VPS

The Internet is a huge network of computers located all over the world. When we connect two computer systems and exchange information between them, these two systems together form a small network. In the Internet, all computers in the world are connected to each other with cables and have a specific address for identification and access. When it is said that you are connected to the Internet, it means that your system is also connected to this large network and you are serving or receiving services with a specific address on the Internet.

In this large network, some systems act as servers. For example, when we open a website in a browser, the content of the website is located on a system in the Internet network on which the web server is installed and the information of the website is placed on it. This website may have stored a lot of information or many users in the world have connected to this website. So this website cannot be on a simple computer system.

When the physical server hardware is divided into different parts virtually with virtualization software, servers with independent and limited resources are created. These servers are called private or dedicated virtual servers. This service has the same features as a dedicated server with more limited capabilities, and its cost is lower than a dedicated server.

The total consumption of download and upload traffic (Traffic) and their speed is called bandwidth. We already said that virtual server is like renting a unit of a big building; So, to access it, you have to cross several streets to reach that unit.

If we consider the streets to access the same network cables, we can say that the number of cars crossing the street is “traffic” and the width of the street is “bandwidth”. So the wider the street, the more people can cross the street and reach your building at the same time.

In the meantime, the important point is that the end of the street or the network cable ends at the building or your server, not your unit, which is your virtual server. So, in a virtual server, it is natural that the network is shared between all the virtual servers in the host server.

For example, if the host server’s network is 1 GB, everyone uses this network; Unless there is only one virtual server on the host server that uses all the bandwidth exclusively. Of course, with the methods that the virtualizer provides to the server manager, you can have dedicated and reserved bandwidth. You should contact support or your server administrator to confirm this.

Among the advantages of VPS, we can mention the following:

• Affordable cost compared to a dedicated server
• The possibility of root access to the server and its configuration according to needs
• The ability to change server resources in a completely simple way
• More security and speed compared to a shared server or host

Although the use of VPS does not have many disadvantages, the following disadvantages can be considered as the weaknesses of this type of server compared to other servers:

• Compared to shared servers and hosts, it is more expensive.
• Server configuration is usually difficult; Therefore, if you plan to manage the server yourself, you usually need to have knowledge of coding in the server environment.
• Compared to a dedicated server, it has fewer resources.

• Dedicated powerful hardware
• High monthly traffic and unlimited bandwidth
• High speed SSD hard drive
• Dedicated and fixed IP
• Ability to manage the server and reboot
• Ability to upgrade the server after purchasing a virtual server

Types of virtual servers are classified based on different factors. One of these factors is the type of operating system used in these servers. In the following, we list the types of virtual servers and briefly explain one of them.

• Linux virtual servers
• Windows virtual servers
• Mikrotik virtual servers
