Summary

In this workshop, you’ve learned about:

  • AWS CDK: The IaC solution from AWS that model application infrastructure using programming languages (TypeScript, Python, Java, and .NET).

  • The main concepts of CDK: app, stack, construct.

  • The structure of an CDK app: bin, lib directories…

  • AWS Toolkit CLI’s commands:

    • cdk init
    • cdk bootstrap
    • cdk synth
    • cdk diff
    • cdk deploy
    • cdk destroy

  • Using CDK with TypeScript to deploy:

    • A hello world Lambda function.
    • A DynamoDB table.
    • Grant permission to interact with DynamoDB table for a Lambda function.
    • Lambda functions for CRUD operations for users.
    • A REST API Gateway and integrate with Lambda functions.

Now you have the infrastructure for the whole workshop as code (it’s infrastructure as code), you can quickly re-deploy it to your AWS account.

  • Try running cdk diff and cdk deploy to see the power of CDK (and infrastructure as code).
