What this card says
Why do we need it?
Pieces must fit: UI, API, compute, data.
What is it?
S3+CloudFront UI → API Gateway → Lambda → DynamoDB.
How to do it
Draw the boxes first; then create table, role, function, API, CDN.
Example
Browser lists notes via GET /notes; never talks to DynamoDB directly.
