There has been a lot of talk about virtualization, cloud and utility computing and the increased advantages of thin client or server-based computing. Here we discuss the history, future and benefits of this technology.

In simplest terms, thin client/server-based computing describes a shift away from the complexities of the typical modern personal computer (PC)-based network. While the PC started out as a simple tool which enabled individuals to increase their personal productivity, it has in fact become a rather complicated device. Just when you think you have your PCs working perfectly, new applications, devices, drivers, Internet access, etc., are required, and each PC needs to be individually upgraded, reconfigured, or even completely replaced. As a result, what started as a simple personal computer evolved into a rather complex "fat client" network.

Thin client computing is a response to this constant PC desktop upgrade and maintenance cycle with its high cost and high manpower requirements disrupting the flow of business. A thin client is a "display-only" device, meaning it displays applications that run on dedicated servers rather than on the PC.

Many people can relate this approach to the experience of using an older style "mainframe" terminal. These are very simple devices— plug them in, log on, and start working. No one has ever complained about the reliability, speed, or productivity of using a simple computer terminal. They tend to be extremely reliable and easy to maintain, with a very long operational life. The only drawback has been the lack of a graphical user interface (GUI) and the inability to run popular MS Windows compatible applications. However, new thin client desktops manufactured by world PC leader HP, combined with powerful servers, now have the ability to run MS Windows, MS Office, any application and multimedia graphics. While the mindset is to consider terminal computing old fashioned, this technology is current. As the saying goes – what’s old is new again!
