Kill Switch - CI/CD Glossary Definition
A kill switch is a flag dedicated to instantly turning off a misbehaving feature in production without deploying.
A kill switch is a feature flag whose specific purpose is to instantly disable a feature or subsystem in production when it misbehaves, without a deploy. It is a fast, targeted rollback mechanism.
Kill switches are pre-wired around risky features so an operator can shut them off during an incident in seconds.
