Virtual Dedicated Server (VDS)

A virtual dedicated server (VDS) also called as a virtual private server (VPS). This appears to the user as a dedicated server but is actually installed on a computer serving multiple Web sites. A single computer can have several VDSs, each one withVirtual Dedicated Server VDS its own operating system (OS) that runs the hosting software for a particular user.

The hosting software for each VDS can include a Web server program, a File Transfer Protocol (FTP) program, a mail server program and specialized applications for activities such as e-commerce and blogging.

The VPS alternative is often chosen by small businesses that need a customized Web site but cannot afford a dedicated server. Another useful aspect of VPS technology is the ability of a single subscriber to maintain multiple virtual servers. For example, a Web site owner might use one server for the production-level Web site and the other for a "dummy site" that can be used to test planned updates, modifications or new programs.

Virtual dedicated servers offer many of the capabilities and features of dedicated servers, including admin (root) access and dedicated IP addresses, but at a much lower price. However, as a virtual dedicated server is, indeed, virtually dedicated, the customer, in fact, shares the server space with a small number of other customers. However, because each virtual dedicated server is effectively isolated from other accounts on the server, the user has full control over the server space. As well, virtual dedicated server plans feature very high performance and available disk space and bandwidth.

Virtual dedicated servers enable hosting providers to offer services are based on the concept of partitions on mainframes that allow each division to function as a virtual standalone server dedicated to a single customer.

To ensure high and reliable performance for all accounts, server boxes are partitioned in such a way that each virtual dedicated server operates almost entirely independently of the other accounts that share the server space. This means that with a virtual dedicated server, you will enjoy consistent, high performance, even when usage peaks on the main server.

Virtual dedicated servers are particularly useful for companies and individuals that run higher-traffic Web sites or complex applications and thus need the bandwidth, consistent performance, and flexibility of a virtual dedicated server.
