Please 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/finagle/), 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/finagle/blob/develop/ADOPTERS.md). Linkerd’s
primary author is a core contributor to Finagle.

Infrastructure requirements: CI and potentially CNCF Community Cluster
access. We run integration tests per commit (e.g. testing Kubernetes API
integration) and periodic high-volume stress tests.

Community: Active & growing!

Primarily focused on https://slack.linkerd.io (~400 members)

~1200 GitHub stars

~25 contributors

Release methodology and mechanics: Code review on all changes. Releases
triggered manually by developer team. Using pre-1.0 semver semantics.

Social media accounts: Twitter: @linkerd, Slack: http://slack.linkerd.io/

Existing sponsorship: https://buoyant.io/

External Dependencies: Runtime: JVM. Build-time: Finagle, netty

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-kubernetes-part-i-top-line-service-metrics/)
for an example of linkerd, Kubernetes and Prometheus working together.
