Event Driven architecture is a design paradigm that emphasizes the production, detection, consumption, and reaction to events. An event can be defined as a significant change in the state of a system, and this approach is particularly useful for building scalable and decoupled systems. By adopting an Event Driven approach, systems can achieve greater responsiveness and flexibility, as components can operate independently and asynchronously, reacting to changes as they occur.
This method is especially relevant in today's microservices and cloud-native environments, where systems benefit from being loosely coupled and highly responsive. In the methods-and-patterns quadrant, Event Driven is a critical pattern that supports modern software architecture needs, enabling systems to handle complex workflows and data processing tasks efficiently. Its placement in the "adopt" ring indicates that it is a mature approach that organizations should incorporate into their architecture to enhance agility and scalability.
