Mini Tutorial: Setup AWS Lambda + ACM + API Gateway with AWS Cloud Development Kit

This project is a tutorial and example implementation for deploying a functional public API on AWS using the Cloud Development Kit (CDK). It demonstrates how to set up an API Gateway endpoint with a custom domain via ACM, which receives HTML form POST requests (e.g., a contact form) and relays the data to the Pushover notification service via a Lambda function.

Key Features

• Custom Domain HTTPS API — Configures API Gateway with AWS Certificate Manager for secure, personalized endpoints (e.g., https://api.yourdomain.com).
• Form Data Processing — Lambda function handles JSON payloads from POST requests and validates input.
• Pushover Integration — Automatically sends notifications to Pushover with form-submitted data.
• Infrastructure as Code — Uses AWS CDK to define and provision all AWS resources (Lambda, API Gateway, ACM) in a repeatable way.
• Automated Deployment — Includes a Makefile for bootstrapping, deploying, and destroying the stack with minimal manual steps.

Philosophy

The project emphasizes practical, real-world migration from Terraform to AWS CDK, showcasing how to automate cloud infrastructure with a focus on simplicity and integration with third-party services.
