What are the differences between message queues and APIs?

Message queues are used for asynchronous communication, while APIs are typically synchronous. Message queues allow for decoupling of services, enabling them to communicate without being directly connected.

Can you give me an example of when to use a message queue?

Sure! If you have a system where you need to process orders and you want to ensure that each order is handled even if the processing service is temporarily down, a message queue would be ideal.

What are the advantages of using an API over a message queue?

APIs are great for real-time communication and are easier to implement for direct requests and responses. They provide a straightforward way to access services.

Are there any scenarios where both can be used together?

Absolutely! You can use APIs for real-time requests and responses while employing message queues for background processing tasks, creating a robust architecture.
