Event-Driven Architecture (EDA) has emerged as a pivotal framework in the digital economy, revolutionizing how systems are designed, implemented, and operated. By focusing on the production, detection, and reaction to events, EDA enables systems to be more responsive, scalable, and flexible. This research paper explores various technologies anchored on Event-Driven Architecture and examines their profound impact on the digital economy. Key technologies such as artificial intelligence (AI), the Internet of things (IoT), big data, block chain, 5G, 3Dprinting, robotics and drones are analyzed to understand their roles in enhancing real-time data processing, enabling micro services, and facilitating seamless integration across diverse systems. The study highlights how these technologies contribute to operational efficiency, customer experience, and business agility, while also addressing challenges related to implementation and management. The findings provide insights into how leveraging EDA can drive innovation and competitiveness in the digital economy, offering a roadmap for organizations aiming to harness the full potential of event-driven systems.
