Why install Linkerd?

Reliability

Your users are relying on you. Linkerd adds critical reliability features like retries, timeouts, traffic splitting, and other to almost any Kubernetes application, improving site reliability with no code changes required.

Security

Zero-trust security isn't just a nice idea, it's the best practice for cloud native environments. Linkerd transparently adds mutual TLS (mTLS) between services, adding transport encryption and authentication without the mess.

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..
