Virtualization is the most advance form of technology. The implementation of any system in reality is quite tiresome, expensive and the error rate is high but anything is possible without physical labor and money if it could be implement virtually. Same goes for the virtualization of computer server. A computer server consists of several computer linked with it and date sharing is possible between the connected computers via server. In case of web hosting if the server is partitioned into multiple units where the mother server works as an intermediate between unit servers; such method of web hosting is known as virtual server or virtual private server (VPS) According to the user's requirement, many kind of virtual server hosting is available based on currently available computer operating system (Linux virtual servers, Windows virtual servers are example). Virtual servers have a number of benefits. Money is the prime factor for anything and this is true for establishing a server. Several devices, network cable, infrastructure etc are needed to install a physical computer server. In present days it is not possible to found a server that is not multicored and the market price for a multicore server is quite high. A company might not want to buy such powerful machine since their business doesn't require that much but still have to buy them. As a result they have to bear the cost though that give them extra advantage. Several numbers of physical servers is not needed to establish a virtual server. So this is the perfectly economical solution for anyone who doesn't want to bear the cost of installing a physical server. Not ever company is satisfied with shared servers and need to establish a dedicated one. Despite having the requirement to install a dedicated server there is no need to bear the cost of installing a physical one. Because virtual server is capable of providing same access to the user as a physical dedicated server does. Users enjoy the authorization for root access and control for installing their own application. virtual server allow its user to ensure his/her privacy and they enjoy the complete access to preserve their own dedicated system files which is fully secured from the violation of others. If you have hosted more than one server and one of your those database is corrupted, you could revive it or take any steps while not affecting the other databases though they are existing in same server. In case of physical server experiment is quite risky since it could damage the entire server and causes a great financial loss. But in case of virtual server you are free to experiment anything by taking the advantage of virtualization. This is possible for a marvelous feature (named virtual server snapshot) of virtual server which allows user to create recovery points and restore to the previous condition by using the point. This feature of virtual server helps as well by restoring default setting as when software update causes unintended situations.
