## 📊 Performance Optimization

### For Production:
1. **Enable caching**: Redis configured in docker-compose
2. **Database optimization**: PostgreSQL with proper indexing
3. **Load balancing**: Multiple worker processes
4. **Monitoring**: Built-in health checks

### Scaling:
- **Horizontal**: Multiple container instances
- **Vertical**: Increase CPU/RAM allocation
- **Database**: Separate database server

## 🔒 Security Checklist

- ✅ Environment variables for secrets
- ✅ Non-root Docker user
- ✅ HTTPS in production (handled by platform)
- ✅ Input validation and sanitization
- ✅ Database connection security

## 📈 Monitoring

### Health Check Endpoint:
```
GET /health
```

### Metrics Available:
- Total shipments processed
- ML model accuracy
- Response times
- Error rates

## 🆘 Troubleshooting

### Common Issues:

1. **Port already in use**
   ```bash
   # Change port in docker-compose.yml or .env
   PORT=8051
   ```

2. **Database connection failed**
   ```bash
   # Check DATABASE_URL in .env
   # Ensure database is running
   ```

3. **ML model training fails**
   ```bash
   # Check data format
   # Increase memory allocation
   ```

## 📞 Support

For deployment issues:
1. Check logs: `docker-compose logs dashboard`
