The virtual server is relative to the physical machine. It is used widely by enterprises and organizations to take full advantage of the processing power. Compared to a data center, the virtual server is easier and less expensive to own and manage.

What Is a Virtual Server
A virtual server (also known as web server) refers to the server that is able to share software and hardware resources with other operating systems; there is a big difference between a virtual server and a dedicated server (also called dedicated hosting service). In recent years, the virtual servers become more and more popular, especially in Web hosting environments. That is mainly because the virtualization server is more cost-effective; besides, its resource control is much faster than that of dedicated server.
What is virtualization?
It is actually a technology that allows you create a software-based or virtual version of something, such as virtual computer hardware platforms, virtual applications, storage devices and computer networks. Virtualization works efficiently to optimize processing power usage and lower the overall IT costs.

Classification of Virtualization
In general, there are 4 unique types of virtual servers based on different versions of virtualization.
1. Server virtualization.
The first type of virtualization is server virtualization, which will put the entire physical server into the virtual environment. It helps to greatly reduce the number of servers required by emulating a dedicated physical server.
2. Desktop virtualization.
The OS virtualization means to put your desktop’s operating system into the virtual environment and keep it hosted on a server. The certain OS only has one version on the physical server; other copies of it for each virtual server are offered to different people.
3. Storage virtualization.
You can also use virtual servers to store information or put some physical hardware together & place them into a single virtualized storage environment. This is called cloud storage and it can be divided into private, public, or a hybrid of both.
4. Hardware virtualization.
Hardware virtualization is also known as real machine virtual. It is usually a computer with an operating system to work like a real machine. The software is kept on the physical machine but it is separated from the hardware resources.
What Is Server Virtualization
What is server virtualization? It simply means that people can apply the virtualization technology to servers via special methods. Your computer can be split among two or more virtual machines, instead of dedicating to running the server software, by making use of virtual servers.
Advantages of Server Virtualization
You can gain some benefits from server virtualization by running many operating systems, programs, and applications on a single server.
- Make the most of processing power.
- Make the infrastructures simpler and more efficient than before.
- Deploy the applications and programs correctly at a fast speed.
- Increase the performance, availability, and something else of your server.
- Reduce the overall cost of IT since virtual machines can be sold as a service; their price is much lower than that of a dedicated physical server.
All in all, the virtualization server makes your deployment & management easier and less expensive than ever.

Types of Server Virtualization
There are 3 main types of server virtualization that people can use to divide a physical server into several virtual servers (virtualization manager is needed).
1. Full virtualization.
A hypervisor is required to work as a special kind of software for allocating resources reasonably; it communicates directly with the physical server and can serve as a platform for the operating system of each virtual server.
Para-virtualization is very different from full virtualization; the guest or virtual servers in it know the existence of each other. Unlike full virtualization, not much processing power is required for hypervisor to manage virtual servers. This will help to prevent the decreasing of performance.
3. OS level virtualization.
The architecture of OS level virtualization is completely different from the previous two types. In this kind of virtualization, a hypervisor is not needed at all. Why? That is because the virtualization capability is included in the host OS.
