Domain/OS was a distributed, multiuser operating system developed by Apollo Computer and later maintained by Hewlett-Packard after Apollo's acquisition in 1989. Initially introduced as AEGIS in 1981, it pioneered the concept of network-centric computing, where every machine was integrated into a unified network file and user system. In 1988, Apollo added compatibility layers for System V and BSD Unix, renaming the system to Domain/OS.
Hewlett-Packard supported the operating system for a short time but later discontinued it in favor of HP-UX. Final official support for Domain/OS ended on January 1, 2001.
