Linkerd Service Mesh

Linkerd is a CNCF-graduated service mesh for Kubernetes that transparently adds mutual TLS encryption, latency-aware load balancing, retries, timeouts, circuit breaking, and observability to any Kubernetes workload without code changes. Supports HTTP, HTTP/2, gRPC, and TCP traffic.
