Leg 5 of the journey

It Holds: deployment, monitoring, and the flag moment

Go-live with monitoring, alerting, and rollback paths, so when something breaks you hear it from the system first.

What happens on this leg

• Monitored deployment with alerting on the failure modes that matter
• Rollback paths planned before they are needed
• Live dashboards reading from one source of truth
• The flag moment: the system holds under real load

What you leave with

You leave with a running system your team can watch, measured from one truth, with nobody guessing.

deployment is a beginning you can see, not a handoff and a prayer
