In this workshop, you get a fully working mobile game that includes common mobile game features, such as authentication, DLC, gifting, leaderboards, and analytics. However, nothing on the server side is built yet. It’s a time for you to breathe life into the game by using the given AWS Lambda code and other AWS services. To do this, bring your own laptop and at least a basic understanding of several AWS services: Amazon Cognito, AWS Lambda, Amazon API Gateway, Amazon S3, Amazon CloudFront, Amazon DynamoDB, Amazon SNS, Amazon SQS, Amazon Kinesis, and Amazon Mobile Analytics.
