🎯 Architecture Highlights

🏗️ Microservices Pattern

• Service-oriented architecture with clear separation of concerns
• Independent deployment and scaling for each service
• API Gateway for unified entry point and cross-cutting concerns

💾 Data Layer

• PostgreSQL with advanced features (partitioning, indexing)
• Redis for high-speed caching and session management
• Alembic for database schema versioning

🔄 Communication

• HTTP/REST APIs with OpenAPI documentation
• Kafka for asynchronous event-driven communication
• WebSocket ready for real-time features

🛡️ Security & Reliability

• JWT authentication with secure token handling
• Rate limiting and DDoS protection
• Health checks and monitoring integration
• Graceful error handling and logging

📈 Scalability Features

• Async/await pattern for high concurrency
• Connection pooling for optimal database performance
• Horizontal scaling ready with container orchestration
• Caching strategies for performance optimization

🚀 Quick Start Commands

# Setup and start all services
./start_services.sh

# Test all APIs
python test_api.py

# Stop all services
