Dedicated Server
For sites requiring more power than what normal hosting can provide, a dedicated server is usually the better route to take.
Having a dedicated server is a completely different from normal virtual (shared) hosting. The server is now fully yours – the entire hard disk and all the bandwidth allocated can be used as you want. There is no longer any CPU Usage restriction. If you need, you can use up 100% CPU utilization. You can put all your sites on this one server without having to worry about paying hosting fees for each site added.
Dedicated servers come either as just plain installations (where only the operating system and basic services are installed) or with a control panel. The control panel lets you easily modify most server features from a web page. It should be noted that the control panel will have limitations, and will not provide access to everything.
It should be noted that with a dedicated server, even though you may be paying a set up fee, the server is usually owned by the company . you are only renting it for the time being.
