Before virtual servers, customers had a choice of shared hosting or dedicated hosting. Shared hosting is limited, and your stuck with a preconfigured system trying to fit every customer need. Dedicated servers give the ability to customize the server for your own use and provide additional security over shared hosting. However, Dedicated Servers are expensive. This is where Virtual Servers come in, virtual servers give you the additional customization and added security of a dedicated server while being reasonably priced!
