📄️ 11 Principles for building and scaling feature flag systems
Feature flags, sometimes called feature toggles or feature switches, are a software development technique that allows engineering teams to decouple the release of new functionality from software deployments. With feature flags, developers can turn specific features or code segments on or off at runtime, without the need for a code deployment or rollback. Organizations who adopt feature flags see improvements in all key operational metrics for DevOps: Lead time to changes, mean-time-to-recovery, deployment frequency, and change failure rate.
📄️ Best Practices for Migrating from a Homegrown Feature Management Solution
Many large organizations have an existing feature management solution that they have outgrown and plan to migrate to a feature flag service.
📄️ A/B and multivariate testing
A/B testing is a type of randomized controlled experiment, where you test two different versions of a feature to see which version performs better. If you have more than two versions, it's known as multivariate testing. Coupled with analytics, A/B and multivariate testing enables you to better understand your users and how you can serve them better.
