Virtual Private Servers (VPS) Solutions
A virtual private server allows multiple customers to share the expense of hardware and network connections, without sacrificing privacy, performance or preference. For this reason, VPS is considered one of the most sophisticated modes of automation available for provisioning small to mid-sized enterprise Web hosting.
A virtual private server eliminates the restrictions of virtual hosting by providing all of the administrative features of a dedicated server. Each VPS user therefore receives their own set of services that they can customise to their specific needs. Virtual hosting is limited in comparison because its users do not have root access and software configurations cannot be customized, despite the fact that physical resources are also multiplexed. A virtual private server on the other hand, contains its own unique file system and CGI-BIN, disk space, system resources, bandwidth and memory allotments, which allow for a high level of customization.
Indeed, many virtual private servers on the Unix platform have become so advanced that they even permit users to install Linux RPM packages. This allows users to take source code for new software and package it into source and binary form, such that binaries can be easily installed and tracked, and source can be easily rebuilt. The use of RPM packages also allows VPS users to maintain a database of all packages and their files that can be used for verifying packages and querying for information about files and/or packages.
Small businesses that run their own e-commerce Web sites also appreciate the functional isolation of their private server, because it allows them to obtain their own secure certificates and shopping cart software for their e-business operations. Indeed, many sophisticated VPS solutions will even offer third-party plug-ins or modules, allowing users to take advantage of control panel functionality in order to install everything from the simplest CGI scripts to the most advanced shopping carts.
