This page is a running piece of AWS infrastructure, not a mockup of one. Everything below — the CDN, the database, the function answering the counter — is live right now.

Serving over CloudFront

Deployed via AWS CDK

ARCHITECTURE — live traffic + monitoring path

Static content is edge-cached through CloudFront. The visitor counter hits a separate serverless path — API Gateway → Lambda → DynamoDB. A CloudWatch alarm watches the Lambda's error rate and emails an alert via SNS if anything fails.

STACK

Amazon S3Origin storage for site files

CloudFrontCDN + HTTPS, OAC-secured origin

API Gateway (HTTP API)Public endpoint for the counter

Lambda (Python 3.12)Self-initializing counter logic

DynamoDBOn-demand, single-item table

CloudWatch + SNSAlarm on Lambda errors, emailed on trigger

AWS CDK (Python)Whole stack, one command

GitHub ActionsTests + cdk synth on every push

Every load of this page calls the live API above and increments a real row in DynamoDB. No mock data.
