What Is A Virtual Private Server And What Does It Do?

I had a problem a few months ago and my solution was a bit unusual. The problem was that people were asking for help with system and infrastructure problems, which of course is somewhat natural because an IT writer is dealing with people who have different problems.

I indeed like helping people, but when the volume of requests increases, it becomes more difficult to organize things. What company did I work with this week and what were their requirements?

What should I do about magazine articles? And What does the CEO expect from me and what problems do the writers face? It seemed that, like large organizations that use the Help Desk to track customer support requests, I needed a similar mechanism.

A solution that allows people who ask for help to respond quickly, get things done, and interact with colleagues in the easiest way possible.

So I decided to install on my personal server, one of the most powerful solutions in this area.

This can be a daunting task for most people because you have to do a lot of work to get a system that is useful for tracking tasks.

Setting up a website that can receive and track requests, make conversations via website email, and implementing a mechanism to log in and respond to requests and dozens of other small tasks is no longer an easy task, except that your computer should always be on And be connected to the Internet.

Otherwise, when you send answers and receive feedback, how are you able to access them, and more importantly, do all this work for free?

Undoubtedly, the implementation of such a mechanism does not end in one day, and if you are a professional, you may be able to implement it in a week. Of course, provided you skip your meals and sleep!

The most ideal option in this field, which can respond to a wide range of requests, is a virtual private server. A mechanism that gives you unlimited power.

Web hosting in front of virtual private servers

For many years, companies and even individuals spent large sums of money on hardware and sharing space, called shared web hosting space on servers. Typically, an Internet service provider provides businesses and users with space on their servers so that companies can use that space to host the services they need, such as email, databases, software, and, on a larger scale, their hardware (shared space). And manage business processes.

 To clarify, let’s compare this technology to a large shopping mall that has large booths that individuals or companies run to sell their personal products. In the above method, the applicant rents the required space from the store owner so that he can sell his products inside the booth.

 In this case, the person is responsible for managing the booth.

There is a similar rule in the world of shared web hosting. The web hosting company provides you with the space and tools you need to manage your website, however, because the server is shared with hundreds of other users or companies, you can make a lot of fundamental changes. You are not and cannot install custom software. For many people, this model is enough.

However, as business and technology grow, more and more limitations of this mechanism become apparent. It was not until early 2005 that virtualization software came up with a more cost-effective and powerful solution, meaning that companies or individuals with their own physical servers would be able to install the virtual servers they needed.

The difference between a virtual server and a web host is that the virtual server gives the impression that you have your own computer. You can control what software you install on it, and the physical server owner can allocate some of the disk space, memory usage, and CPU usage to your virtual server.

In fact, you have a separate computer inside a larger computer.

 To you who own a virtual server, it seems like you have full access to a system. A system that you can implement every month instead of paying tens of millions of tomans for physical infrastructure at a low cost.

However, the above method also has drawbacks. The disadvantage of this method is that you are responsible for doing the things or things that happen. While a web hosting contract may stipulate that the owner of the physical server is committed to troubleshooting the software, backing up the data, or ensuring that the software is up to date, the owner of a virtual server must assume these responsibilities.

 This approach is very similar to the one I mentioned at the beginning of the article, you rent a store in a mall that its preparation, maintenance, cleanliness, and safety tips are up to you and all you have to do is pay the price. Is.

What is a Private Virtual Server?

VPS stands for Virtual Private Server. Advances in technology have made it possible to host multiple virtual servers on each super server, each with its own operating system and environment.

Virtual Private Server is ideal for companies, organizations, and sites that need more resources to provide their services. A virtual server is a boundary between a shared hosting service and a dedicated server.

In a shared hosting service, a large number of websites are hosted on one server, and in return for a dedicated server (Dedicated Server), it is necessary to spend more money, which will not be economical without providing a financial justification.

VPS allows root access and installation of system software.

 Using technology such as Xen, ESXi VMware, or Virtuozzo, and using powerful and advanced hardware, a physical server is divided into several VPSs with the same or different features. A virtual server is sometimes referred to as VDS (Virtual Dedicated Server).

Virtual server hosting, with its superiority in features and resources over shared hosting service and a better price than dedicated server service, is suitable for most important and high-traffic sites.

A virtual server is used to manage sites as a web hosting space or to take control of another website remotely or to implement and execute specific code or software on a server. For example, to use a virtual server as a hosting space for a website, you must use a virtual server with Linux operating system. Virtual servers typically use Linux and Windows virtualizers or operating systems.

The Windows Virtual Server user interface is just like the Windows desktop on your home computer; With the same features and shape, it depends on the type of Windows that is installed on it.
