space, memory, CPU, etc. ). Each virtual host is completely independent. From the outside world, each virtual host and a single host behave exactly the same. Therefore, this virtualized logical host is vividly called "virtual host".
