Virtual server in basic terms is a device or server that runs and modulates the functioning various operating systems, server soft wares and configurations; while at all times being linked to the same hardware. These servers find users in high traffic websites that are in need of efficient web hosting services, and are the perfect solutions to a low cost, efficient web hosting. Users can choose between virtual private servers or more advanced virtual dedicated servers depending on their usage. Principle behind Virtual Hosting The overall phenomenon that this form of web hosting works on is called as virtualization. Virtualization allows a single hardware/ computer to operate multiple operating systems simultaneously. It is the solution to meeting increasing demands for more and more web space and the need to run more applications. A virtual server in itself is not real, i.e., it lacks its own hardware. For memory and hard disk space, a virtual server is linked to a host which is further common to many other similar servers. However each operating system is independent of the other; each has to be rebooted separately. As an example, a typical host server with a disk space and memory runs an operating system. This host caters to many 'guest' servers- servers that run their own operating systems but depend on host for hardware. This is a form of partitioning where virtual web servers utilize virtual processors. Why Choose Virtual Server for Your Website Internet has become the fastest and easiest way for people to browse for services, and for companies to extend their services. With new websites being added every moment, web space required by websites to expand will become a limiting factor. For this reason, businesses go in for virtual server program. Opting for virtual web servers instead of the traditional shared hosting services offers some advantages: 1Virtual web servers allow users to draw maximum output from a single server and yet be able to maintain multiple websites. For this purpose, a virtual server works with a single operating system and a single server. 2Traditional web hosts do not provide much flexibility over the functional control of the web site they host. However, a virtual web server gives more control to the user when dealing with the configuration of their web sites. Also, different web sites can be configured individually. 3The users have a substantial control over the working of their web site. 4The individual web sites hosted by a single server are completely independent of each other. Each can be customized with its own applications and soft ware, without interfering with the other site. 5Many servers provide features such as unlimited email addresses, anti-virus protection, and spam filters. Large businesses with more focused needs for their websites can opt for even more personalized web servers. These are the virtual dedicated servers. These servers direct all their resources towards a single web site. The sites requiring such servers are those that deal with heavy web traffic, and have special soft ware needs.
