Virtual Dedicated Server (VDS) Technology is a new technology based on the concept of partitions on mainframes and advanced resource scheduling to divide a computer into many virtually isolated servers. A VDS simply put is, a server that runs inside another server. Each VDS acts like a dedicated server but shares the same hardware.

VDS technology completely isolates each VDS, creating a more secure and reliable hosting environment. Each VDS has its own isolated disk space, guaranteed network interface bandwidth, guaranteed cpu allocation, RAM and operating system. If a VDS on the same physical server crashes, the other accounts on the server are protected and remain unaffected. It is not possible for any account to use up all the RAM, disk space, network bandwidth, CPU cycles, or any other resources of the Hosting Server.

The plain and simple is that its a Dedicated server thats been partioned to appear like seperate machines. For example lets say you had a 4 processor machine with 4gigs of ram and 80gigs of disk space. You could have the server setup in such a fasion that you have 4 VDS's on one machine. Each VDS has access to only 1 CPU and only 1 GIG of ram and only 20gigs of disk. If someone really screws up their VDS the other VDS's on that server are unaffected because all four are operating in their own virtual enviorment with their own operating system, hardware, etc. If someone powers off the dedicated server all four VDS's are affected aswell as if there is a harddrive failure all 4 VDS's are affected as the bad disk is replaced.

I've been using a VDS (called VPS by my host) for several months now and I have to say it has performed beautifully, and a damn sight faster than the 2.2ghz dedicated it was on before! I would recommend this to anyone who like me is on a tight budget but needs the power of a dedicated server.
The host I used was beamhost.co.uk
