Virtual Private Servers (VPS) Web Hosting Defined |
|
Have you ever wanted to put your website into its own machine but do not need all the power and space of a full dedicated web server? Virtual Private Servers, or VPS, fill that intermediate space. VPS are basically virtual machines, much like one that you might run on your own computer to mimic another PC running within your computer. To the web server and operating system running within the VPS, it appears as though they own the entire computer. Each VPS has a certain amount of disk space, RAM and bandwidth allocated.
Web hosts that provide VPS often give their customers virtually complete control over their VPS, allowing them root access (or administrator's access). You can thus usually install and run any software you want into your VPS, host any number of domains you wish, and so on. You are basically the boss of your own virtual server. |

While Virtual Private Servers have certain benefits over full dedicated web servers, you should note that it usually runs slower with less resources than if you were to have your own real dedicated server. If your website has drastically outgrown shared web hosting, a VPS may not necessarily be the best solution. You may need to go with Dedicated Servers (Web Hosting) instead. 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 super user-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 . |
