Using AWS Step Functions to Categorize Uploaded Data

AWS Step Functions is a powerful service that lets you build and orchestrate different AWS services to construct state machines. This can be done with almost any AWS API action, and with little-to-no code. In this lab, we're going to build a Step Functions state machine to process an MP3 call recording, determine the sentiment of the conversation, and take a different action depending on the analysis.
