Health Checks + +**9.1. Implement Health Endpoints** +```python +# Add to backend +@app.get("/health") +async def health_check(): + return { + "status": "healthy", + "services": { + "database": await check_database(), + "milvus": await check_milvus(), + "rag_service": await check_rag_service() + } + } +``` + +**9.2. Monitor with Uptime Robot or Similar** +``` +- Check /health endpoint every 5 minutes +- Alert on failures via email/SMS/Slack +- Monitor from multiple regions +``` + +### 10. Scaling Considerations + +**10.1. Horizontal Scaling** +```yaml +# docker-compose.prod.yml (with scaling) +services: + backend: + deploy: + replicas: 3 + resources: + limits: + cpus: '1' + memory: 2G + + rag-service: + deploy: + replicas: 2 + resources: + limits: + cpus: '2' + memory: 4G +``` + +**10.2. Load Balancing** +``` +- Use AWS ALB, GCP Load Balancer, or Nginx +- Enable session affinity if needed +- Configure health checks +- Set up auto-scaling based on metrics +``` + +## Troubleshooting + +### Common Issues + +**1.

Flow Execution Security + +**CRITICAL: Flows can execute arbitrary Python code** + +**Current State:** No sandboxing or validation +- Flows run in the same process as the API +- No resource limits +- No code validation +- Can access file system and network + +**Required Mitigations:** +1. **Sandboxing:** Run flows in isolated containers + ```yaml + # Docker-in-Docker or separate worker containers + - Separate execution environment + - Limited network access + - Read-only file system + - Resource limits (CPU, memory, time) + ``` + +2. **Validation:** Validate flow JSON before execution + ```python + - JSON schema validation + - Whitelist allowed components + - Check for malicious patterns + - Scan for sensitive data access + ``` + +3. **Approval Workflow:** Require manual approval for untrusted flows + ``` + - Review queue for new flows + - Admin approval before execution + - User reputation system + - Automated security scanning + ``` + +### 4. Input Validation + +**Current State:** Minimal validation + +**Required Improvements:** +- Validate all file uploads (type, size, content) +- Sanitize all text inputs +- Limit payload sizes +- Validate JSON structure +- Check for SQL injection patterns +- Prevent XXE attacks in XML/JSON +- Rate limit uploads + +**Example:** +```python +# File upload limits +MAX_FILE_SIZE = 10 * 1024 * 1024 # 10 MB +ALLOWED_EXTENSIONS = {'.json', '.txt', '.pdf', '.jpg', '.png'} + +# Text input limits +MAX_TEXT_LENGTH = 50000 # characters +MAX_BATCH_SIZE = 100 # items +``` + +### 5. Rate Limiting + +**Current State:** Basic slowapi rate limiting + +**Production Configuration:** +```python +# Adjust based on your needs +- API endpoints: 100 requests/minute per IP +- Authentication: 5 attempts/minute per IP +- File uploads: 10 uploads/hour per user +- RAG queries: 60 queries/minute per user +- Embedding generation: 100 items/hour per user +``` + +**Advanced Features:** +- User-based rate limiting (not just IP) +- Dynamic rate limits based on subscription tier +- Distributed rate limiting (Redis) +- Rate limit headers in responses +- Exponential backoff for repeated violations + +### 6. Secrets Management + +**NEVER commit secrets to git** + +**Current Issues:** +- Hardcoded JWT secret +- Default credentials in docker-compose +- API keys in plaintext + +**Solutions:** +```bash +# Use environment variables +export JWT_SECRET_KEY=$(openssl rand -hex 32) +export DATABASE_URL="postgresql://..." +export OPENAI_API_KEY="sk-..." + +# Use secrets management services +- AWS Secrets Manager +- Azure Key Vault +- HashiCorp Vault +- Docker Secrets +- Kubernetes Secrets +``` + +**Update `.gitignore`:** +``` +.env +.env.local +.env.production +*.key +*.pem +secrets/ +``` + +### 7. Database Security + +**Current State:** In-memory fake database + +**Production Requirements:** +- Use a real database with authentication +- Encrypt data at rest +- Use prepared statements (prevent SQL injection) +- Regular backups with encryption +- Limit database user permissions +- Monitor for suspicious queries +- Enable audit logging + +### 8. Network Security + +**Required Configurations:** +```yaml +# Use HTTPS/TLS for all services +- Frontend: HTTPS with valid certificate +- Backend API: HTTPS only +- Internal services: mTLS for service-to-service + +# Firewall rules +- Restrict Milvus, Etcd, MinIO to internal network only +- No direct external access to databases +- Use VPN for administrative access +``` + +### 9.
