What is VPS Server? All You Need to Know About VPS

If you are looking for a comprehensive article about VPS. We want to answer your question about what a virtual server is in simple language and introduce you to different types of servers and hosting services.

VPS, which stands for Virtual Private Server, is a virtual and private computer with high-speed internet that is on 24 hours a day, and you can access it at any time and from any location. The virtual server is a part of the server resources that are separated by a virtualizer and provided to users in a completely dedicated way with the desired operating system; Virtual server offers features and capabilities similar to a dedicated server, But it is more economical than that.

VPS, with flexibility, scalability, and good security, is a smart choice for users who want to start an important activity with the lowest cost and the best performance and capabilities.

VPS has different types according to its function, such as a virtual server for Windows, Linux, Mikrotik, etc. In the following, we will thoroughly explain the definition of a virtual server, Its types, and its applications. And We will talk about the advantages and disadvantages of VPS and how VPS works, management and control of VPS panels.

What Is A Server?

To better understand what a VPS is, it is best first to understand the concept of a server; The definition and meaning of a server in many people’s minds when buying hosting services becomes Bold and challenging for them.

The server is a powerful and always-on computer that users expect to respond to their requests at different times and store information and data uploaded to the site. Generally, servers are the most important communication factor in the network.

If the access to the server is only within the scope of an internal network, It is called a network server, and all the computers connected to this network will be under the control of the server and will Provide their web-based needs with its help.

But if we know that this network consists of all the computers that are connected through the Internet, we are faced with a larger group of computers that are turned on and available through the Internet. The Internet server provides users with the information searched on the Internet bandwidth around the clock.

If we want to explain this subject completely, the Internet is a vast network of computers located around the world; Two computer systems create a network by communicating and exchanging information with each other.

As you know, every system has a specific address for access and identification, and by connecting to the Internet, they join its large network. They are receiving services or Servicing with their unique address on the Internet.

In this network, some systems are servicing; By entering the site address in the browser, The contents and information of the site are located in the system on which the web server is installed. A site may contain a lot of information, or many users worldwide may be connected to this site; Certainly, this site can not be supported by a simple computer.

As a result of the server as a Service Provider, In the large Internet network by sending information to the browser at any time of the day; Provides users with the content of the site that you have allowed to display and hosts your users well.

Now that you are fully acquainted with the definition of a server, we will define a virtual server.

What Is VPS Or Virtual Private?

VPS or Virtual Private Server is a small unit of server that is divided into smaller sections using the virtualization technique of a dedicated server. With the help of virtualization, a virtual version can be created from any physical server hardware; in other words, a powerful piece of hardware can be converted into multiple servers using software and virtualization.

It is excellent to have several separate servers on a dedicated physical server with different operating systems and independent resources such as RAM, CPU, etc.

For example, a virtual server is like a small unit of a building where you can rent that space for different purposes and use all the space and resources of that unit separately. Still, the hallway or elevator to access your unit (VPS) can be shared.

As we explain, VPS is a portion of a more extensive physical server but with less price than a complete physical server. Depending on the resources that you choose, the location of the server,  the virtualization technology, and the quality of your service, the price of your VPS will change.

Because VPS separates your data and OS from other VPS servers, it is really private! All of the resources inside VPS are dedicated except the bandwidth, which is shared between all VPS servers on the same physical server.

However, some providers define a specific amount of bandwidth for each plan of their VPS services. VDS is the same as a VPS, and it is the summary of a virtual dedicated server. Most of the operating systems can be installed on this service like Windows, Linux, and Mikrotik. As the owner of the VPS has superuser & admin access, running any configurations and installing any apps or software is possible.

VPS resources are always upgradable to have a more powerful server. Most of the VPS hosting companies provide services in monthly, quarterly, semi-annually, and annually periods. Until you renew the service before the expiration date, your VPS will be kept for you.

I have heard of most of the users which ask what should be their operating system and resources to connect to VPS, I should say that it is not important what your own operating system is, or if your own laptop or computer is powerful or not, the only thing you should prepare is a good internet connection to have the best quality of connection to the VPS. if you have a good Internet connection, you won’t face lagging when using VPS.

Also, it’s better to choose the nearest location of the server to your own location to have the least ping rate, I should say the gift of a less ping is a smoother connection for you! And finally, VPS means, you don’t have to rent the street, you can rent a house on that street!

What Is Bandwidth?

Network bandwidth measures the maximum capacity of a wired or wireless communication link to transmit data through a network connection over a period of time. Bandwidth is the data transmission capacity of a computer network in bits per second (Bps).

Typically, bandwidth is displayed in the number of bits, kilobits, megabits, or gigabits that can be transmitted in 1 second;  In other words, bandwidth is the total amount of download and upload traffic and their speed and network capacity; It should be noted that bandwidth is not a factor for measuring the speed of the network and it only has the task of measuring the information that is transmitted in the network by communicating between two devices; But the amount of data that is being exchanged affects the efficiency of a transmission medium, such as an Internet connection.

For example, consider a street, If the road is wide, cars (an example for data) can pass smoothly, but if it is narrower, you will see heavy car traffic, and Cars will be harder to pass. This example states that bandwidth will belong to all existing virtual servers on the network and can be shared.

But you can get dedicated and reserved bandwidth with the help of virtualization technology and server administrator authority.

What Is A Data Center?

The data center is one of the most important physical centers globally. Too many computer servers and network equipment perform uninterrupted computing, storage, and data transfer operations.

Servers have powerful networks and hardware that consume a lot of power and generate a lot of heat that can not be maintained in a normal situation such as home because of the need for strong infrastructure and conditions for server maintenance.

Data centers provide the necessary conditions for maintaining servers. Data centers are standard locations that are highly resilient to natural disasters, have very high-bandwidth Internet infrastructure, and often have advanced security systems, ventilation, firefighting, and power distribution systems that provide emergency power systems (UPS and Diesel generators) are equipped to avoid problems.

Implementing a data center is generally based on a vast processing and storage resources network that, With the help of a powerful communication infrastructure, allows the provision of intranet services (local and intra-organizational) or Internet data transmission on a large and small scale.

The topics we explained have been for your familiarity with the data center, but this article aims to provide more important issues about the virtual server. But understanding the importance of the geographical location of the data center when purchasing a VPS and understanding the concept of the data center is somewhat necessary.

How To Create A Virtual Server?

As explained above; In order to create a virtual private server, several virtual servers are created by dividing a dedicated server with the help of virtualization technology. By sharing a dedicated server and its resources, we have a virtual server with features similar to a dedicated server and more affordable. The server administrator can provide dedicated resources for each section based on customer needs.

To better understand VPS, we gave an example of a large residential complex as a server and its units as a VPS. And each VPS has its own secure and dedicated space; Which means you will have a server with a dedicated hard drive, RAM, and CPU.

as people can make changes in their units In VPS, management is also the responsibility of the manager, and with ROOT or Administrator access, you can manage the security and speed you need without the intervention of other sources, And also have your favorite operating systems such as Linux or Windows.

As a result, in the same way, that we explained, you can use the features of the virtual server and have a secure virtual server with the desired operating system and administrator access without the need for initial server configuration.

Definition Of Virtualization

Virtualization uses hardware and hardware resources, including memory, CPU, disk, network card, etc., in a computer system to set up and use (host) more than one operating system simultaneously.

To use a system and its hardware, you need to install an operating system to manage the system; Virtualization helps you install and manage multiple operating systems on one hardware or server at the same time, and you can maximize productivity with minimal cost.

Virtualization is the technology and software infrastructure that replaces the operating system on servers and systems and is a virtual example of hardware that Simulates a physical computer for a host of multiple virtual computers. It also runs on a separate partition of the host system with the desired operating system, memory, CPU power, and other items.

It should be noted that virtualization systems are available for free or not free for different operating systems, depending on their type and function.

On the server, Virtualization is used for partitioning to turn a single server into multiple virtual servers, each running its own desired operating system. The server also needs to support virtualization technology. In this case, a server can be used in different ways and purposes, and instead of performing a specific task, Have optimal performance and also save money.

Basic VPS Infrastructure Based On Virtualization Technology

Most virtualization infrastructures are Linux-based, and most hosting companies use Linux-based virtualization infrastructures and VMWARE and KVM; After getting acquainted with virtualization technology, familiarize themselves with some examples of virtualization infrastructure:


Xen isThe fastest and most professional open-source virtual machine in the world of information technology. Xen hypervisor is based on Linux software, and In addition to Debian, Xen Virtualization supports Solaris, which is a version of Linux.

In any aspect, it is an intelligent choice because it is compatible with both Linux and Windows operating systems and does not require an operating system; You can install it directly on the hardware. Xen is light virtualization that plays an essential role in optimizing system and server resources because it takes up less RAM and space. This virtualizer is not free and is mainly used in specialized organizations.


Esxi Virtualizer is the latest version of VMware hypervisor that runs directly on hardware without the need for an operating system like Xen. Esxi, with its dedicated user panels such as VCenter, enables the management and optimization of infrastructure and server integration. Also, some of the management panels for this software are installed as modules in the hosting companies’ user panels and are available to users.

With the help of these management panels, users can access the console of the virtual server and various monitoring sections, turn the server on or off, and restart it. As a result, using Xen increases access and improves management, providing more security.

Other benefits include reduced physical infrastructure costs, high stability, highly advanced fault tolerance systems, Flexibility of activities, ease of upgrading and updating, and support for remote developers.


It is one of the best and most widely used free virtualizers that creates various Linux virtual systems and servers. One of its disadvantages is that it only supports the Linux operating system.


Virtualization is Linux based and free but requires special non-free panels to communicate with the user panel. This virtualizer has a user-friendly environment, and users and server administrators can have remote access to different parts of the virtual server by having its panels, and you can turn the server on and off and have all the steps of the boot server. ; The most popular of these panels are SolusVM and AutoVM.

KVM is used as an electronic switch for switching between servers. Its features include high speed, dedicated resources, the ability to view bandwidth consumption and VNC console online, fast installation and automatic delivery of virtual server operating system, The possibility of changing the operating system of the virtual server at any time by the user, and the user, sharing a keyboard and monitor with several different systems and the possibility of better monitoring of the user on the virtual server.

Virtual Server Applications

Virtual server has many wonderful uses; we will mention their most essential applications in the following:

To point out the applications of Windows Virtual Server, we can mention the most important reasons for choosing it because of fast data transfer and managing Forex trades; In contrast, one of the most important applications of the Linux virtual server is to create a web server, create a proxy server and even build a game server!

  • Hosting websites

Most users use shared services to host their websites, but if they have a large, high-traffic, growing site, Over time, they encounter serious problems, and also shared hosting will not meet the site’s needs. In this situation, the best choice is virtual servers with a lower cost than a dedicated server and similar features to a dedicated server.

The most common use of VPS is for sites with high traffic and number of visits and require more storage space and more powerful CPU than a shared hosting server; also, by buying a VPS, you can be sure of the security and speed of your site.

Sites that need to use VPS and shared hosting will not work well for the needs of the site:

  1. Store sites with many products and customers, and their transactions are high.
