Using DynamoDB effectively requires a good understanding of its unique data modeling principles, which can be different from traditional relational databases. This learning curve can be steep for developers who are new to NoSQL databases.
it is only as good as the user/admin who knows how to make the most out of this software. there is a deep learning process involved without which one could be flying blind and exposing otherwise sensitive data to the public... S3 is an enterprise-grade service pretending to be beginner-friendly.
you need to have general knowledge of AWS services and their strong and weak points to be able to choose the optimal one for the task, 2) you need to have good knowledge of the chosen service (like DynamoDB or Step Functions) to be able to use it optimally; being mediocre at it is often not enough
