Now that our initial stack has been deployed it's time to dig into AWS Console to see what exactly did we deploy. Cloud Development Kit is built on top of CloudFormation which is an AWS service that allows you to describe a stack in AWS using a static file (either YAML or JSON). In essence - it's going to convert our code written in TypeScript, to JavaScript, which will be then converted to CloudFormation and CloudFormation will be used to deploy our infrastructure. Sounds complicated, right? Luckily CDK abstracts a lot of things away from us, so we get to focus on solving our problems instead of writing YAML by hand. In this lesson we're going to learn how to review an AWS CDK stack deployment in CloudFormation console.
