Build a Serverless API with AWS Lambda and API Gateway

Expose a small HTTP API with no servers to manage: a Lambda function behind API Gateway, deployed from the CLI.

By CareerByteCode
Problem statement

You need a small HTTP endpoint (for a form, a webhook, or a lookup) but do not want to run or pay for an always-on server.

Why we need this realtime usecase

Lambda plus API Gateway scales to zero and to thousands automatically; you pay per request, and there is no OS to patch.

When we need this realtime usecase

Use this for low-to-spiky-traffic endpoints, webhooks, and glue APIs where a full service is overkill.

Prerequisites for the lab

An AWS account, the AWS CLI, and a runtime you know (this lab uses Node.js). Basic JSON and HTTP.
