When should I choose Pub/Sub over Event Bus?

What are the main differences between Pub/Sub and Event Bus?

Pub/Sub is a messaging pattern where publishers send messages to subscribers without knowing who they are, while Event Bus is a more centralized system that allows for event-driven communication between components.

In what scenarios would I prefer using Pub/Sub?

You might prefer Pub/Sub when you need scalability, loose coupling, and asynchronous communication, especially in microservices architectures.

Are there any downsides to using Pub/Sub?

Yes, some downsides include potential message delivery delays, complexity in managing subscriptions, and challenges in ensuring message order.

Can you give me an example of a use case for Event Bus?

Sure! An Event Bus is great for applications where components need to communicate in real-time, like a chat application where messages need to be delivered instantly to multiple users.
