AWS CDK

ELI5 — The Vibe Check

CDK lets you define your cloud infrastructure using actual programming languages instead of YAML. It's like the difference between writing a recipe in English vs. pointing and grunting. You get loops, conditionals, type safety, and autocomplete — all the things that make YAML developers weep with jealousy.

Real Talk

AWS Cloud Development Kit (CDK) is an open-source framework that lets you define cloud infrastructure using familiar programming languages like TypeScript, Python, Java, or Go. It synthesizes your code into CloudFormation templates, providing higher-level abstractions (constructs) that bundle best practices and sensible defaults.

Show Me The Code

import * as cdk from 'aws-cdk-lib';
import * as lambda from 'aws-cdk-lib/aws-lambda';

const fn = new lambda.Function(this, 'MyFunction', {
  runtime: lambda.Runtime.NODEJS_20_X,
  handler: 'index.handler',
  code: lambda.Code.fromAsset('lambda'),
});

When You'll Hear This

"We migrated from raw CloudFormation to CDK and our infra code is actually readable now." / "CDK constructs handle all the IAM boilerplate for you."
