Introduction

Distributed systems

• Distributed systems = Computers + relativity
• Different machines have different clocks, perception of time, and views of the state of the system
• Challenges: Communication failures, hardware failures, latency, bandwidth
• All computer systems today are distributed at some level (nature obeys relativity after all), the extent to which this nature is exposed depends on the loads put upon the system.
