This is a simple demo of an AWS Step function using Lambda. The entire stack is created using CloudFormation.

This is a demo of a serverless application to automate handling of support tickets in a call center. While we could have one Lambda function call the other, managing all of those connections will become challenging as the call center application becomes more sophisticated. Plus, any change in the flow of the application will require changes in multiple places, and could end up writing the same code over and over again.

This challange can be solved using AWS Step Functions. Step Functions is a serverless orchestration service that lets you easily coordinate multiple Lambda functions into flexible workflows that are easy to debug and change. Step Functions will keep your Lambda functions free of additional logic by triggering and tracking each step of your application for you.
