This project demonstrates a comprehensive microservices architecture utilizing Spring Boot, Docker, and a suite of supporting technologies to create a resilient, scalable, and secure application ecosystem. The architecture includes service discovery, configuration management, authentication, message brokering, and different data storage solutions, making it a good blueprint for enterprise-grade applications.

• Spring Boot: Serves as the backbone for creating microservices, offering out-of-the-box support for configuration management, service discovery, and more.
• Docker & Docker Compose: Containerization of services for ease of deployment, scalability, and isolation.
• PostgreSQL: Relational database service instances for order-service and inventory-service.
• MongoDB: Document-based NoSQL database used by product-service.
• Kafka: Message broker facilitating asynchronous communication and event-driven architecture between services.
• Keycloak: Authentication and authorization service providing secure access to services.
• Zipkin: Distributed tracing system for monitoring and troubleshooting latency problems.
• Eureka: Service discovery to automatically detect services in the network.
• API Gateway: Centralized entry point for routing client requests to the appropriate backend service.
