What are the differences between event bus and other messaging patterns?

What are the differences between event bus and other messaging patterns?

The event bus pattern allows for decoupled communication between components, while other patterns like message queues focus on point-to-point communication.

Can you explain how event bus improves scalability?

Event bus enhances scalability by allowing multiple subscribers to listen to events without direct dependencies, enabling easier load distribution.

What are some use cases for using an event bus?

Common use cases include microservices communication, real-time data processing, and event-driven architectures.

Are there any drawbacks to using an event bus?

Yes, potential drawbacks include increased complexity in debugging and the risk of event storms if not managed properly.

How does the event bus compare to a message queue?

While both facilitate communication, an event bus is more about broadcasting events to multiple subscribers, whereas a message queue typically ensures messages are processed in order by a single consumer.
