Zero-Downtime Deployment
Quick Reference
What & Why
Definition
>= 80% of deployments achieve zero downtime using rolling updates or blue-green strategy.
Business Value
Eliminates 90% of environment-specific deployment failures and reduces deployment preparation time from 3 hours to 20 minutes through infrastructure as code Achieving >= 80% deployments zero downtime is a key milestone toward this goal.
Context
This capability is part of the Foundation milestone's focus on establish baseline practices (testable, releasable, monitorable). Essential for teams targeting DF, MTTR improvements.
Success Criteria
>= 80% deployments zero downtime
Measurement
Uptime monitoring during deployments
Evidence
- Deployment strategy config
- Uptime charts during deploys
- Health check logs
In Practice
Real-World Implementation
Teams use Kubernetes rolling updates with readiness probes, ensure >= 2 replicas running, gradual traffic shift.

Troubleshooting & FAQs
Common Issues
Issue: Target metric not improving
Solution: Verify measurement is accurate, check if prerequisites are fully implemented, review evidence artifacts for completeness
Issue: Team resistance to adoption
Solution: Start with pilot team, demonstrate value with metrics, provide training and support during transition
Issue: Inconsistent implementation across teams
Solution: Create shared templates and guidelines, establish regular sync meetings, use automation to enforce standards
Frequently Asked Questions
Can we implement this before completing prerequisites?
While possible, it's not recommended. Prerequisites ensure foundational practices are in place, making this capability more effective and easier to adopt.
How long does implementation typically take?
Most capabilities can be implemented within 90 days when tackled as part of the Foundation milestone. Individual timelines vary based on team size and existing practices.
