Serverless Voting application in AWS

Heavily inspired on https://github.com/docker/example-voting-app Uses https://github.com/serverless/serverless for deployment

Getting started

Install Serverless

Make sure you have AWS credentials with permissions to CRUD on :

• Cloudformation
• Lambda
• SNS
• Dynamodb

//TODO make this fancier Install node_modules for the 3 apps by running npm install in each of them

Run serverless deploy at the root

Run ng build in result/result-ui and deploy the content of the dist folder somewhere publicly accessible ( S3 would work, but I use netlify)

Architecture

result : a Node.js lambda to display stats from dynamodb

vote : a couple of Node.js lambdas to cast a vote to an SNS topic

worker : a Node.js lambda which consumes event from the SNS topic and stores the vote in DynamoDB
