What is VPS? How Does VPS Work?
A VPS or Virtual Private Server, as its name suggests, is a virtual machine (VM) acting as a server on the internet.
A VPS can host a version of an operating system that can be remotely controlled from essentially any other device that can be reached. This is somewhat similar to web hosting servers that contain all the data of a particular website that can be displayed from either internet-connected desktops or laptops, except that a VPS can directly host a desktop computer.
Although several VPSs are created on one computer, they can function independently of each other. A certain amount of CPU power, space, RAM, and transfer allocation is guaranteed for you every month. In short, a VPS is a cloud-based desktop PC.
There are many uses for a VPS, particularly for organizations and individuals who need to remotely access their computers instead of having to carry the devices wherever they go.
VPS (Virtual Private Server)-
Now consider VPS, instead of sharing server bandwidth and resources with dozens of accounts, you can have it all for yourself and use it as you wish.
In VPS you have your own space on a physical server that is partitioned into multiple private environments. The technical term for this is visualization. So while others may reside on the same physical server as you, your space is yours alone, and you don’t share resources. Same as dedicated hosting, VPS hosting allows a high degree of control and customization. You can change server settings, install software, add users, and even turn the server off if needed.
In general, VPS hosting is more affordable than dedicated hosting. It’s a good solution when you want your server and resources, and the control of dedicated hosting, but, you don’t need the amount of space and power that dedicated hosting provides.
Depending on how hands-on you want to be, you can use two different types of VPS:
1. Managed VPS hosting: particularly ideal for those who don’t know how to run a server on their own. This type includes the installation and management of server and server applications.
2. Unmanaged/ self-managed VPS hosting: only includes switching your server on, the rest is on you. This one is ideal for those who have an in-house IT team.
A VPS, also known as a virtual private server, is a server running on a virtualized operating system with other virtual servers. Each server is unaware of the others, but they all share the same system resources, such as CPU, disks, and network bandwidth.

Virtual private servers are often operated by Internet hosting services. Users can lease servers which are "virtually private" — nothing else shares the operating system. Usually, greater resources can be allocated to the server for an additional cost.
The host which operates the VPS service benefits by using fewer machines, and by managing the virtual servers at a high level using a hypervisor. For instance, server creation and removal can be automated, making it trivial to activate (or deactivate) hundreds or thousands of servers at once.
