Module 7
Fault Tolerance & Reliability Engineering
1
Classifying Distributed System Failures
Classify failure modes in distributed systems: crash, omission, Byzantine, and gray failures.
2
Failure Detection Mechanisms and Trade-offs
Analyze failure detection mechanisms and their trade-offs, including heartbeats and phi accrual detectors.
3
Cascading Failures in Distributed Systems
Analyze the mechanisms and common patterns of cascading failures in distributed systems.
4
Resilient Inter-Service Communication Patterns
Design retry, exponential backoff, and circuit breaker strategies for inter-service communication.
5
Designing Resilient Systems
Design cascading failure mitigation strategies, including bulkheading and adaptive rate limiting.
6
Graceful Degradation Patterns
Explain graceful degradation patterns, including load shedding and priority-based serving.
7
Multi-Region Deployment Topologies Compared
Compare active-active, active-passive, and active-standby multi-region deployment topologies.
Multi-Region Failover Strategies
Design a multi-region failover strategy, including health checks, traffic routing, and data replication considerations.
