Virtual Hosting the perfect option to sites that have outgrown shared hosting.
When a host computer runs multiple web servers simultaneously it is known as virtual hosting. This system relies on virtual DNS resolution which permits specific domain names to be assigned to each web server. So, a single computer can then host many independent web sites. Virtual web hosting is either name based or IP based and allows a great degree of manageability, efficiency, and scalability of the infrastructure.
When a web site has outgrown in many ways its hosting solution then the most workable option is virtual web hosting. This is cost efficient as compared to setting up your own dedicated server.
In virtual hosting, resources are not shared with other web sites. Each website is assigned fixed amounts of available resources. So, a single site cannot utilize disproportionately all the resources.
Each website has its own operating system on the virtual hosting server with an isolated segment of disk space and in some cases specific hard drives on the server. So, crashes or technical problems encountered by other sites on the host server will not affect your site....
