DevOps

Go live with a switch, not a deployment.

The code is already in production, switched off. Going live is switching the release on there — and switching a feature off is how you undo it.

Switch the release on in production — every feature in it, across applications, at once. Releases
Production keeps its own release switch — a new release arrives there off, and promotion never changes it: going live stays your decision. Promotion
Stop a feature in seconds — switch a misbehaving feature off for new work, with no redeploy; every switch is recorded: who, what and when.
Only the people you name — your identity provider decides who may promote into production and switch releases there. Security & access
No code or configuration change per environment — each environment supplies FTF's address and its key; the same build runs everywhere.
