Event-Driven Design
Event-Driven Design is a software architecture and design pattern where the flow of the program is determined by events such as user actions, sensor outputs, or messages from other programs. It involves components that produce, consume, and react to events, often using an event bus or message broker to decouple producers from consumers. This approach enables asynchronous, scalable, and loosely coupled systems, commonly used in real-time applications, microservices, and distributed systems.
Developers should learn Event-Driven Design when building systems that require high scalability, real-time responsiveness, or loose coupling between components, such as in microservices architectures, IoT applications, or financial trading platforms. It is particularly useful for handling unpredictable workloads, enabling reactive programming, and facilitating integration between disparate systems by allowing components to communicate without direct dependencies.
