For people with clients, such as Graphic Designers and Web Designers a dedicated server is invaluable. A dedicated server will bring extra income into the studio, not just as a hosting facility, but, as a designer knows only too well, for the extra 'bread and butter' income value. If you have 24hour access to your own dedicated server then you can adjust, correct or update a clients website in minutes, allowing you to keep the dollar back in your studio and not in someone else's. Ready availability results in reduced labor costs for the client, but higher studio-income frequency for the designer. Hence you will see the return of all your regular offline clients, bringing their web work with them.
Hosting your web sites on your own dedicated server may seem a little expensive in comparison to shared web hosting, but the end result is more advantageous. Shared web hosting, no matter how well managed, cannot be 100% reliable and stable. However if you have your own dedicated server you can manage to avoid most of the variables affecting the reliability and stability of a server, commonly experienced by shared hosting accounts; variables such as: overload, bad codes and scripts from other users (especially beginners); and, too many applications and components uploaded, and so on.
A dedicated server reduces your dependency on the web host; and bypasses time delays and possible expenses incurred from these. With dedicated server hosting you can provide instant support to your own clients whenever required, which is not possible if you are on a shared server.
Not only for Web designers but if your business website is quickly downloadable and up all the time gives the visitor encouragement that your service is just as reliable, hence you will be more likely to make a sale. It will also enhance the company's image and encourage existing customers to refer your service to others. This will result in more sales for less promotion.
