```bash
# Deploy model using CLI
mlops deploy --model-name="my-model" --model-version=1 --environment=production

# Or using the Python API
from mlops_production_system.deployment import ModelDeployer

deployer = ModelDeployer()
deployer.deploy(model_name="my-model", model_version=1, environment="production")
```

### Monitoring

```python
from mlops_production_system.monitoring import DriftDetector, PerformanceMonitor

# Monitor for drift
drift_detector = DriftDetector(reference_data="data/reference.parquet")
drift_results = drift_detector.detect(new_data="data/production_data.parquet")

# Monitor model performance
performance_monitor = PerformanceMonitor(model_name="my-model", model_version=1)
performance_metrics = performance_monitor.get_metrics(timeframe="last_24h")
```

## 🔄 CI/CD Pipeline

The system uses GitHub Actions for CI/CD pipeline, configured in `.github/workflows/main.yml`. The pipeline includes:

1. **Code Quality**:
   - Linting with flake8
   - Type checking with mypy
   - Security scanning with bandit

2. **Testing**:
   - Unit tests with pytest
   - Integration tests
   - Code coverage reporting

3. **Model Validation**:
   - Performance benchmarking
   - Model quality checks
   - Validation against baseline metrics

4. **Deployment**:
   - Docker image building
   - Image pushing to container registry
   - Kubernetes deployment updates

All secrets and credentials are stored securely in GitHub Secrets and only accessed during workflow execution.

### Contributing

We follow the GitFlow branching model:

1. Create a feature branch from `develop`: `git checkout -b feature/your-feature`
2. Make your changes and commit: `git commit -m "Add feature"`
3. Push your branch: `git push origin feature/your-feature`
4. Open a Pull Request against the `develop` branch

All PRs must pass CI checks and code review before being merged.

## 🔬 Advanced Usage

### Distributed Training

The system supports distributed training using PyTorch's DistributedDataParallel for efficient multi-node training:

```yaml
# Example Kubernetes configuration in infrastructure/kubernetes/distributed-training.yaml
apiVersion: batch/v1
kind: Job
metadata:
  name: distributed-training
spec:
  parallelism: 4
  template:
    spec:
      containers:
      - name: trainer
        image: your-registry/mlops-trainer:latest
        resources:
          limits:
            nvidia.com/gpu: 1
        env:
        - name: WORLD_SIZE
          value: "4"
```

### A/B Testing

The A/B testing framework allows comparing multiple models in production:

```python
from mlops_production_system.monitoring import ABTestingFramework

# Set up A/B test between two models
ab_test = ABTestingFramework()
ab_test.create_experiment(
    name="pricing_model_comparison",
    models=["pricing_model_v1", "pricing_model_v2"],
    traffic_split=[0.5, 0.5],
    evaluation_metric="conversion_rate"
)

# Get results
results = ab_test.get_results(experiment_name="pricing_model_comparison")
```

### Drift Detection

Detect data drift to trigger model retraining:

```python
from mlops_production_system.monitoring import DriftDetector

# Initialize with reference data distribution
detector = DriftDetector(
    reference_data="s3://bucket/reference_data.parquet",
    features=["feature1", "feature2", "feature3"],
    drift_method="wasserstein",
    threshold=0.1
)

# Check for drift in new data
drift_detected, drift_metrics = detector.detect(
    current_data="s3://bucket/production_data.parquet"
)

if drift_detected:
    # Trigger retraining
    from mlops_production_system.training import trigger_retraining
    trigger_retraining(model_name="my-model")
```

## 🔒 Security

This project follows security best practices:

- Secrets management via environment variables and Kubernetes secrets
- Regular dependency scanning for vulnerabilities
- Least privilege principle for all service accounts
