How rate limiting, backpressure, and load shedding keep microservices inside safe capacity, with failure timelines, admission controls, and rollout steps.- Published on
How the circuit breaker pattern protects microservices from cascading failures: states, slow-call thresholds, fallbacks, retry interaction, and metrics.- Published on
Why request timeouts limit waiting but cannot stop cascading failures without admission control, bounded queues, backpressure, and load shedding.- Published on
Why retry logic can amplify degraded systems, how retry budgets and jitter reduce retry storms, and what to check before retrying production requests.
