Introduction to service mesh with Istio and Kiali
summary
Istio runs Envoy sidecars injected into each pod to control service-to-service traffic and Kiali visualizes and validates that control the demo shows live changes creating virtual service + destination rule objects that immediately shift weighted and canary traffic, and Kiali calculates health from Prometheus metrics and traces. Runtime features include Envoy sidecar proxy routing, mutual TLS via Citadel for service certs, circuit breaking, and chaos tools like traffic mirroring and fault injection the presenter’s Bookinfo demo shifts 75/25 traffic and injects 100% 500 errors for a specific header and the UI reflects errors and traces in real time.
