🔧 Best Practices

1. Service Design

- Keep services small and focused - Use database per service pattern - Implement proper API versioning - Use event-driven communication

2. Service Communication

- Use circuit breakers for resilience - Implement retry policies with backoff - Use health checks for service discovery - Implement proper timeout handling

3. Data Management

- Use saga pattern for distributed transactions - Implement eventual consistency - Use event sourcing for audit trails - Implement proper data partitioning

4. Security

- Use JWT for service-to-service authentication - Implement proper authorization - Use network policies for isolation - Encrypt sensitive data

5. Monitoring and Observability

- Use distributed tracing - Implement comprehensive health checks - Monitor service dependencies - Set up proper alerting

🎯 Summary

TuskLang Java microservices architecture provides:

- Service Discovery: Eureka integration for dynamic service registration - API Gateway: Spring Cloud Gateway with routing and filtering - Service Communication: Load balancing and circuit breakers - Distributed Patterns: Saga, CQRS, and event sourcing - Monitoring: Distributed tracing and comprehensive observability

The combination of TuskLang's executable configuration with Java's microservices capabilities creates a powerful platform for building scalable, resilient, and maintainable distributed systems.
