Battle of the Circuit Breakers: Hystrix vs. Istio
summary
Compares Istio (Envoy-based service mesh) and Hystrix (Netflix Java circuit breaker) by showing what each actually does: Istio implements circuit-breaking at the mesh level with destination rules and a consecutive error threshold sliding window but returns errors with no application fallback, while Hystrix wraps calls in a command, supports fall back to cache and a live dashboard and opens circuits after configurable queues fill. Demo builds an e‑commerce pricing service that fails ~1 in 5 calls; Hystrix opens, serves cached results, retries and closes successfully.
