Virtual private server (vps) is a term used by web hosting service providers to refer to a virtual machine to be used solely by an individual or a company. A Virtual Private Server accentuate that the virtual server, though operational in software environment on a physical server at different nodes, is functionally equal to any other separate physical computer.
The technical specifications of Virtual Private server can be configured as per the custom requirements of user or a company. Configured with in software environments of a Physical Server Rack, every vps operates through its own full-fledged OS template and can be independently rebooted using dedicated control panel that is usually offered as default with vps hosting products. The practice of partitioning a single server to facilitate its usage as various servers has long been general practice on mainframe CPU and mid-range CPU. The trend of virtual Private Server hosting is getting more popular and easy to handle, with the development of virtual software and technologies for small servers.
The main physical server characteristically runs a hypervisor which is configured to create, wipe out, and manage the resources used by “guest” operating systems, or virtual machines. These guest OS systems are allocated with a share of physical server’s resources.
In a fully virtualized server hosting environment, the guest is presented with an emulated or virtualized set of hardware and is unaware that this hardware is not strictly physical. The hypervisor in this case must translate, map, and convert requests from the guest system into the appropriate resource requests on the host, resulting in significant overhead. Almost all systems can be virtualized using this method, as it requires no modification of the operating system, however a CPU supporting virtualization is required for most hypervisors that provides full virtual server hosting environment. Some examples of virtual server environment proficient hypervisors are Xen, Virtuozzo, Vserver, and OpenVZ and the common features among all control panels are reboot, on/off, 1 click OS template install/update, c Panel install/update.
As of these days, a mass number of web hosting companies like Host Monsterz, Host Gator, Go Daddy has started to offer virtual private server web hosting commonly known as VPS hosting, or virtual dedicated server hosting as an extension for web hosting services for which several licenses has to be acquired from third-party vendors to run and operate their scripts/software on a VPS.
