What is OSI Monarch?

OSI Monarch was an ambitious, but ultimately unsuccessful, distributed operating system project from the Open Software Foundation (OSF) in the early 1990s. The goal was to create a highly scalable and fault-tolerant operating system that could run across a cluster of machines, providing a single-system image to applications. It aimed to provide features like distributed file systems, distributed process management, and advanced security. However, the project faced significant technical challenges and was eventually abandoned due to its complexity and the emergence of alternative technologies and standards such as the Internet and client-server architectures.
