A lot of companies provide a VPS server for rent. At the same time, prices differ so much from different firms that, sometimes, you don't know who to go to. It is very important to know what a VPS is, why you need it, and what it gives the user.
VPS is translated from English as “virtual private server”. “Private” means “dedicated”. It is sometimes called that: VDS - Virtual Dedicated Server. These 2 abbreviations mean essentially the same thing.
What exactly? VPS is an intermediate "link" between shared hosting and dedicated server. If your web project is cramped on shared hosting, but it is too early to rent an entire server, then you need a virtual dedicated server.
VPS is obtained by dividing a dedicated server into smaller servers by software or hardware. This division is called virtualization.
As a result, the user gets a separate server, which is not physical, but has all the properties of a physical server: a certain processor, a certain amount of memory, a certain amount of hard disk, and an operating system. VPSs come in both Windows and UNIX-like operating systems.
Why do you need a VPS? Well, for example: your site requires non-standard software settings that cannot be performed on shared hosting. The most important thing is that on your server you are your own master, since only you have access to the system with super-administrator (root) rights. Therefore, you can install any version of any software. This is a freedom that can never be achieved on shared hosting, due to its specifics.
