A minimal app architecture on AWS: a serverless stack — what every service does and how to read the diagram (part 1/2)
We take a reference serverless app diagram on AWS apart layer by layer: Route 53, CloudFront, S3, API Gateway, Lambda, DynamoDB, SQS, Cognito, CloudWatch — what each service does and why it hurts without it. A minimal SAM template rebuilds a copy of the diagram in one evening.
