Dedicated Server vs VPS
Virtual Private Servers (VPS) offer a pseudo-dedicated solution that is typically sought after for development and isolation of smaller domains. We say “pseudo” because it is not a dedicated solution, but attempts to imitate one in a virtual environment. This solution is typically used for low resource usage sites that have special needs, as opposed to an actual dedicated server that is often acquired for high usage needs. Often times clients have the misconception that a VPS will provide similar options to a dedicated server, but this is not the case. With a VPS you have your domain placed on a server, which has multiple VPS clients on the server. This often times causes the VPS to function more similar to a shared account than a dedicated account and tends to face similar issues with resource constraints that are faced in a shared environment. A VPS offers more options than a shared server, such as allowing some more freedom with software installs, coding and scripts. The only problem is that a VPS is still limited by its own virtualization. In other words, certain software does not run well in a virtualized environment, including firewalls, anti-virus clients, and indeed virtualizers themselves.
A Dedicated Server is a machine that is allocated to one and only one client. You may have as many customers on your server as you would like. It provides for complete control of your hosting solution, including benefits that the VPS does not offer. You may install any program that you desire and update programs anytime. Dedicated solutions are often times offered to clients that need room for uninhibited growth, that need a solution for intensive websites (many visitors and high resource usage), and for clients that have outgrown a VPS.
To sum it up, you need a dedicated server if :
.:Your site gets so many hits that your Virtual Server account cannot handle it.
.:You want to host many sites on the one server.
.:You need a feature that is not offered on a Virtual Server.
.:You require a high level of security.
.:You would like full control of software installations
Aside from these performance issues the other difference is price, which can be checked at the following two links.
