# Advanced Implementation (Level 3)

## Advanced Scaling Strategies

```python
class RailwayScalingManager:
    def __init__(self):
        self.railway_client = RailwayClient()
        self.metrics_analyzer = MetricsAnalyzer()
        self.cost_optimizer = CostOptimizer()
    
    async def implement_intelligent_scaling(self, 
                                          project_id: str,
                                          scaling_config: ScalingConfiguration) -> ScalingImplementation:
        """Implement intelligent auto-scaling for Railway services."""
        
        # Analyze current usage patterns
        usage_analysis = await self.metrics_analyzer.analyze_usage_patterns(
            project_id, timeframe="7d"
        )
        
        # Configure predictive scaling
        predictive_config = self._configure_predictive_scaling(
            usage_analysis,
            scaling_config
        )
        
        # Set up cost optimization
        cost_optimization = self.cost_optimizer.optimize_scaling_costs(
            predictive_config,
            scaling_config.budget_constraints
        )
        
        return ScalingImplementation(
            scaling_rules=self._create_scaling_rules(predictive_config),
            monitoring_setup=self._setup_scaling_monitoring(),
            cost_controls=cost_optimization,
            performance_alerts=self._configure_performance_alerts()
        )
```

### Database Optimization Patterns

```typescript
// Railway PostgreSQL optimization with connection pooling
import { Pool } from 'pg';

// Production-ready database configuration
const productionPool = new Pool({
  connectionString: process.env.DATABASE_URL,
  ssl: { rejectUnauthorized: false },
  
  // Optimized for Railway's containerized environment
  max: 20, // Maximum connections in pool
  min: 5,  // Minimum connections to maintain
  idleTimeoutMillis: 30000, // Close idle connections after 30s
  connectionTimeoutMillis: 2000, // Give up connecting after 2s
  statement_timeout: 10000, // Kill slow queries after 10s
  
  // Connection retry logic
  retry: 3,
  retryDelay: 1000,
});

// Application database service
export class DatabaseService {
  private pool = productionPool;
  
  async query<T>(text: string, params?: any[]): Promise<T[]> {
    const start = Date.now();
    const client = await this.pool.connect();
    
    try {
      const result = await client.query(text, params);
      const duration = Date.now() - start;
      
      // Log slow queries for optimization
      if (duration > 1000) {
        console.warn('Slow query detected:', {
          query: text,
          duration,
          rowCount: result.rowCount
        });
      }
      
      return result.rows;
    } finally {
      client.release();
    }
  }
  
  async transaction<T>(callback: (client: any) => Promise<T>): Promise<T> {
    const client = await this.pool.connect();
    
    try {
      await client.query('BEGIN');
      const result = await callback(client);
      await client.query('COMMIT');
      return result;
    } catch (error) {
      await client.query('ROLLBACK');
      throw error;
    } finally {
      client.release();
    }
  }
}

// Health check endpoint
app.get('/api/health', async (req, res) => {
  try {
    await db.query('SELECT 1');
    res.status(200).json({ 
      status: 'healthy',
      timestamp: new Date().toISOString(),
      database: 'connected'
    });
  } catch (error) {
    res.status(503).json({ 
      status: 'unhealthy',
      timestamp: new Date().toISOString(),
      database: 'disconnected'
    });
  }
});
```

### Environment Management

```python
class RailwayEnvironmentManager:
    def __init__(self):
        self.railway_client = RailwayClient()
        self.config_manager = ConfigurationManager()
    
    def setup_production_environment(self, project_id: str, config: EnvironmentConfig) -> EnvironmentSetup:
        """Configure production environment with best practices."""
        
        # Set up production variables
        production_vars = {
            # Application configuration
            'NODE_ENV': 'production',
            'LOG_LEVEL': 'info',
            
            # Database configuration
            'DATABASE_URL': config.database_url,
            'DATABASE_POOL_SIZE': '20',
            'DATABASE_TIMEOUT': '10000',
            
            # Security configuration
            'JWT_SECRET': config.jwt_secret,
            'ENCRYPTION_KEY': config.encryption_key,
            'CORS_ORIGIN': config.frontend_url,
            
            # External services
            'REDIS_URL': config.redis_url,
            'EMAIL_SERVICE_API_KEY': config.email_api_key,
            
            # Monitoring and observability
            'SENTRY_DSN': config.sentry_dsn,
            'LOGTAIL_SOURCE_TOKEN': config.logtail_token
        }
        
        # Configure environment variables
        env_setup = self.railway_client.set_environment_variables(
            project_id, production_vars
        )
        
        return EnvironmentSetup(
            variables=production_vars,
            security_config=self._configure_security(),
            monitoring_config=self._configure_monitoring(),
            backup_config=self._configure_backups()

## Best Practices (November 2025)

### DO
- Use separate environments for development, staging, and production
- Implement comprehensive health checks for all services
- Configure proper logging and monitoring for observability
- Use connection pooling for database connections
- Set up automated testing before deployments
- Monitor costs and implement spending limits
- Use volume mounts for persistent data storage
- Implement proper error handling and retry logic

### DON'T
- Hardcode environment variables in application code
- Skip health checks and monitoring setup
- Use production database for development testing
- Ignore scaling limits and cost controls
- Deploy without proper testing
- Forget to implement backup strategies
- Overprovision resources without optimization
- Skip security configuration for production
