Layer Responsibilities

🔌 Extending with AI Services

Add Your AI Provider

1. Install your AI SDK:

pip install openai  # or anthropic, cohere, etc.

2. Configure environment:

# Add to .env
AI_SERVICE_API_KEY=sk-your-api-key
AI_SERVICE_MODEL=gpt-4

3. Implement service integration:

# In service layer
class AIService:
    async def generate_response(self, query: str, context: dict) -> str:
        # Your AI integration here
        return ai_response

📊 Monitoring & Observability

Health Metrics

• ✅ Service uptime
• 🔗 Database connectivity
• 📈 Request rates
• ⏱️ Response times
• 💾 Memory usage

Logging

# Structured logging included
{
  "timestamp": "2024-02-14T12:00:00Z",
  "level": "INFO",
  "message": "Query processed",
  "request_id": "req_123456",

}

🔒 Security

Built-in Security Features

• 🔐 Token Authentication - Secure API access
• 🛡️ Rate Limiting - DoS protection
• ✅ Input Validation - SQL injection prevention
• 📝 Audit Logging - Request tracking
• 🔒 Environment Secrets - Secure config management

🚀 Deployment

Environment Setup

# Production environment variables
DATABASE_URL=postgresql://prod-user:password@prod-host/db
RATE_LIMIT_REQUESTS=1000
LOG_LEVEL=WARNING

Scaling Considerations

• Use connection pooling for database
• Implement Redis for rate limiting in multi-instance setups
• Add load balancer for high availability
• Monitor with Prometheus/Grafana
