Linkerd
Linkerd is a CNCF graduated project licensed under Apache v2. Buoyant (https://buoyant.io/) is the major contributor to Linkerd. Out of all Service Mesh technologies, Linkerd is probably one of the earliest, if not the oldest. It was initially made public in 2017 by Buoyant. It had initial success, but then it was criticized for being very resource hungry. The proxy used in Linkerd was written using the Scala and Java networking ecosystem, which uses the Java Virtual Machine (JVM) at runtime, causing significant resource consumption. In 2018, Buoyant released a new version of Linkerd called Conduit. Conduit was later renamed Linkerd v2. The Linkerd v2 data plane is made up of Linkerd2-proxy, which is written in Rust and has a small resource consumption footprint. Linkerd2- proxy is purpose built for proxying as a sidecar in Kubernetes Pods. While Linkerd2-proxy is written in Rust, the Linkerd control plane is developed in Golang.
