# 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
