Linkerd is a lightweight service mesh that provides observability, reliability, and security for Kubernetes applications. One of its powerful features is automatic protocol detection, which allows Linkerd to identify the protocol being used by incoming connections without requiring explicit configuration.
This automatic detection enables Linkerd to apply protocol-specific features like HTTP metrics, retries, and load balancing strategies without manual annotation of every service.
