A/B Testing

In my two decades of experience leading DevOps, Digital, and Agile transformations, I’ve observed that the path to modernisation is rarely a straight line. Organisations, particularly those in data-sensitive sectors, like banking, government, and healthcare, often find themselves at a crossroads. They need to innovate faster while maintaining rigorous security and reliability. This tension between speed and safety has traditionally forced companies to choose one over the other. But it doesn’t have to be this way.

Feature toggles are one of those concepts that sound simple on the surface but unlock enormous power in practice. In this DevOps Meetup Zurich session, I team up with Ben Rometsch, founder of Flagsmith, to explain the what, why, and how of feature toggles. We cover the foundational concepts of CI/CD that make feature toggles necessary, the difference between deployment and release, and how modern feature flagging platforms enable progressive rollouts, user segmentation, and A/B testing.
