Building and Debugging Serverless Applications with Cloud9

Build a simple Lambda Function that sits behind an API gateway endpoint, learn how to use the Cloud9 IDE to Build, Debug and Deploy this Function.

Introduction

This lab aims to show users how easy it is to create, build, test and deploy a Lambda function behind an API Gateway Endpoint using Cloud9. The function will initially run locally in the Cloud9 environment, where we will debug it to gain an understanding, before changing it to suit our needs, and finally deploying it into AWS.

1. Goto to AWS Console
   • Goto Cloud9
   • Go to Account Environments.
