How VPS hosting works

Why VPS Server

In VPS hosting, every website is hosted on a virtual private server on a more powerful hardware.
So physical server is divided into several virtual compartments, and server software is setup on them separately, making each unit capable of functioning independently and isolated from others.
So web sites hosted  on virtual compartment allocated  with isolated server resources (CPU, RAM, disk space, etc).

On VPS Server You get complete root “Administrative” access to your server as if it were your dedicated server. But technically you are still on the same physical machine and sharing its CPU, RAM, disk storage, and bandwidth.

Now let’s compare VPS server with other hosting technology:

VPS vs Shared Hosting:

Shared Hosting is cheaper than the VPS servers , but
if your web site hosted on shared hosting , your web site resources may affected by others becuase you are sharing the same resource from the physical server like RAM ,Storage space,CPUs , and bandwidth .Unlike VPS Servers all allocated resources are isolated from others but sill on the same physical server ,on VPS server you just get peices of the resources as virtualized server

VPS vs Dedicated Hosting

VPS servers is cheaper than Dedicated Hosting
In dedicated hosting, you have your very own space and are responsible for everything on the property ,
that’s means you own and earn the entire server resources physically and each time you want to change the resources you have to replace it which means the server should be shutdown and process the replacement , unlike the vps servers you can upgrade/downgrade the resource without shutdown the vps server.
