Learning Notes
DevOps Professional Certificate
Validated practical DevOps foundations, including modern deployment flows and incident-aware operations.
CI/CD designOn-call operationsReliability monitoring
What I Learned
- Design a CI/CD path from commit validation to controlled production release.
- Configure on-call readiness with clear alert priorities and escalation paths.
- Use observability signals to reduce mean time to detect and mean time to recover.
How I Applied This
- Built release checks so pull requests fail early before risky deployments.
- Set up on-call runbooks so incidents move from alert to resolution faster.
- Connected deployment metrics to uptime goals for better delivery decisions.
