The benefits of event-driven architecture derive from how systems and components are loosely coupled, which can facilitate independent development and deployment of systems, improved scaling and fault tolerance, and integration with external systems, especially in comparison to monolithic architectures.

Event-driven architecture (EDA) promotes loose coupling between components of a system, leading to greater agility. Microservices can scale independently, fail without impacting other services, and reduce the complexity of workflows. Events can be flexibly routed, buffered, and logged for auditing purposes.

Why use event-driven architecture? The value of knowing about a given event, and being able to react to it, degrades over time. The more quickly you can get information about events where they need to be, the more effectively your business can react to opportunities to delight a customer, shift production, and re-allocate resources.

Organizations can add event-driven architecture to their systems and applications to improve the scalability and responsiveness of applications and access to the data and context needed for better business decisions.

Event-driven architecture allows systems to react to real-world events and makes communication asynchronous. This improves operations and makes them more agile and scalable so things can keep running smoothly no matter how big or complex they get.
