What Everybody Ought to Know About Virtualisation

Fasthosts offer the UK’s best spec virtual private servers (VPS) which are perfect for high traffic websites and business-critical applications. This is because we have built a platform that is far superior to many of our competitors.

Many people do not realise that not all virtual servers are created equal. There are different types of server architecture and virtualisation which have a dramatic effect on performance.

What’s the difference?

Type 1: High end virtualisation

This is the award winning virtualisation that we have built at Fasthosts. The virtual servers have independent, isolated operating systems and access hardware resources easily through a thin hypervisor.

Type 2: Low end virtualisation

This is the virtualisation that a vast majority of our competitors use. Virtual servers run on top of a virtual machine manager. They share aspects of a host operating system, which they must run through before they access hardware resources.

The Type 2 virtualisation model means that virtual servers are sharing aspects of a host operating system. This results in competing for resources which can impede performance.

Server Architecture


This is the architecture that Fasthosts use. The virtual servers share the resources of several physical servers and a centralised storage. This architecture supports automatic failover and load balancing which gives your VPS better performance and high availability.


In this architecture, virtual servers run on specific physical servers and use direct-attached storage. You won’t get load balancing and automatic failover if you choose a virtual server that operates from standalone architecture.

Our virtual servers are cost-effective, reliable and can scale as your business grows. Click here to check out our VPS range.
