🎯 Best Practices

1. Configuration Management

- Use environment-specific configuration files - Implement configuration validation - Use secure environment variables for sensitive data - Implement configuration hot-reloading

2. Security

- Implement zero-trust security model - Use JWT with proper expiration - Enable MFA for sensitive operations - Implement rate limiting - Use SSL/TLS for all communications

3. Observability

- Implement distributed tracing - Use structured logging - Set up comprehensive metrics - Configure alerting rules - Monitor performance indicators

4. Performance

- Use connection pooling - Implement caching strategies - Configure thread pools appropriately - Enable compression - Monitor resource usage

5. Resilience

- Implement circuit breakers - Use retry mechanisms - Configure timeouts - Implement graceful degradation - Monitor health checks

🔧 Troubleshooting

Common Issues

1. Configuration Loading Failures - Check file permissions - Verify environment variables - Validate TuskLang syntax - Check database connectivity

2. Performance Issues - Monitor connection pool usage - Check cache hit rates - Analyze thread pool utilization - Review database query performance

3. Security Issues - Verify JWT configuration - Check SSL certificate validity - Review access control lists - Monitor failed authentication attempts

4. Observability Issues - Check tracing configuration - Verify metrics collection - Review log levels - Test alerting rules

Debug Commands

Check configuration

java -jar user-service.jar --config-validate

Test database connectivity

java -jar user-service.jar --test-db

Verify security configuration

java -jar user-service.jar --security-check

Performance profiling

java -jar user-service.jar --profile

🚀 Next Steps

1. Implement the patterns in your microservices 2. Configure observability for production monitoring 3. Set up security with zero-trust principles 4. Optimize performance based on metrics 5. Scale horizontally using the patterns
