Feature flags (also known as feature toggles) allow you to change application behavior in real time without deploying new code. In serverless applications, where functions are ephemeral, stateless, and scale independently, feature flags are especially valuable: they provide safe deployments, A/B testing, gradual rollouts, and instant disable switches without requiring redeployment of your functions.
Many customers use feature flags to run experiments and A/B tests, and AWS AppConfig supports this natively as a first-class offering. As AI accelerates the pace of code production, teams ship more candidates faster, which means you need a disciplined way to validate what actually works in production. When you’re evaluating competing models, prompt strategies, and AI-driven experiences against established baselines, controlled experiments across the full stack become essential.
AWS AppConfig Experimentation lets you define multi-variate flags, allocate traffic by…
