Introduction

Goals

Introduce the serverless workshop: create Lambda (Node.js/Python), accept input parameters, integrate API Gateway, and deploy an in-app purchase suggestion API. Emphasize fast delivery with Lambda without managing servers.

Architecture at a glance

  • Lambda receives events, processes logic, and returns JSON.
  • API Gateway is the REST front door mapping methods to Lambda.
  • Optional: custom domain/stage for multiple environments.

Expected outcomes

  • Two Hello World functions (Node.js/Python) with parameters.
  • One REST endpoint (GET/POST) via API Gateway.
  • One business-logic function (purchase suggestions) returning JSON.

Timing & structure

  • Part 1: Lambda basics, testing in the console.
  • Part 2: API Gateway, input mapping, testing.
  • Part 3: In-app purchase exercise, clean up resources.
