21 years and counting of 'eight fallacies of distributed computing' (2025)

The article examines the "eight fallacies of distributed computing," a set of long-held incorrect assumptions about networks that originated at Sun Microsystems in the 1990s and remain relevant today. Originally developed by Bill Joy and Tom Lyon (four fallacies), then expanded by L. Peter Deutsch and James Gosling (four additional fallacies), these misconceptions—such as assuming the network is reliable, has zero latency, and is secure—continue to influence how developers, administrators, and users interact with networked systems. The author argues that understanding these fallacies is essential for designing better protocols and software, as they highlight critical questions about data transmission, reliability, and network behavior.
