The Foundation of Safer, Near-Zero-Downtime Deployments

A safe release is repeatable and reversible, separating build work from switching traffic to the new version.

A practical framework

Build each release in its own directory, install and verify it, then atomically switch the current symlink. Keep prior releases and stage backward-compatible database migrations.

Checklist

• Back up before migrations
• Run post-deploy health checks
• Test the rollback path
• Keep environment secrets out of Git

The next step

Choose one decision you can apply this week, assign an owner and success signal, then review the result before expanding scope.
