Serverless URL Shortener on AWS
Short links served by Lambda and DynamoDB, with per-link click stats
1-2 weeks build
Overview
A link shortener with no server to patch. API Gateway routes create and redirect calls to Python Lambda functions, DynamoDB stores each code with a conditional write so two links never collide, and every redirect logs a click that is rolled up into daily counts per link. The whole stack is one SAM template and sits comfortably inside the AWS free-tier allowances.
What makes it stand up
- 01Collision-safe short codes using DynamoDB conditional writes
- 02Redirects answered by Lambda behind an HTTP API
- 03Click analytics by day, referrer and country per link
- 04Whole stack deployed and torn down from one SAM template
- 05Runs within AWS free-tier limits for a student demo
