In this tutorial, you'll create a simple serverless web application that enables users to request unicorn rides from the Wild Rydes fleet. The application will present users with an HTML based user interface for indicating the location where they would like to be picked up and will interface on the backend with a RESTful web service to submit the request and dispatch a nearby unicorn. The application will also provide facilities for users to register with the service and log in before requesting rides.
The application architecture uses AWS Lambda, Amazon API Gateway, Amazon S3, Amazon DynamoDB, and Amazon Cognito as pictured below:


Static Web Hosting
Amazon S3 hosts static web resources including HTML, CSS, JavaScript, and image files which are loaded in the user's browser.

User Management
Amazon Cognito provides user management and authentication functions to secure the backend API.

Serverless Backend
Amazon DynamoDB provides a persistence layer where data can be stored by the API's Lambda function.

RESTful API
JavaScript executed in the browser sends and receives data from a public backend API built using Lambda and API Gateway.
