What is the difference between a service bus and a queue?

A service bus is a messaging infrastructure that allows different applications to communicate, while a queue is a specific type of messaging pattern that stores messages until they are processed.

Can you give me an example of when to use a service bus?

Sure! Use a service bus when you have multiple services that need to communicate asynchronously, like in microservices architecture.

And when would I choose a queue instead?

Choose a queue when you need to decouple message producers from consumers, ensuring that messages are processed in order.

Are there any performance differences between the two?

Yes, service buses can introduce some overhead due to their additional features, while queues are generally more lightweight and faster for simple message passing.
