Reliability & Resilience
Every system fails eventually. The question is whether the failure is contained or catastrophic. This pillar covers the patterns that separate systems that recover from those that cascade.

Failure Modes in Distributed Systems
How systems fail — and why understanding failure modes is the first step.
Coming soonTimeouts & Failure Detection
Setting timeouts that actually protect your system instead of hiding problems.
Coming soonRetries and Backoff
Idempotency, exponential backoff, and jitter patterns.
Coming soonCircuit Breaker
Preventing cascading failures by stopping calls to a struggling dependency.
Coming soonGraceful Degradation
Serving a reduced but functional experience when parts of the system are down.
Coming soonMulti-Region Failover
Active-active vs active-passive and the real cost of each.
Coming soonObservability
Logs, metrics, traces — and how to make them actionable.
Coming soonChaos Engineering
Testing failure before failure tests you.
Coming soonBulkheading (Isolation of Failures)
Containing blast radius so one failing component does not sink the whole ship.
Coming soonIdempotency & Safe Retries
Designing operations that are safe to repeat without unintended side effects.
Coming soonRedundancy & Replication for Resilience
How redundancy is structured and why more copies do not always mean more safety.
Coming soonDisaster Recovery Strategies
RPO, RTO, and what a real DR plan looks like under pressure.
Coming soonSLIs, SLOs, and Error Budgets
How reliability is measured — and how error budgets change the conversation.
Coming soonAlerting & Incident Response
Alerts that wake you up for the right reasons, and a response process that works.
