Event-Driven Architecture in .NET Core Using RabbitMQ

Event-Driven Architecture (EDA) enables building scalable, resilient, and loosely coupled applications through asynchronous communication. RabbitMQ serves as a message broker implementing AMQP, providing reliable message delivery, flexible routing, and easy .NET integration. The pattern involves producers publishing events to exchanges, which route messages to queues where consumers process them asynchronously. Best practices include using meaningful event names, making events immutable, handling failures with retries and dead-letter queues, avoiding tight coupling between services, and using JSON for payloads. While EDA offers advantages like scalability and fault isolation, challenges include debugging complexity and eventual consistency.
