Explore systematic experimentation in scalable and repeatable environments with insights from experts Xuan Liu, Gary Wong, Paul Ruth, and others. Learn how to start small, focus on one variable at a time, and effectively manage your work with case studies like virtual router failure restoration. This session includes practical applications such as writing scalable ExoGENI velocity scripts, manipulating RSpecs, and utilizing `geni-lib` to build small applications for experimenters, as well as transitioning images between ExoGENI and InstaGENI platforms.
