Hands-On Mini Lab

Serverless API Design Lab

Design-only lab unless you deploy. Deploying API Gateway and Lambda can create small charges.

Goal

Reinforce API Gateway, Lambda, IAM roles, Auth, Logging, Retries through a small, inspectable activity.

Concepts Reinforced

  • API Gateway
  • Lambda
  • IAM roles
  • Auth
  • Logging
  • Retries

Prerequisites

  • No AWS account required for design-only path

Estimated Cost

Exact Steps

  1. Draw a request path from client to API Gateway to Lambda to DynamoDB.
  2. Mark authentication, authorization, input validation, timeout, retry, and logging points.
  3. Decide which failures should return 4xx, which should retry, and which should go to a DLQ or alarm.
  4. Map each permission the Lambda execution role needs.
Conceptual API path
Client -> API Gateway authorizer -> Lambda validation -> DynamoDB conditional write -> CloudWatch Logs/metrics

Verification

  • Every data access is tied to an IAM permission.
  • Every failure has a response or retry path.
  • Logs avoid sensitive data.

Cleanup Steps

  • No cleanup for design-only path. Delete any deployed API, Lambda, role, logs, and table if you build it.
