@Lawrence Wong Thanks for the question.
We have created an end to end HDInsight workshop for our customers. The git hub repo can be accessed here. The content has step by step guide for using HDInsight and Azure Machine Learning on the same use-case and dataset. It could be used to deliver a guided introductory workshop to customers.
