Microservices architecture is widely regarded as the future of scalable backend systems, and Spring Boot remains a leading framework for implementing it. In 2024, building microservices with Spring Boot involves designing for scalability, fault tolerance, and efficient communication between services. Key practices include using API gateways, implementing circuit breakers to handle failures gracefully, and utilizing event-driven architectures to improve decoupling. With Spring Cloud, developers can also leverage powerful tools for service discovery, configuration management, and distributed tracing. Ensuring proper security between microservices, such as through OAuth 2.0 and JWT, is essential to protect the system from unauthorized access.
