This week’s highlighted open-source project, Linkerd is a service mesh for Kubernetes and other frameworks. It offers runtime debugging, observability, reliability and security without requiring changes to code.

Linkerd works by installing a set of ultralight, transparent proxies next to each service instance. The transparent proxies act as highly instrumented out-of-process network stacks, sending telemetry to, and receiving control signals from the control plane. The proxies are written in Rust.

Linkerd is fully open source, licensed under Apache v2, and is a Cloud Native Computing Foundation incubating project as of early this year. Linkerd is developed in the open in the Linkerd GitHub repo.
