Microservices in the Cloud with Kubernetes and Istio
summary
Live demo shows a simple Node app packaged with Docker, pushed to Google Container Registry, and run as three Kubernetes deployments (front, middleware prod+canary, backend) on GKE; Istio auto-injects sidecars, an Ingress Gateway handles traffic, a ServiceEntry opens egress to worldclockapi.com, and routing rules enforce prod-only traffic until a header routes to canary. Retries=3 fix intermittent 500s, Prometheus and Jaeger provide metrics/traces out of the box, and Istio issues certs for mutual TLS between services while proving canary routing works.
