1. Gemfile

gem 'browserify-rails', '1.5.0' # until fix: https://github.com/browserify-rails/browserify-rails/issues/101
gem 'react-rails'

Browserify-rails allows to use browserify within assets pipeline. React-rails is here only to allow to use #react_component (and thus, prerendering).

Note that jquery-rails can be removed from Gemfile, the npm version of jquery and jquery-ujs will be used instead.

Problem: Normal node cluster based deployments are no longer supported in cloud.docker.com. New users get Swarm mode by default.

Solution: Deploy a swarm of nodes, and use your image to export it as a service on the nodes.

Prerequisite - You have already push your image as a public repository on to Docker hub using the docker.sh file present here - https://github.com/paulnguyen/cmpe281/tree/master/docker

DISCLAIMER: When running in Swarm mode, docker cloud will create Instances, ELBs, Network Interfaces, Security Groups, VPC etc in your AWS account. Delete them after use or you run the risk of overshooting the Free Tier Usage!

Step 1: Link your cloud.docker to AWS

• Follow the instructions at - https://docs.docker.com/docker-cloud/cloud-swarm/link-aws-swarm/

#MongoDB 3.2.x Replica Sets on AWS EC2
A MongoDB replica set provides a mechanism to allow for a reliable database services. The basic replica set consists of three servers, a primary, a secondary and an arbitrator. The primary and secondary both hold a copy of the data. The arbitrator is normally a low spec server which just monitors the other servers and help with the failover process. In production, there can be more than three servers.

To setup mongo as a replica set on Amazon Web Services EC2 you need to first setup a security group with ssh on port 22 and mongodb on port 27017. You then need to create three servers. Select Ubuntu 14.04 LTS x64 and a micro (or bigger depending on your database size, ideally you should have enough memory to match your database size) instance for the primary and secondary and a nano instance for the arbitrator.

##Adjust the File System on each Server
The operating system by default will update the last access time on a file. In a high data throughput database application

# Installing Java

We need Java in order to have Cassandra running
And we need Cassandra in order to run Kong.

So lets start installing Java 8 (the newest one)

First we add a repository to our build in order to manage the Java 8 package, since that is not normally supported by Ubuntu.
```
