Virtual private server is nothing but a marketing term used by Internet Hosting Services which refers to a virtual machine for the use of an individual customer availing the service. Even software running on the same computer as same as the individual customer computer, it absolutely work as a separate computer and for the need of the customer. It also has the privacy of the separate physical computer and can run just like a server computer if configured. The term VDS is less used for the same process compared to VPS, each of these can run their own operating system and can be independently rebooted, which helps the user a lot in configuring any process and using it. Partitioning of a single server is done so that it can be showed as multiple has been in practice since a long time, especially both on mainframe computer and mid range computers. It has become more popular with the development occurring day by day in case of virtualization of software and technologies for micro computers.
It bridges the gap between dedicated hosting services and shared web hosting services by giving independence of the VPS services in software terms. It cost less compared to physical dedicated servers. It runs at its own operating system and is capable of running any software on other operating systems some doesnt run in virtualized ones. There are two types of hosting, the first one is Unmanaged and other is unmetered. In the case of unmanaged one the customer is left to monitor and administer their own server and in the case of unmetered one, unlimited amount of data transfer is allowed on a fixed bandwidth line. Unmetered hosting is offered with 10 Mbit/s, 100 Mbit/s or 1000 Mbit/s.
Here the customer can use 3.33~ TB on 10 Mbit/s, 33~ TB on 100 Mbit/s and 333~ TB on a 1000 Mbit/s line. A VPS is also referred as cloud server it has two attributes which are- additional hardware resources can be added at runtime (CPU, RAM), and Server can be moved to other hardware while the server is running (automatically according to load in some cases). As an intermediary service between shared web hosting and dedicated server hosting, the actual hardware server is divided into several isolated environments. Each environment, or space of the hardware, has its own server software, mail server, and independent software instances and services. VPS hosting offers an extremely affordable hosting solution for business owners.
