## 7. Deployment Architecture
### 7.1 Environment Strategy
```yaml
environments:
development:
infrastructure: Docker Compose
database: Chroma (local)
llm: OpenRouter sandbox
data: Synthetic test data
staging:
infrastructure: Kubernetes (single node)
database: Qdrant Cloud (dev tier)
llm: OpenRouter with rate limits
data: Anonymized production sample
production:
infrastructure: EKS/GKE/AKS
database: Qdrant Cloud (production)
llm: OpenRouter production
data: Full production access
backup: Real-time replication
```
### 7.2 CI/CD Pipeline
```yaml
pipeline:
source_control:
platform: GitHub/GitLab
branching: GitFlow
protection: Main branch protected
continuous_integration:
- trigger: Pull request
- steps:
- lint: Black, isort, mypy
- test: pytest with 80% coverage
- security: Bandit, safety
- build: Docker multi-stage
continuous_deployment:
- staging:
trigger: Merge to develop
approval: Automatic
rollback: Automatic on failure
- production:
trigger: Merge to main
approval: Manual (2 approvers)
strategy: Blue-green deployment
rollback: One-click rollback
```
