When a new application starts, everything feels simple: features look straightforward, the architecture is clean, and launch day goes smoothly. Then the real work begins — a steady flow of new features, refactors, and bug fixes. You need to ship critical fixes fast without revealing unfinished pages or risky changes to customers. As the scope grows — multiple teams, shared dependencies, and large features — coordination gets harder. This is where feature flags help.

Feature flags reduce risk by decoupling deployment from release. Azure App Configuration and Key Vault let you control rollouts safely, target by tenant/segment, and audit changes — without exposing secrets to the browser.
