Istio Has a Free API — Service Mesh for Kubernetes Made Easy

Istio is the most popular service mesh for Kubernetes. It handles traffic management, security, and observability between your microservices — without changing application code. What Is Istio? Istio injects sidecar proxies (Envoy) alongside your pods. These proxies handle mTLS, load balancing, retries, circuit breaking, and telemetry automatically. Key features (all free): Mutual TLS between all services Traffic splitting (canary deployments) Rate limiting and circuit breaking Distributed tracing (Jaeger/Zipkin) Metrics (Prometheus/Grafana) Install Istio curl -L https://istio.io/downloadIstio | sh - cd istio- * export PATH = $PWD /bin: $PATH istioctl install --set profile = demo kubectl label namespace default istio-injection = enabled Traffic Management API # Canary deployment: 90% v1, 10% v2 apiVersion : networking.istio.io/v1beta1 kind : VirtualService metadata : name : my-service spec : hosts : - my-service http : - route : - destination : host : my-service subset : v1 weight : 90
