1. Create change set:

	var AWS = require('aws-sdk');
	AWS.config.update({region: 'us-east-2'});
	var cloudformation = new AWS.CloudFormation();

	var params = {
		ChangeSetName: "blueV1",
		ChangeSetType: "CREATE"
		StackName: "myNewApp",
		TemplateURL: "https://s3.amazonaws.com/cloudformations-014066636401/cloudformations/stacks/blue.yaml",
		Capabilities: ["CAPABILITY_NAMED_IAM"]
	};
	cloudformation.createChangeSet(params, function(err, data) {
		if (err) console.log(err, err.stack); // an error occurred
		else     console.log(data);           // successful response
	});

2. View change set:

	var AWS = require('aws-sdk');
	AWS.config.update({region: 'us-east-2'});
	var cloudformation = new AWS.CloudFormation();

	var params = {
		ChangeSetName: "blueV1",
		StackName: "myNewApp"
	};
	cloudformation.describeChangeSet(params, function(err, data) {
		if (err) console.log(err, err.stack); // an error occurred
		else     console.log(data);           // successful response
	});

	If you review the request from the AWS Cloudformations console, the "myNewApp" 
	stack will remain in a "Reviewing" state until the changes are implemented by 
	the execute-change-set command.

3. Execute change set:

	var AWS = require('aws-sdk');
	AWS.config.update({region: 'us-east-2'});
	var cloudformation = new AWS.CloudFormation();

	var params = {
		ChangeSetName: "blueV1",
		StackName: "myNewApp"
	};
	cloudformation.executeChangeSet(params, function(err, data) {
		if (err) console.log(err, err.stack); // an error occurred
		else     console.log(data);           // successful response
	});

1. Update change set:

	var AWS = require('aws-sdk');
	AWS.config.update({region: 'us-east-2'});
	var cloudformation = new AWS.CloudFormation();

	var params = {
		ChangeSetName: "blueV2",
		ChangeSetType: "UPDATE"
		StackName: "myNewApp",
		TemplateURL: "https://s3.amazonaws.com/cloudformations-014066636401/cloudformations/stacks/blue.yaml",
		Capabilities: ["CAPABILITY_NAMED_IAM"]
	};
	cloudformation.createChangeSet(params, function(err, data) {
		if (err) console.log(err, err.stack); // an error occurred
		else     console.log(data);           // successful response
	});

Independent cloudformation templates that deploy a single AWS service

Repo location: ./resorces/*

Example:

	./resources/sqs.yaml

	AWSTemplateFormatVersion: '2010-09-09'
	Description: sqs
	Resources:
	  sqs:
	    Type: "AWS::SQS::Queue"
	    
	Outputs:
	  sqsArn:
	    Value: !GetAtt sqs.Arn
	  sqsName:
	    Value: !GetAtt sqs.QueueName

Parameters of the Resource Templates that are included from any external s3 bucket. 
These could be defined by a developer or security team..etc and sourced during deployment. 

Repo location: ./transforms/*

Example:

	./transforms/lambda.yaml

	MemorySize: 1024
	ZipFile: console.log("hello world and goodbye")
	Timeout: 25
	Mode: Active

A grouping of Resource Templates working together for a single application. 
Upon a Stack update, an changes within any of the independant Resource Templates or external Transform files
are applied to the overall Stack(s).

Repo location ./stacks/*
