# Integration Patterns

Design patterns for extending and integrating with Provisioning.

## 1. Provider Integration Pattern

Pattern: Add a new cloud provider to Provisioning.

## 2. Task Service Integration Pattern

Pattern: Add infrastructure component.

## 3. Cluster Template Pattern

Pattern: Create pre-configured cluster template.

## 4. Batch Workflow Pattern

Pattern: Create automation workflow for complex operations.

## 5. Custom Extension Pattern

Pattern: Create custom Nushell library.

## 6. Authorization Policy Pattern

Pattern: Define fine-grained access control via Cedar.

## 7. Webhook Integration

Pattern: Trigger Provisioning from external systems.

## 8. Monitoring Integration

Pattern: Export metrics and logs to monitoring systems.

## 9. CI/CD Integration

Pattern: Use Provisioning in automated pipelines.

## 10. MCP Tool Integration

Pattern: Add AI-powered tool via MCP.

## Integration Scenarios

### Multi-Cloud Deployment

Deploy across UpCloud, AWS, and Hetzner in single workflow.

### GitOps Workflow

Git changes trigger infrastructure updates via webhooks.

### Self-Service Deployment

Non-technical users request infrastructure via natural language.

## Best Practices

1. Use type-safe Nickel schemas
2. Implement proper error handling
3. Log all operations for audit trails
4. Test extensions before production
5. Document configuration & usage
6. Version extensions independently
7. Support backward compatibility
8. Validate inputs & encrypt credentials
