What are some use cases for an event bus?

Event buses are commonly used for decoupling microservices, enabling real-time data processing, and handling asynchronous communication.

Can you give me an example of how an event bus works in a microservices architecture?

Sure! In a microservices architecture, an event bus can facilitate communication between services. For instance, when a user places an order, the order service can publish an event to the bus, which other services like inventory and shipping can subscribe to and react accordingly.

What are the benefits of using an event bus?

The benefits include improved scalability, better fault tolerance, and enhanced flexibility in adding or modifying services without affecting others.

Are there any downsides to using an event bus?

Yes, potential downsides include increased complexity in managing events and the need for robust error handling to deal with message failures.
