an alternative to client-server computing. This mode began in the days of the mainframes where the heavy workloads of programs were executed on the central servers. Since computing power was complex, scarce, and expensive the functions were centralized. In this mode network traffic is greatly reduced since only keystrokes, mouse movements, and graphics flow back and forth between servers and clients. This mode of computing allows more efficient management as updates, adjustments, and new applications are installed once and rolled out to users without manually configuring each computer. Businesses can put aside the role of technician and concentrate on the tasks of seliing products and serving customers. Security and reliability are greatly enhanced since the rights to add and adjust software are granted only to the skilled technical administrators (in larger customers), whereas in client-server environments user actions cannot be easily controlled. Performance of older computers is improved since the actual work occurs on powerful servers, which impacts longevity and extends the useful life of these machines. There are many reasons for businesses to utilize this mode of computing. As the Internet and Information portability become more prevalent, centralizing technology so that it can interoperate and be available from anywhere is key to this success. Also, managing the ever-changing architectures and emerging technological standards becomes easier when your infrastructure is centralized and standardized.
