What are three kinds of virtual hosting technologies?

This article will explain in detail about which three kinds of virtual hosting technology, the content of the article is of high quality, so the editor will share it for you as a reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

There are three kinds of virtual host technology: URL name correspondence (Name-based), IP address correspondence (IP-based) and Port port number correspondence (Port-based).

Virtual host technology can realize that the server can be divided into multiple virtual hosts, and each virtual host can run independently.

So what is the implementation principle of virtual hosting technology?

There are three main components: the virtual machine manager, the virtualization stack, and the new virtual Icano model. The Windows virtual machine manager is mainly used to create different partitions, and each virtualization instance code runs within its own partition. The virtualization stack and the Iamp O model are used to provide interaction with the Windows itself and the various partitions created.

These three components coordinate with each other. The server in the virtual host has a processor equipped with Intel VT or AMD-V-assisted technology, and the virtual host uses this server to interact with the virtual machine manager. The virtual machine manager is a small level of software that is directly reflected in the processor. The software hooks threads in the processor, so that the host operating system can run on a single physical processor to effectively manage multiple virtual machines and multiple virtual operating systems.

About which three kinds of virtual hosting technologies are shared here, I hope the above content can be of some help to everyone and can learn more knowledge. If you think the article is good, you can share it for more people to see.
