Description

AWS Step Functions is a web service that enables you to coordinate the components of distributed applications and microservices using visual workflows.

Step Functions manage the operations and underlying infrastructure for you to ensure your application is available at any scale.

In this lab, you will see what AWS Step Functions are and what types of problems this service is best suited to solve. By the end of this lab, you will have created a solution that combines Lambda and Step Functions for a fictitious gaming application.
