# Serverless Web Application with React Frontend with .NET

## Step-by-Step Walkthrough
--------

**Overview and Services Used:**

This walk-through provides a .NET Core serverless web application with a React App on the frontend hosted using Lambda and Api Gateway through the Serverless Appliation Model(SAM). The application provides a basic web application using Cognito to access AWS resources such as DynamoDb to retrieve songs stored in Amazon DynamoDB and hit a third party lyric API for a musical quiz. It also has X-ray installed for application debugging. In addition it uses the SAM CloudFormation template for deploying the application components to AWS.
