How does AWS Step Functions work?

With AWS Steps Functions, you can define and operate multiple discrete components as one distributed application quickly with something called a state machine. You can define your application using a visual workflow that AWS Step Functions provides using the AWS Console, the Java API, or AWS CloudFormation templates. The visual console automatically creates the workflow and generates a graph for the individual components, based on the order of execution, which makes designing applications using the visual console very easy. I have illustrated three different diagrams detailing how the AWS Step Functions flow works for a photo processing application.
