Finagle and Mesos are two core technologies used by Twitter and many other companies to scale application infrastructure to high traffic workloads. In this talk, we describe how these two technologies work together to form applications that are both highly scalable and resilient to failure. We introduce linkerd, an open-source proxy form of Finagle, which extends Finagle's operational model to non-JVM or polyglot microservices. Finally, we show how linkerd can be used to "wrap" applications running on Mesos to provide higher-level, service-based semantics around scalability, reliability, and fault-tolerance for microservices---even in the presence of unpredictable traffic volumes and unreliable hardware.
