Maturity Assessment
DevOps Maturity Levels:
Basic:
- Manual deployments
- No CI/CD detected
- Minimal automation
Intermediate:
- CI/CD pipeline detected
- Containerization (Docker)
- Basic monitoring
Advanced:
- Full CI/CD with multiple stages
- Container orchestration (K8s)
- Infrastructure as Code
- Comprehensive monitoring
Cloud-Native:
- GitOps practices (ArgoCD)
- Service mesh
- Observability stack
- Multi-cloud or hybrid
Error Handling
- Private repositories: Note as limitation
- Incomplete config analysis: Provide partial results
- Job posting only signals: Lower confidence
