Foundational
Idempotency is a design property, not a retry settingAny network call can fail after the work was done and before the answer arrived, leaving the caller uncertain whether retrying will duplicate an effect. That fact makes duplicate delivery structural rather than exceptional, and the only durable answer is receivers that tolerate it.⚙️ Infrastructure at Scale

Cascading failure mechanics: how one slow dependency kills healthy servicesOverload spreads through systems by arithmetic, not bad luck: latency multiplies in-flight work, exhausted pools stall every caller, and retries add load exactly when capacity is lowest. Knowing the three mechanisms and the budget that breaks each one turns the resilience chapter of any interview from vocabulary into reasoning.🚨 Debugging ProductionSign in
