Service Mesh Integration & Telemetry

intermediatekubernetesservicemeshdevops

Integrate a service mesh for secure, observable microservice communication

← Back to Intermediate

Learning Objectives

Deploy Istio or Linkerd into your cluster

Enable mutual TLS (mTLS) between services

Configure request routing, retries, and circuit breaking

Collect mesh telemetry and visualize traffic flows

Secure ingress and egress within the mesh

Requirements

  1. Install Istio or Linkerd control plane in your cluster
  2. Inject sidecars into your application Namespaces
  3. Enable mTLS for service-to-service encryption
  4. Define VirtualServices and DestinationRules for canary traffic
  5. Collect and view mesh telemetry (e.g., via Kiali or Grafana dashboards)

Stretch goals

  • Implement advanced traffic shifting (A/B testing)
  • Simulate a service failure and observe circuit breaker behavior
  • Export mesh spans to an external tracing system

Deliverables

  • Mesh installation manifests or Helm values
  • Routing rules and telemetry dashboards screenshots
  • A brief report on security and observability gains

This exercise will demonstrate the power of service meshes in production.
