Editor's Notes

  1. The fallacies of distributed computing describe common assumptions that are made by developers and architects in distributed systems. In 1994 Peter Deutsch wrote down seven fallacies. In 1997 James Gosling added another fallacy. These fallacies are known as “The eight fallacies of distributed computing”. In the year 2006 Ted Neward added three more fallacies, which are not so widely known. The system is atomic/monolithic. (Ted Neward) The system is finished. (Ted Neward) Business logic can and should be centralized. (Ted Neward)
