    or, How I learned to Stop Worrying and Love the JVM

    Kevin Corcoran@KevinOfCorc

  • why?

  • difficult to change difficult to understand still really valuable performance, scale

    MRI + GIL Passenger

    lack of coordination between processes

    WEVE ALL GOT PROBLEMS

  • JVM ...

  • CHALLENGES

    puppet apply a first-class citizen

    JVM on master only no parallel implementations continue to use Ruby

  • It has to just work.

    It has to be fast.(trademark pending)

  • lifecycle state

    management configuration logging packaging code

    modularity, reuse

  • WHATS A TRAPPERKEEPER?

    open-source Clojure application framework

    Service Service API vs. implementation foundation for server-side apps

    PuppetDB Puppet Server Classifier / Node Manager RBAC

    Yes, in production. latest version: 1.0.3 part of PE 3.7.x it works like a champ - Trevor

    STATUS

  • LIES, DAMNED LIES, AND BENCHMARKS

    simulated HTTP traffic via Gatling

    Puppet 3.7.0 ~1000 resources master host:

    CentOS 6 4-core Xeon 3.6GHz 8 GB RAM

  • LIES, DAMNED LIES, AND BENCHMARKS

    ~2x faster @ 1000 nodes

    ~3x faster @ 2000 nodes

    performance barely affected by 2x as many agents
