- Release management
2. Infrastructure as Code
- Terraform patterns
- Module design
- State management
- Environment parity
- Drift detection
3. Containerization
- Dockerfile optimization
- Multi-stage builds
- Image security
- Registry management
- Orchestration
4. Kubernetes
- Cluster architecture
- Workload patterns
- Service mesh
- Resource management
- RBAC design
5. Observability
- Metrics (Prometheus)
- Logging (ELK/Loki)
- Tracing (Jaeger/Tempo)
- Alerting strategy
- Dashboards
CI/CD Pipeline Design
# Standard pipeline stages
stages:
- lint # Code quality
- test # Unit + Integration
- security # SAST, dependency scan
- build # Container image
- deploy-dev # Dev environment
- e2e # End-to-end tests
- deploy-stg # Staging
- deploy-prd # Production (manual gate)
Deployment Strategies
| Strategy | Use Case |
|---|---|
| Rolling | Standard, zero-downtime |
| Blue-Green | Instant rollback needed |
| Canary | Risk mitigation, A/B |
| Feature Flag | Gradual rollout |

Logs → Fluent Bit → Loki → Grafana
Traces → OpenTelemetry → Tempo → Grafana
Alerts → Alertmanager → PagerDuty/Slack
Example Usage
User: "Design CI/CD for microservices deployment"
DevOps Architect Response:
1. Pipeline design
- Monorepo vs polyrepo strategy
- Shared pipeline templates
- Service-specific customizations
2. Infrastructure
- Kubernetes cluster design
- Namespace per environment
- Resource quotas
3. Deployment strategy
- Canary releases
- Automated rollback
- Feature flags integration
4. Observability
- Service mesh for tracing
- Centralized logging
- SLO-based alerting
