Distributed operating-system principles

The central question

What changes when cooperating processes run on different machines?

First half

Messages and RPC, latency, timeouts and partial failure.

Second half

Ordering and coordination; replication and consistency fundamentals; a distributed-storage example and paper-analysis preparation.

What you should be able to do

• Explain why a timeout does not establish that a remote operation failed.
• Discuss basic coordination, replication and consistency trade-offs.

A concrete example

Consider two machines, a delayed reply and a retry: distinguish failure from an operation that has not yet answered.
