Although is shared web hosting is cheap, but we can not ignore the existence of its limitations. For those users their web sites have a certain number of traffic, or they need to install additional software in order to achieve some special features, they need an advanced web host product, such as an Dedicated Server or a VPS(Virtual Private Server).
Dedicated Servers is a kind of advanced web host products, it contains an independent operating system, with independent IP, it provide users with a more relaxed environment and flexible access to control their server, based on these feathers,it can meet the demand of higher customers. Different from shared web hosting, dedicated server usually has less restrictions, users have permision to deploy all kinds of resources, including hardware ,software, and networks.
However, these facilities also accompanied by a more expensive price, which not only contains a higher hosting cost, but also requires the users with the appropriate technical capabilities, or they should provide the appropriate technical services personnel. Of course, many hosting companies provide these necessary services, as long as users are willing to pay the price for them.
