AWS CDK Lambda and API Gateway Setup

Overview

This lab enables learners to deploy and manage serverless applications using the AWS Cloud Development Kit (CDK) with TypeScript. You will define a Lambda function, expose it via API Gateway, test the API endpoint, and clean up resources. This hands-on experience provides valuable insights into Infrastructure as Code (IaC) practices and serverless architecture on AWS.

Inside this Lab

Participants will learn how to:

Configure the AWS CLI for authentication and interaction with AWS services.
Initialize an AWS CDK project, laying the foundation for Infrastructure as Code deployment.
Create a custom AWS Lambda function to handle serverless compute tasks.
Define and connect Lambda functions with an API Gateway in the CDK stack.
Deploy the defined infrastructure to AWS with cdk deploy.
Test the Lambda-backed API using tools like curl and verify its functionality.
Remove deployed resources using cdk destroy to prevent unnecessary costs.

Key Takeaways

Understand the core concepts of AWS CDK, an IaC tool that simplifies cloud resource management.
Gain practical experience with AWS Lambda and API Gateway to build serverless applications.
Learn to automate resource cleanup to avoid billable AWS charges post-project completion.
Develop confidence in writing TypeScript-based infrastructure definitions for scalable and reusable deployments.

Difficulty Level: Medium

This lab is categorized as medium difficulty, making it ideal for participants with basic knowledge of AWS concepts and programming experience in TypeScript.

Technologies Covered

This lab focuses on:

AWS Lambda: Serverless compute for running code without managing servers.
API Gateway: Managed service to expose RESTful APIs for Lambda functions.
