      geocode: `${location.lat},${location.lon}`,
      format: 'json'
    }}
  );
  
  // Correlate weather with performance degradation
  return {
    nodeId,
    weather: weather.data,
    impact_score: calculateImpact(weather.data)
  };
}
\`\`\`

### 6.2 Mapping Services
Visualize infrastructure on maps:

\`\`\`javascript
// Google Maps integration
const map = new google.maps.Map(document.getElementById('map'), {
  center: { lat: 37.7749, lng: -122.4194 },
  zoom: 12
});

// Add infrastructure markers
infrastructure.forEach(node => {
  new google.maps.Marker({
    position: { 
      lat: node.location.latitude, 
      lng: node.location.longitude 
    },
    map: map,
    icon: getIconForNodeType(node.type)
  });
});
\`\`\`

  body: {
    '@timestamp': new Date(),
    node_id: nodeId,
    metrics: telemetryData
  }
});
\`\`\`

#### Prometheus Integration
\`\`\`javascript
const prometheus = require('prom-client');

// Define metrics
const throughput = new prometheus.Gauge({
  name: 'infrastructure_throughput_mbps',
  help: 'Current throughput in Mbps',
  labelNames: ['node_id', 'type']
});

// Update metrics
throughput.set({ 
  node_id: nodeId, 
  type: 'cell_tower' 
}, 2500);
\`\`\`

  "severity": "high",
  "source": {
    "node_id": "550e8400-e29b-41d4-a716-446655440000",
    "ip_address": "192.168.1.10"
  },
  "alert": {
    "type": "unauthorized_access_attempt",

## 8. Testing and Validation

### 8.1 Integration Testing
\`\`\`javascript
describe('Cloud Platform Integration', () => {
  it('should publish telemetry to AWS IoT Core', async () => {
    const result = await publishToAWSIoT(telemetryData);
    expect(result.statusCode).toBe(200);
  });
  
  it('should store data in DynamoDB', async () => {
    await storeInDynamoDB(infraData);
    const retrieved = await getFromDynamoDB(infraData.id);
    expect(retrieved).toEqual(infraData);
  });
});
\`\`\`

### 8.2 End-to-End Testing
\`\`\`python
def test_end_to_end_integration():
    # 1. Collect telemetry
    telemetry = collect_telemetry(node_id)
    
    # 2. Send to WIA API
    response = requests.post(
      'https://api.wiastandards.com/v1/infrastructure/telemetry',
      json=telemetry
    )
    assert response.status_code == 201
    
    # 3. Verify in external system
    time.sleep(2)  # Allow propagation
    external_data = query_external_system(node_id)
    assert external_data == telemetry
\`\`\`

## 9. Migration Strategies

### 9.1 Phased Migration
1. **Assess**: Inventory existing systems
2. **Pilot**: Deploy to 5-10% of infrastructure
3. **Validate**: Test integrations thoroughly
4. **Scale**: Gradual rollout to 100%
5. **Optimize**: Tune performance and costs

### 9.2 Dual-Run Approach
Run old and new systems in parallel:

\`\`\`
Weeks 1-4:  Legacy System (100%) + WIA System (0%)
Weeks 5-8:  Legacy System (75%)  + WIA System (25%)
Weeks 9-12: Legacy System (50%)  + WIA System (50%)
Weeks 13-16: Legacy System (25%)  + WIA System (75%)
Weeks 17+:  Legacy System (0%)   + WIA System (100%)
\`\`\`
