f/toc/pull/25Please vote +1/0/-1---Name of project: linkerd
Description: Linkerd is an open source service mesh for cloud-native applications. It is a layer 5/7 proxy that provides fully decentralized request-level reliability and optimization to service communication, including latency-aware load balancing, retries, failure handling, circuit breaking, and deadlines. It provides granular metrics (both of itself and of downstream services), distributed tracing, TLS, a powerful logical routing layer, and integration with most common service discovery mechanisms.
Applications use linkerd by proxying HTTP, gRPC, or Thrift calls through a local linkerd instance. In many cases, integration with linkerd is a config change (e.g. setting an http_proxy environment variable) rather than a code change. Linkerd acts as a transparent proxy, and so a call to (e.g. "http://foo/bar") will be routed to the appropriate cluster, resolved in service discovery, load balanced, retried, and returned without application code being aware.
Linkerd is built on top of Finagle (https://twitter.github.io/fin
agle/), the high-concurrency RPC library that powers companies like Twitter, Soundcloud, Pinterest, and ING Bank. By staying close to the Finagle codebase, linkerd takes advantage of Finagle’s extensive production usage (https://github.com/twitter/fi nagle/blob/develop/ADOPTERS.md ). Linkerd’s primary author is a core contributor to Finagle.

Statement on alignment with CNCF mission:
Linkerd directly addresses the communications challenges of running microservices at scale, and integrates directly with orchestrated environments such as Kubernetes and DC/OS. Linkerd integrates with two existing CNCF projects: it can use the Kubernetes API directly as a service discovery mechanism, and it exposes metrics in Prometheus format. See this blog post (https://blog.buoyant.io/2016/
10/04/a-service-mesh-for-kuber netes-part-i-top-line-service- metrics/) for an example of linkerd, Kubernetes and Prometheus working together.
