What is a Virtual Private Server?

A virtual private server (VPS) is a server that is virtual rather than physical. Think of it like a digital server that has no physical components.

These are then kept on a physical server. The biggest benefit is that multiple virtual servers can be kept on one physical server. This means you can save on physical space and money as they cost much less! These work almost the same as a regular server.

Of course, you’re limited to the total amount of physical resources available. You can’t magically create hardware!


A Cheaper Alternative

Virtualisation was invented by companies that were trying to be more efficient with resources. Because it was common for servers to have spare resources for busy periods and maybe future growth.

However, because of this, servers could only be using 10-20% of their resources.

To combat this, virtual servers were created.

Multiple servers could be kept on a single physical hardware server. This resulted in servers being able to use up to 80% of their physical resources. And this is much more cost-effective and efficient.

Think if you had the option to choose between 5 Virtual Servers or 5 physical servers (which won’t get fully utilised). Which do you think is the best value for money? We’ll give you a clue – it’s not physical servers 😉

Physical servers were like driving an empty bus around. Whereas virtualisation is more driving like a bus full of passengers. It utilises more of the potential.

why drive around an empty bus?

How Virtual Servers Work

Virtual servers work by using Hypervisor, something that acts as a translator between the physical hardware and the virtual ‘hardware’. Each virtual server only needs to talk to the hypervisor (not the hundreds of types of hardware). This means that the Virtual Servers are portable between physical servers.

A VM is saved as a couple of files, therefore making file management easier! One is saved as a configuration file and the other which is the whole server and its data.

Why Use a VPS?

The main benefits of using a VPS are:

  • Much lower cost than a physical server
  • Almost instant to set up
  • The flexibility of resources to scale to your growth
  • Some practical uses as a physical server
  • Convenience as a VPS can be moved around easily
