Serverless URL Shortener

A real-world serverless application built with AWS to generate and manage custom short URLs.

Project Overview

• Create short URLs from long links using a web form
• Redirect users to the original URL via a clean custom domain
• Modern UX: "Go to" button and clipboard copy support

Architecture Summary

• Frontend: Static HTML site hosted on Amazon S3 + CloudFront with HTTPS
• Backend: Two AWS Lambda functions — one for generating links, one for redirects
• API Gateway: One HTTP API with two routes mapped to Lambdas:
• POST /create → creates short links
• ANY /{proxy+} → handles redirection
• DynamoDB: Stores mapping between shortCode and long URLs
• Custom domain: go.stevedel.com configured via Route 53 + ACM

AWS Services Used

• AWS Lambda – Backend logic for create/redirect
• Amazon API Gateway – HTTP API with custom domain
• Amazon DynamoDB – Key-value store for URL mappings
• AWS Certificate Manager (ACM) – TLS cert for CloudFront and custom domain
• Amazon Route 53 – DNS routing for go.stevedel.com
• Amazon S3 – Hosts the frontend site
• Amazon CloudFront – Delivers static site over HTTPS
• AWS IAM – Secures GitHub Actions deployments
• GitHub Actions – CI/CD pipeline for code + infra updates
