Why Linkerd?

reliable

Reliability

Your customers rely on you. Linkerd adds critical reliability features like retries, timeouts, traffic splitting, and more to almost any Kubernetes application, improving reliability without code changes.

secure

Security

Zero-trust security isn't just a nice idea, it's the best practice for cloud native environments. Linkerd adds mutual TLS (mTLS) between services, transparently encrypting and authenticating connections without developer involvement.

observability

Observability

You can’t change what you can’t measure. Linkerd's powerful metrics, tracing, and request inspection features allow you to gain vital insights into the behavior and health of your Kubernetes application, without any modifications.

What is Linkerd?

Linkerd addresses a core challenge faced by engineers building modern "cloud native" applications today: adding and maintaining critical security, reliability, and observability features to their microservices applications without changing any code. It's lightweight, secure, and fast to implement. Give it a try!
