Gathering data about a particular topic, getting in touch with old friends, contacting emergency services, sending large files to a country far away, booking flights, trains etc. The all-pervasive power of the internet at the outset of this technological revolution has the whole world hooked to it.
Websites are the most important mediums to get access to different kinds of information and services. Companies, businesses, individual users these days can not imagine to work without having their own websites. These are uploaded in the internet on spaces called web servers by web hosting processes. The web hosts are companies who own and provide these spaces to upload them on the server. Amongst different types of hosting services like shared web hosting, dedicated hosting services, VPS hosting services etc, the latter, also known as Virtual Private Server, is one with features similar to both shared and dedicated hosting. It is basically one big server partitioned into several small virtual servers possessing their own operating systems. One can operate on the hosting accounts separately; they can be booted and rebooted with its users having full root accesses to the partitions owned by them. Any type of system software can be installed; any root user operation can be executed without disturbing the activities of other users sharing the other partitions on the same server.
This type of hosting ensures that owners of websites get excellent technical control and flexibility to install important system software; advantage is that it is not otherwise allowed in shared hosting. Also sometimes getting the hosting provider to do server management tasks like installing some software or debugging etc comes expensive. In VPS hosting, the users have complete control over their servers with root passwords known to them. The hosting rates also are between shared and restricted hosting services since the service has been in demand for quite some time amidst small to medium scale business.
