Linkerd is an ultralight, security-first service mesh for Kubernetes that adds mutual TLS, observability, and reliability features to cluster workloads with no code changes. It consists of a Go-based control plane and CLI plus a Rust-based data plane micro-proxy (linkerd2-proxy), and is a CNCF graduated project.
Use cases
- add mutual TLS to kubernetes services without code changes
- get golden metrics and latency dashboards for microservices
- load balance gRPC traffic in kubernetes
- enforce zero-trust authorization policy between services
- add retries and reliability to service-to-service calls
- debug 502 errors in meshed applications
- choose a lighter service mesh than istio
When to choose
- you run Kubernetes and want a simple, low-overhead service mesh
- you need zero-config mTLS and zero-trust policy
- you want gRPC/HTTP2 load balancing that Kubernetes doesn't provide
- memory-safety and regular security audits are requirements
When to avoid
- you need multi-cluster or VM workloads outside Kubernetes
- you need Envoy's extensibility or a general-purpose proxy
- you want a mesh for non-Kubernetes environments
