CDK-cloud infrastructure with code

Introduction to AWS Cloud Development Kit (CDK)

AWS Cloud Development Kit (CDK) is an open-source software development framework that enables developers to define cloud infrastructure using familiar programming languages like TypeScript, JavaScript, Python, Java, and C#. CDK abstracts AWS CloudFormation, allowing developers to write reusable and testable infrastructure as code. By using high-level constructs called L2 and L3 constructs, CDK simplifies the process of provisioning AWS resources and automates much of the boilerplate code required in traditional CloudFormation templates. For example, consider an application that requires an S3 bucket and a Lambda function. With CDK, you can define these resources programmatically in a TypeScript file: ```typescript import * as cdk from '@aws-cdk/core'; import * as s3 from '@aws-cdk/aws-s3'; import * as lambda from '@aws-cdk/aws-lambda'; class MyStack extends cdk.Stack { constructor(scope: cdk.Construct, id: string, props?: cdk.StackProps) { super(scope, id, props); // Define an S3 bucket const bucket = new s3.Bucket(this, 'MyBucket'); // Define a Lambda function const func = new lambda.Function(this, 'MyFunction', { runtime: lambda.Runtime.NODEJS_14_X, handler: 'index.handler', code: lambda.Code.fromAsset('lambda') }); } } ``` This code is both concise and easy to understand, showcasing how CDK enables the development of cloud applications with minimal configuration.
