Kotlin + AWS serverless workshop

Architecture

In this workshop we are going to build a simple event driven application that processes events on event bridge with AWS Lambda; saves the result in DynamoDB NoSQL database; and exposes the data via GraphQL through AWS AppSync:

At the end of the workshop you should have an understanding of how to build, configure and deploy an AWS serverless application in Kotlin using CDK in Kotlin.
