What is a virtual server and what does it do?

Virtual Server VPS stands for Virtual Private Server. A virtual server is part of a complete dedicated server. This is done with virtualization. In this way, a server is divided into several sections that are used for different purposes. Due to the fact that the resources of a complete server are divided into several parts, often and under the same conditions, the cost of purchasing a virtual server is lower than a dedicated server. In this article, we will fully discuss the virtual server and explain its applications. Please stay tuned.

What are the uses of a virtual server?
Virtual server has many uses and it can be used many times. The following are some of them:

Hosting a relatively high-consumption website or a number of medium-consumption sites
Use a virtual server for web services such as mail server, database server and…
Use a virtual server to control or improve system performance
Use of virtual server as secondary communication agent and data encryption
Using the services of sites that have imposed sanctions on Iran. Of course, if the IP is abroad
Doing things that require high-speed Internet with high traffic.
And dozens more…

Explain the process of preparing a virtual server
Depending on the technology and structure of virtualization, virtual servers are usually derived from one or more dedicated servers. Typically, multiple virtual servers are derived from a single dedicated server. To do this, virtualization requires an agent (virtualization software). Virtualization systems are available for free or for different operating systems, depending on their type and function. The server also needs to support virtualization technology. There are a number of specific solutions for creating a virtual server as Local or Public. For example, for each virtual server on the web, at least one IP must be considered in order to register it on the network. Non-virtualization systems can be configured individually or shared for each virtual server based on the number of CPU cores allowed, the amount of virtual RAM, the amount of hard disk volume, and so on. Dedicated or shared resources means that each server has the right to access resources in a completely dedicated way or can use shared resources in a shared way. Usually in shared mode, high quality and performance can not be expected. In the following, we will mention some of the virtualization technologies and operating systems supported by it.

Virtuozzo virtualization model
OpenVZ virtualization model
VMware virtualization model
Xen virtualization model
KVM virtualization model
And …

Each of the virtualization models has one or more special features that you can research….

Types of virtual servers
Virtual servers are usually categorized based on operating system, virtualization model as well as its technology. The following are the types of virtual server categories:
Linux virtual server (with the possibility of installing a variety of Linux distribution operating systems)
Windows Virtual Server (with the ability to install most Windows server operating systems)
Dedicated virtual server (with completely dedicated resources such as CPU, RAM and…)
Shared virtual server (with shared hardware resources)
Virtual cloud server (with a different structure to increase the level of performance, stability, security and…)
There are other categories that were mentioned as the most important and widely used.
