Kubernetes meets Finagle for Resilient Microservices

by Oliver Gould

Published March 10, 2016 in Technology

Finagle is an open-source, high-volume RPC client library, handling millions of QPS at companies like Twitter, Pinterest and Soundcloud. In this talk, we demonstrate how Finagle can be applied to Kubernetes applications via linkerd, an open-source, standalone Finagle proxy. By deploying linkerd as a sidecar container or with DaemonSets, we show how polyglot multi-service applications running in Kubernetes can be “wrapped” in Finagle’s operational model, adding connection pooling, load-balancing, failure detection, and failover mechanisms to existing applications with minimal code change. We demonstrate how linkerd communicates with the Kubernetes API and how the resulting systems perform under load and adverse conditions.
