Deploying to Amazon and Engine Yard

We used Amazon RethinkDB and EY Node.js to deploy the app.

• Instructions for deploying RethinkDB from Amazon Marketplace. Remember to set authentication key. Otherwise the database is available publicly e.g.

  r.db('rethinkdb').table('cluster_config').get('auth').update({auth_key: 'mysecrestpassword123'})

• We used Engine Yard for our Node.js server. The application was originally developed for Node.js 5 but we adjusted it to the version 4 which was the latest available on EY. Node version for EY is addd in packages.json

  "engines": {"node": "4.2.1-r1"}
