AWS CDK (Cloud Development Kit) allows you to define cloud infrastructure using familiar programming languages like TypeScript, Python, Java, and C#. It provides high-level constructs that abstract AWS services.

Key Features

• Programming Languages - Use TypeScript, Python, Java, C#, Go
• High-level Constructs - Abstract AWS services into reusable components
• Type Safety - Compile-time checking for infrastructure code
• AWS Integration - Native support for all AWS services
• CDK Patterns - Pre-built patterns for common architectures

Common Use Cases

• AWS Infrastructure - Define AWS resources programmatically
• Microservices - Deploy containerized applications
• Serverless - Build serverless applications with Lambda
• Data Pipelines - Create data processing workflows
• Multi-environment - Deploy to dev, staging, and production

Getting Started

// lib/my-stack.ts
import * as cdk from 'aws-cdk-lib';
import * as s3 from 'aws-cdk-lib/aws-s3';

export class MyStack extends cdk.Stack {
  constructor(scope: Construct, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    // Create an S3 bucket
    new s3.Bucket(this, 'MyBucket', {
      versioned: true,
      removalPolicy: cdk.RemovalPolicy.DESTROY,
    });
  }
}

# Install CDK
npm install -g aws-cdk

# Initialize project
cdk init app --language typescript

# Deploy
cdk deploy

Why Choose AWS CDK?

AWS CDK excels when you need:

• Programming Languages - Use familiar languages for infrastructure
• Type Safety - Catch errors at compile time
• Reusability - Create reusable infrastructure components
• AWS Native - Full support for AWS services
• Developer Experience - Better tooling and IDE support

AWS CDK is ideal for teams that prefer programming languages over configuration files for infrastructure management.
