Why use a virtual host? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

Virtual host uses special software and hardware technology to divide a real physical computer host into multiple logical storage units, each of which has no physical entity, but each physical unit can work on the network like a real physical host, with a separate domain name, IP address (or shared IP address) and complete Internet server functions.

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

By using the virtual host technology, a real host can be divided into many "virtual" hosts, each of which has an independent domain name and IP address and a complete Internet server (www, FTP,email) function. Virtual hosts are completely independent, and in the outside world, each virtual host is exactly the same as an independent host. The effect is the same, but the cost is very different. As multiple virtual hosts share the resources of a real host, the hardware costs, network maintenance costs and communication line costs borne by each virtual host user are greatly reduced, and Internet has really become an affordable network for everyone!

At present, many enterprises use this method to set up websites, which not only greatly saves the cost of purchasing machines and renting dedicated lines, but also does not have to worry about the technical problems of using and maintaining servers, let alone hiring specialized management personnel. because we take care of all these things.

If the resources of one machine are allocated to multiple virtual hosts, will the performance of each virtual host be degraded?

This problem depends on the performance of the host and the number of virtual hosts set up. If properly configured, coupled with the use of high-bandwidth lines, virtual hosts will be faster than independent hosts connected with lower-bandwidth lines. The number of users of each host will be controlled within a certain range, which can protect the interests of users while making full use of the performance of the host.

How to choose a virtual host

First, the length of time of operation.

The length of operating time is an important criterion to evaluate a virtual hosting provider.

Second, high performance-to-price ratio.

Low prices lead to performance degradation low prices to prevent service providers from losing excellent reputation, excellent quality, sincere service, the right price, for a successful web hosting provider, none of these can be missing.

Third, don't be greedy for cheap.

The virtual host is divided into multiple hosts by the server through the virtual host technology. generally speaking, it is normal to place less than 200 enterprise websites or less than 30 functional websites on the server, which will not affect the speed of the server; if you exceed this number, no matter how good the server is, it is difficult to bear, resulting in a decline in speed and frequent failures.

Fourth, online management function.

It is best for service providers to provide online management functions such as virtual host control panel, FTP and so on. There are many virtual host management software supporting various platforms in the market, which makes the management of virtual host space easier and more humane.

Fifth, household PC as a server.

It is particularly important to note that many swindlers use home PC as servers and ADSL as access. The stability and speed of this kind of space are quite poor, so don't be greedy for such petty bargains.

Sixth, data security.

Whether the service provider provides firewall equipment to protect users' data security and prevent DDOS attacks. Whether there are other illegal websites on the server, and if there are other illegal websites on the service, it may cause the whole server to stop running.

Seventh, whether it is perfect after sale.

Whether the service provider has perfect after-sales service, monitor the user's data, and avoid being punished by the communication management department and the public security department. For example: China Wanwang, Valley Interconnection, etc., which are formal ISP access providers, website space service providers, hardware firewalls, monitoring and other equipment, with the above advantages.
