Many web sites are run on shared servers, where the number of sites hosted on a single server could run into the hundreds. Until recently, the next step up for a web site that had outgrown a shared server was to move to a dedicated server, which would host just that one site. Nowadays though, there is another choice – the virtual dedicated server. This is a server that has been partitioned into segments, each of which acts as a dedicated server. On a server of this type, there would be just a few web sites, with the effect that more of the servers’ resources would be available for each web site. As an example, a server may be portioned into 5 virtual servers. This would mean that each virtual server would have the use of 20% of the servers’ resources – processor time, hard disk space and so on. |
