Brief Tutorial on AWS Step Functions

Watch Walkthrough on O'Reilly

Overview

The overall idea is to chain AWS Lambda functions together where the input of one feeds into another function.

You can invoke the step functions or individual lambdas via the AWS CLI

List AWS Step Functions

aws stepfunctions list-state-machines

Execute Step Functions

aws stepfunctions start-execution --state-machine-arn "arn:aws:states:us-east-1:561744971673:stateMachine:Demo-Customer-Service-System" --input "{\"phrase\" : \"Today is a beautiful day\"}"

This invokes the step function remotely which is a powerful way to do serverless Data Engineering.
