Two things missing from the Step Functions portion of the article:

* Step Functions module in the AWS CDK: https://docs.aws.amazon.com/cdk/api/latest/docs/aws-stepfunc...

* Step Functions Data Science SDK (python): https://aws-step-functions-data-science-sdk.readthedocs.io/e...

There is first class support for defining Step Functions using real programming languages (although it does compile down to the states language dls before deployment)
