Unleashing Deploy Velocity with Feature Flags

A lot of development teams have built out fully automated CI/CD pipelines to deliver code to production fast! Then you quickly discover that the new bottleneck in delivering features is their existence in long-lived feature branches and no true CI is actually happening. This problem compounds as you start spinning up microservices and building features across your multi-repo architecture and coordinating some ultra-fancy release schedule so it all deploys together. Feature flags provide you the mechanism to reclaim control of the release of your features and get back to short-lived branches with true CI. However, what you're not told about feature flags in those simple "if/else" getting started demos is that there is an upfront cost to your development time, additional complexities, and some pitfalls to be careful of as you begin expanding feature flag usage to the organization. If you know how to navigate these complexities you will start to unleash true velocity across your teams. In this talk, we'll get started with some of the feature flagging basics before quickly moving into some practical feature flagging examples that demonstrate its usage beyond the basic scenarios. Along the way we will pull in context and discuss how SPS Commerce has used feature flags to impact their day-to-day development patterns. This session is presented by LaunchDarkly.
