Istio Has a Free API: Service Mesh for Kubernetes Microservices

Istio is an open-source service mesh that provides traffic management, security, and observability for microservices. It transparently layers onto existing distributed applications without changing code. What Is Istio? Istio is a CNCF graduated project that adds a proxy sidecar to every pod in your Kubernetes cluster. These proxies handle all network traffic, providing mutual TLS, traffic routing, circuit breaking, and detailed telemetry automatically. Key Features: Automatic mutual TLS encryption Traffic routing and splitting Circuit breaking and fault injection Rate limiting Distributed tracing (Jaeger, Zipkin) Metrics (Prometheus + Grafana) Access logging Authorization policies Installation # Install istioctl curl -L https://istio.io/downloadIstio | sh - export PATH = $PWD /istio- * /bin: $PATH # Install Istio with demo profile istioctl install --set profile = demo -y # Enable sidecar injection for namespace kubectl label namespace default istio-injection = enabled # Verify istioctl
