Beginner Topic 16 of 51 Distributed Systems & Cloud
Fault Tolerance
Continuing correctly despite component failures.
How it works
Systems survive failures using redundancy, replication, timeouts, retries with backoff and jitter, circuit breakers and graceful degradation; failure assumptions: crash, omission, Byzantine.
Where it is used
Highly available services.
Common pitfall
Naive retries amplify outages.
Where it fits in the course
Fault Tolerance is topic 16 of 51 in Distributed Systems & Cloud, rated Beginner. It follows Caching Layers. The next topic is Replication Strategies.
