What are some use cases for event-driven architecture?

Event-driven architecture (EDA) is great for applications that require real-time processing. Common use cases include IoT systems, financial services for transaction processing, and e-commerce platforms for managing inventory and orders.

Can you explain how EDA works in IoT systems?

In IoT systems, EDA allows devices to send events to a central system when certain conditions are met, enabling real-time data processing and response. For example, a smart thermostat can send temperature readings to a cloud service, which can then trigger actions like adjusting the heating.

What are the benefits of using EDA over traditional architectures?

EDA offers improved scalability, flexibility, and responsiveness. It allows systems to react to events as they happen, rather than relying on scheduled polling, which can lead to delays.

Are there any challenges associated with implementing EDA?

Yes, challenges include managing event schema evolution, ensuring message delivery, and handling event ordering. Proper design and tooling can help mitigate these issues.
