In this tutorial, we understand what is spring cloud stream and its various terms. Using spring cloud stream allows you to focus on business development without spending too much effort on the interaction between the application and the mq.
The Configuration Included Is Minimal And Largely Cosmetic;
In a previous tutorial we had implemented an example to publish message to rabbitmq using spring cloud stream.in this example we will see how to consume message using spring cloud stream.

Microservices vs APIs One Doesnt Always Imply the Other from lightrun.com You are able to create a django application and have basic understanding of how to build apis using the django rest framework. There's this insightful comparison between rest apis and rpc apis in terms of their usability that says: In the architecture, i cannot really decide if the client application should send directly to rabbitmq over ampq or if it should hit a rest api and then the rest api sends it to rabbitmq.
