mTLS in Istio is configured through PeerAuthentication policies that enforce mutual TLS at the mesh level. Create a PeerAuthentication resource specifying the mode (STRICT for all traffic encrypted) and apply it to your namespace or entire mesh to secure service-to-service communication automatically.

Canary deployments use VirtualService and DestinationRule resources to split traffic between service versions. Define weights in VirtualService to route a percentage of traffic to the canary version, monitor metrics, then gradually increase traffic as confidence grows.

Yes. Service meshes like Istio provide built-in observability through metrics, distributed tracing, and logging. Traffic routing policies automatically generate telemetry that integrates with monitoring tools to track latency, error rates, and service dependencies without application code changes.

Istio supports both through DestinationRule configurations. Circuit breakers detect failing endpoints and stop sending traffic temporarily; retries automatically resend failed requests. Together they improve resilience for microservices communication.

AuthorizationPolicy resources in Istio define which services can communicate with others based on source, destination, and operation. Create policies specifying allowed traffic rules; deny policies block traffic by default, then whitelist permitted routes.

Before deployment, ensure cluster networking is configured, install IstioOperator or equivalent mesh control plane, inject sidecar proxies into workloads, and establish baseline observability. Test mTLS and traffic routing policies in a staging environment first.
