    The last decade belonged to virtual machines, the next one belongs to containers. Virtualization lead to an explosion in the number of machines in our infrastructure and we were all caught off guard. It turns out that those shell scripts did not scale after all. Lucky for us configuration management swooped in to save the day. But a new challenge is on the horizon. We are moving away from node based infrastructures where hostnames are chosen with care. Gone are the days of pinning one service to a specific host and wearing a pager in case that host goes down. Containers enable a service to run on any host at any time. Our current set of tools are starting to show cracks because they were not designed for this level of application portability. It’s time to get ahead of the curve and take a look at new ways to deploy and manage applications at scale. Introducing CoreOS...CoreOS is a new Linux distribution designed specifically for application containers and running them at scale. This talk will examine all the major components of CoreOS including etcd, fleet, docker, and systemd; and how these components work together to solve the problems of today and tomorrow.

        In the course of their day-to-day work, our development team actively relies on our metrics platform to confidently ship code to production and debug problems. They measure and correlate behavior between services on live production workloads, use real-time data to reason and hypothesize about production problems, and add or modify metrics and instrumentation in production to prove out their assumptions. Our own success in utilizing the metrics stream from production to close our engineering feedback loop, has convinced us that this, practice, which we describe as Metrics Driven Development (MDD), is a requirement of building web-scale systems. It is a discipline that should be implemented by development teams alongside other development paradigms like Test-driven-development (TDD) and Behavior-Driven-Development (BDD). Our talk will recount an episode where we employed MDD to diagnose an actual problem encountered in our production system running at scale. The audience will follow as the developer initially identified an anomaly in a production KPI metric, developed a hypothesis as to the cause of the anomaly, added instrumentation to the code in question and finally confirmed the original hypothesis through observation of real-time metrics. Along the way we’ll include references to specific tools and best practices that developers can adopt in their own MDD efforts. We’ll also demonstrate that MDD does not replace traditional debugging approaches like request logging or code profiling, but can often help narrow the focus of those efforts, which can be expensive or difficult to perform in web-scale systems. This talk is a synthesis of cultural transformation, concrete engineering techniques, systems monitoring, scientific observation, and post-mortem. It will prove intellectually gratifying and valuable to anyone who is writing and shipping code to production systems, even if they are already following an MDD model. They’ll learn what requirements a metrics platform needs to support MDD, how to add lightweight instrumentation to code, and how to isolate problems by using metrics derived from that instrumentation. The audience will also see how MDD can be used in addition to traditional production debugging practices, and will come away with an understanding of how to ship better software through the use of MDD.

          Graphite and Statsd are indispensable components of the modern DevOps stack. Companies such as Etsy have demonstrated that instrumenting your business and being a data driven organization can improve the lives of your teams and be useful to help improve your products and your customers' experience. Unfortunately running Graphite at scale is non-trivial. Acquia has matured over the years in its internal usage of Graphite and has learned many lessons along the way. Come learn how we have scaled Graphite using Cassandra to store millions of data points all the while giving back to open source.

              Erich and Luke cover how they’ve built a scalable, self-healing DevOps environment in record time for an EMS and acute care platform. By using Vagrant, Packer, AWS, and other technologies to standardize across development and production environments they managed to give their developers greater control and more hours of worry free sleep.

                    Cucumber is a popular platform for building test suites that are easy for business stakeholders to understand. In this session, we'll introduce and compare traditional JUnit-style tests with Cucumber-style BDD testing. We'll show how to add in Selenium-based testing to automate UI/browser testing, and then we'll show how to use PhantomJS to run those Selenium tests quickly. We'll also talk about how this integrates into a continuous integration environment, and walk through an example of how all of this is hooked together on GitHub.
