  • Stack Smashing

    by David Czarnecki

    "Stack Smashing" refers to an internal project where I took our production Rails application environment down from over 100 virtual machines to 2 physical machines. Our application environment for Major League Gaming consists of 13+ inter-connected applications with millions of users to provide functionality such as single-sign on, online video (both video on demand and UGC), news and live competition information, photo galleries, profiles, and much more. We simply needed a simpler infrastructure in which to develop and deploy our applications. In this talk, we will cover the following:

    • Network topology before and after, as well as the makeup of our virtual and physical machines.
    • Detailed discussion of Chef recipes, NGINX, HAProxy configurations and updates to standard configurations.
    • Application and service monitoring and configuration.
    • Application migration from the old stack to the new stack.
    • Rails 3 to Rails 3.1 upgrade insights.
    • Unicorns!
    • Strategies for service configuration to handle failure.
    • Offline processing with queueing and queue management.
    • Simplifying, standardizing and sexy-fying your Capistrano-based deployment tasks into a reusable gem.
    • Behavior driven infrastructure monitoring and validation.
    • Adopting an opt-in continuous deployment strategy that is integrated with our continuous integration environment.

    This will be a very code and example-focused talk. Come and learn about the ways that you can simplify your existing infrastructure.

    At 4:00pm to 4:45pm, Tuesday 24th April

    In Salon H, Hilton Austin Downtown
