A Virtual Private Server (VPS) is an independent server within a server. When a VPS is created, one physical server (master server) is made to host multiple virtual servers. This is done with software (namely, hypervisor) that segments the master server’s hardware specs so that each VPS segment functions separately and independently of one another.
Segmenting a server basically means that each VPS runs its own operating system — one that is independent of the main server, and which can be rebooted at will without affecting any other VPS. It’s primary advantage is in offering hosting at cost-effective rates and with greater freedom of configuring and organizing online servers.
How does a Virtual Private Server (VPS) work?
The functionality of a VPS can be described using four terms: compartmentalization, dedicated resources, root access, and isolated hosting environment.
To create a VPS, the physical server is divided into multiple virtual compartments (virtual CPU specs, RAM, hard disk space, etc). Think of it like segmenting a hard disk into multiple drives. However, with a VPS, compartmentalization goes beyond just allocating hard disk space.
When the server software is set up, each virtual compartment is allotted a specific quota for using the master server’s resources. This includes a dedicated percentage of the server disk space, CPU, and RAM. Hence, when your website is hosted in this new compartment it will operate as if the allocated resources make up the specs for its server. This obviously means that the more compartmentalization’s that exist on a master server, the more powerful hardware it deploys.
When compartmentalization and resource allocation are complete, the VPS behaves like a standalone, dedicated server. Hence, you will gain complete root access to the server (and hence complete control over server), allowing you to configure the VPS system as per your needs. As a result, every single server is allowed to select its very individual operating system, configure existing components, and setup new ones and be able to restart it at anytime.
Compartmentalization creates an isolated environment for your VPS. Whatever changes you make, or configurations you perform on your VPS cannot affect any other VPS on the same system. The same holds true for all other VPS on the master server. Hence, any instances of malware or cyber threats that have affected, or are affecting any VPS on the master server cannot affect your VPS.
Think of it like living in a colony of bunkers, where though each may be sharing the same resource pool, each is self sustaining and completely isolated from neighboring bunkers. Hence, with a VPS, even though all the VPS servers on the master server are sharing the same hardware resources, each will always operate differently from each other. If one server has a problem, it’s there problem alone and none of the other servers will be affected because of it.
