Production-Safety

Feature Flags: Safer Deployments, Faster Feedback Feature flags, or toggles, are small switches in code that turn a feature on or off without a new build. They let teams deploy changes safely while deciding when customers will see them. Flags separate the act of deploying from the act of releasing, which reduces risk and gives you more control. Used well, flags help you limit problems to a small user group and learn quickly. If a new UI or payment option behaves oddly, you can disable it in seconds and collect diagnostics without a full rollback. This makes incidents easier to repeat, diagnose, and fix. ...

Testing in Production Safety and Strategies Testing in production is not reckless experimentation. It is a disciplined approach that uses controlled exposure to learn fast while protecting users. With guardrails, you can validate behavior under real load and data, not just in a lab. Why test in production? Production data reveals edge cases staging can miss. Real users, live traffic, and external services can behave differently. Safe prod testing relies on observability, fast rollback, and small blast radii. ...
