Today, I would like to talk to you about what the server and virtual host are, many people may not know much about it. In order to make you understand better, the editor has summarized the following for you. I hope you can get something according to this article.

The server provides computing or application services for other clients (such as PCs, smartphones, ATM terminals and even large devices such as train systems) in the network. The server has high-speed CPU computing ability, long-time reliable operation, strong external data throughput and better expansibility. Virtual host, also known as virtual server, is a method to achieve multi-domain services on a single host or host group, which can run multiple websites or services. Virtual hosts are completely independent and can be managed by users. Virtual does not exist, but means that the space is extended from the server of the entity, and its hardware system can be based on the server farm, or a single server.

According to the services provided by the server, generally speaking, the server has the ability to respond to service requests, undertake services, and guarantee services. As an electronic device, the internal structure of the server is very complex, but it is not much different from the ordinary computer internal structure, such as: cpu, hard disk, memory, system, system bus and so on.

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, etc.). Each virtual host is completely independent, and in the outside world, the performance of each virtual host and a separate host is exactly the same. So this kind of virtualized logical host is vividly called "virtual host".

Is the server the same as the virtual host?

The server is different from the virtual host, the server contains the virtual host, but the virtual host cannot become a server. The server can be divided into many virtual hosts through virtualization technology, and each virtual host has certain server functions. Virtual host can only achieve part of the server functions, mainly in the web application, can not bear the complete functions of the server.

Shall we buy a server or a virtual host?

This is mainly based on the requirements, for example, if you need higher server permissions and special requirements for the environment and software, it is recommended to buy a server; if you only build a website and the requirements are not high, you can use a virtual host, which is more cost-effective.

After reading the above, do you have any further understanding of what servers and virtual hosts are? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
