Analysis and Comparison of Distributed Computing Model

Distributed computing is a new technology which has been put forward these years.Aiming at a few of predominant distributed computing technology,like Web Services,Middleware,Grids and so on.This article analyses and compares their characteristics,although each distributed computing technology is different in idea,specification,application and implementation,each technology has been developed and applied in some extent,and each could solve distributed computing problem in specified environment.Therefore,the combination of computing technology have been studied is not only the field of distributed computing in the future,but also playing a key role in development of distributed computing technology.
