What are the differences between publish-subscribe and other architectures?

Publish-subscribe architecture allows for decoupled communication between components, unlike traditional request-response models.

Can you explain how publish-subscribe improves scalability?

Sure! In publish-subscribe, publishers and subscribers are independent, allowing systems to scale by adding more subscribers without affecting publishers.

What are some real-world applications of publish-subscribe architecture?

Common applications include messaging systems, event-driven architectures, and real-time data feeds in financial services.

How does it compare to message queue systems?

While both facilitate communication, message queues are typically point-to-point, whereas publish-subscribe allows multiple subscribers to receive messages from a single publisher.

Are there any downsides to using publish-subscribe?

Yes, potential downsides include increased complexity in managing subscriptions and the possibility of message loss if not handled properly.
