21 years and counting of eight fallacies of distributed computing | APNIC Blog

▤ Summary

This article explains the eight fallacies of distributed computing and why they still matter for networked software. It walks through each fallacy, covering reliability, latency, bandwidth, security, topology changes, administration, transport cost, and homogeneity. The piece ties these ideas to practical concerns such as TCP, QUIC, TLS, BGP, CDN behavior, and home network performance. It also argues that developers and operators should design for network failures and shifting conditions instead of assuming ideal behavior. Overall, it serves as an educational guide for people building or operating software that depends on networks.
