Linkerd Service Mesh Deployed on AKS to Boost Security and Observability

A technical implementation of Linkerd, a lightweight Rust-based service mesh, was carried out on an Azure Kubernetes Service cluster to address the growing complexity of microservices communication. The deployment enabled mutual TLS encryption, real-time traffic visibility, and reduced operational overhead across services. Linkerd's architecture relies on a Control Plane for policy and identity management and a Data Plane of sidecar proxies injected into application pods. Post-deployment testing confirmed successful proxy injection, stable control plane components, and accessible observability dashboards. Key takeaways include the importance of namespace planning, GitOps-based automation, and proactive certificate monitoring for production readiness.
