What are the differences between an API and a Service Bus?

What are the differences between an API and a Service Bus?

An API (Application Programming Interface) allows different software applications to communicate directly, while a Service Bus is a messaging system that facilitates communication between applications through messages.

Can you give me an example of when to use a Service Bus instead of an API?

Sure! Use a Service Bus when you need to decouple services, handle high volumes of messages, or ensure reliable message delivery across distributed systems.

What are the advantages of using an API?

APIs provide direct access to services, are easier to implement for synchronous communication, and often have better performance for real-time interactions.

Are there any scenarios where both can be used together?

Yes, you can use both together; for instance, an API can expose endpoints for real-time data access, while a Service Bus can handle background processing and asynchronous tasks.
