The serverless offerings of AWS (or any other public cloud provider today) are getting more and more popular. One of the biggest reasons is of course not needing to think about infra (server provisioning and so on). The other reasons include the offerings themselves, which at times fit well into the technical need for finding solutions to the given problems. But on the other side, it remains a challenge to know the offerings in detail to leverage them properly. There could be always some new feature hidden deep inside the bulk of the documentation.
Background

We can go serverless in the cloud in various ways, but the initial solutioning was decided to leverage the Step Function and Lambda Function along with some more integration offerings from AWS, namely SNS, SQS, and EventBridge.
