In this hands-on workshop, you’ll learn how to build an image processing workflow using a simple, yet powerful, fully managed service called AWS Step Functions. We will leverage a few additional serverless technologies, including AWS Lambda, Amazon DynamoDB, and Amazon Simple Notification Service (SNS). We will leverage an AWS CloudFormation template to deploy the Step Function template, four Lambda functions, the SNS topic and DynamoDB table. You will configure the workflow to orchestrate them together into a simulated business process that allows uploading a profile picture, checking the photo for uniqueness, generating a thumbnail, and persisting metadata that associates the user with the photo.
This workshop takes about 1 to 2 hours to complete.
