Building Reactive & Resilient Systems: Deep Dive into Event-Driven Architecture

Event-Driven Architecture (EDA) fosters asynchronous, decoupled systems that react to changes in real time, ensuring resilience and scalability. Its fundamental principles—loose coupling, autonomy, and asynchronous workflows—come to life through patterns like Publish/Subscribe, Event Sourcing, and CQRS, which promote clear data lineage and separation of reads from writes. While EDA provides benefits such as real-time responsiveness and fault tolerance, it also brings pitfalls like over-decoupling, complex error handling, and eventual consistency. By following best practices for schema evolution, monitoring, and fault-tolerance, teams can leverage EDA's potential for reactive and scalable systems.
