Virtual Server PDF Print

The term “Virtual Server” stands somewhere between the terms “Shared Hosting” and “Dedicated Hosting”.

At building such Server, a Physical Server is divided in several separate Virtual Servers. Considered on its own, any of these Virtual Servers could be seen as “dedicated”, as a separate Operating System will be installed on it according to the clients' needs, and this system will support only Applications of a separate client.

Usually the Software used for “visualization” of the Server is VMware, FreeVPS, User-mode Linux, OpenVZ, FreeBSD JAIL, etc.

The Server's settings are optimized for the work of the respective Application as much as possible, while the resources it could dispose of are much more than the onces provided when a Shared Hosting is used. Virtual Server is recommended for Websites and Applications which require specific settings of the Operating System or which generate heavy server loads.

Building of a Virtual Server will drastically cut the expenses for a communication equipment. It will only be necessary to buy one Physical Server with utmost hardware resources.

The following step is installation of the Operating System whereupon the Virtualization Software will be built, as well as determining the number of the Virtual Servers to be implemented on the real one.

When using Virtual Servers you practically divide on one physical machine all the services you use. It is thus possible to allocate the necessary CPU time and other resources for the Virtual Servers installed on the Physical one. In this way neither of the Virtual Server's services could be overloaded, if another service tries to occupy more real memory, hard disc and CPU time resources of the physical machine.

The Virtual Server has many advantages but it is however not always a good idea to start on it the whole company's infrastructure.
