The setup
Northwind Pay’s platform team was holding the line on a Jenkins + custom scripts pipeline, a separate observability bill running into six figures, and a PagerDuty rotation that paged on average nine times a night. Mean deploy was 47 minutes. Mean time to acknowledge was longer than the CEO’s patience.
What got replaced
- Jenkins + four plug-ins → Yeinz CI
- Standalone APM + log vendor → Yeinz Observability
- PagerDuty + on-call scheduler → Yeinz Incident Response with native AI summarization
The rollout
Eleven weeks. Started with the payments service in shadow mode. Canary traffic shifted in 5% increments with automated rollback on SLO breach. The on-call rotation adopted Yeinz Incident Response on week six; by week nine Jenkins was off.
