The evolution of request-driven (RESTful) APIs has led to a one-way, synchronous communication model with clients, resulting in poor user experience, high network traffic, and limited scalability and functionality due to the need for stateless interactions. In contrast, event-driven APIs have gained popularity due to their ability to handle real-time events, improve engagement, flexibility, and resilience through asynchronous communication using publish-subscribe models. A hybrid approach combining RESTful and Event-Driven architectures can provide a more flexible and scalable solution for modern software design, while Edge Stack API Gateway simplifies Kubernetes management with its traffic management controls for resource availability.
