A virtual private server (vps) is a system in which a business or a customer can host their website and make it available online. It is a hosting system that was made for small to medium businesses, as well as individuals who want to have the freedom in configuring their online servers. There are a lot available so there is a wide price range for people to choose from. So basically, it is an independent or separate server, inside a bigger server.
A VPS is considered as a server that is divided into smaller servers that can operate independently and on their own. Each smaller server or each component can create, set and configure things without affecting anyone else in the other smaller servers. It can run it’s own operating system, configure unique settings, and reset and reboot without disturbing the other smaller servers. The main server is an actual, physical hardware that the host company has. That piece of hardware is divided into smaller components which are then rented out to individuals or businesses for their hosting needs and requirements.
It works in a similar way to apartment units. All the units are in one building, but each unit can do its own thing without having to disrupt the other units. One unit can choose to paint their walls blue but the other units don’t have to. When each individual server makes changes or takes action, it also doesn’t affect the main server as well. So one problem with one server will not cause the entire main server to breakdown.
There are 4 main components of a virtual private server (VPS) which is compartmentalization, root access, dedicated resources and isolated hosting. Each of these components/terms/aspects work together to create a server that is more cost effective for businesses or individuals to use.
