How does a Virtual Private Server Work (VPS)?

Virtual Private Servers

Virtual Private Servers (VPS) technology allows you to share server costs with other users, but gives you total control over your own applications. Virtual Private Servers run as isolated processes within a Web Server, and provide root access in complete privacy with the ability for guaranteed bandwidth, CPU, and disk space.

A SmartServers Virtual Private Server (VPS) from VirtualServers.com is the most innovative, complete and fully-featured Virtual Server available anywhere on the Internet. Unlike other providers who offer you low-grade virtual hosts or "virtual servers" which have only limited features and capabilities our servers give you access to the complete range of virtual services including FULL ROOT ACCESS to a complete FreeBSD server system with your own dedicated telnet, web, ftp and email servers, full access to all server configuration files, support for unlimited virtual hosts/domains, unlimited POP/FTP/TELNET/SSH accounts, and even your own Virtual DNS Servers (NS1&NS2.yourdomain.com).

SmartServers is one of only a few providers who are able to offer genuine Virtual Private Server systems as most other providers do not have the technical expertise or resources to develop and maintain their own systems of this type and as a result have to resort to offering inferior configurations via the use of one of the various available "control panel" software packages such as "Plesk" or "Cpanel".

Each virtual private server looks and behaves exactly like a real dedicated server system, complete with your own set of unix init scripts, user logins, system processes, file-systems with unlimited root access, and custom application software such as the apache web server. VPS servers provide the highest level of security just like a dedicated server, complete with customizable firewall proteation and secure isolated disk space.

A virtual private server is a method of partitioning a physical server computer into multiple servers such that each has the appearance and capabilities of running on its own dedicated machine. Each virtual server can run its own full-fledged operating system, and each server can be independently rebooted

The practice of partitioning a single server so that it appears as multiple servers has long been common practice in mainframe computers, but has seen a resurgence lately with the development of virtualization software and technologies for other architectures.

Virtual Private Servers (VPS) are designed for the customer looking for more control than a shared web hosting account, yet not ready for a dedicated server. These private servers include root access, guaranteed resources, a full-featured control panel, and complete web hosting technical support. Other services such as web design and Ecommerce are also available.

Uses of Virtual Private Servers

Virtual private servers bridge the gap between shared web hosting services and dedicated hosting services, giving independence from other customers of the VPS service in software terms but at less cost than a physical dedicated server. As a VPS runs its own copy of its operating system, customers have superuser-level access to that operating system instance, and can install almost any software that runs on the OS. Certain software does not run well in a virtualized environment, including firewalls, anti-virus clients, and indeed virtualizers themselves; some VPS providers place further restrictions, but they are generally lax compared to those in shared hosting environments. Due to the number of virtualization clients typically running on a single machine, a VPS generally has limited processor time, RAM and disk space.

Due to their isolated nature, VPSes have become common sandboxex for possibly-insecure public services or update testing. For example, a single physical server might have two virtual private servers running: one hosting the production-level (live) website, and a second which houses a copy of it. When updates to crucial parts of software need to be made, they can be tested in the second VPS, allowing for detailed testing to be conducted without requiring several physical servers.
