Aim of the Demo is to bring to light performance considerations when designing a Scalable MEAN Applicaiton

App will be deployed on Azure using ARM

initial code base taken from

https://github.com/Azure/azure-quickstart-templates/tree/master/node-mongodb-high-availability and also ARM template for Centos VM Cluster template

initial copy of chirp app taken from https://github.com/MicrosoftLearning/chirp/

Demo 1 using front end NODEJS cluster and Single mongoDB Replica Set

Show effect of mongodb configurations, including write concern on the performance

Steps to get things started

Execute following from Powershell

1 you will be prompted for your azure accound credentials after this command

powershell

Add-AzureAccount

CLI

azure login

2

powershell

Switch-AzureMode AzureResourceManager

CLI

azure config mode arm

3 Create ResourceGroup and Storage Account (Optional)

powershell

New-AzureResourceGroup -Name 1resgrp -Location "West US" New-AzureStorageAccount -Name 1stoacc -Location "WEST US" -AccountType Standard_LRS -ResourceGroupName 1resgrp

CLI

azure group create 1resgrp westus azure storage account create -l westus -g 1resgrp --type LRS 1stoacc

4 You will be promted for username, password,

storage account, frontendstorage account, redis host, redis key, new relic key and Dns name for node cluster .

The username and password will have root access on the Ubuntu VMs as well as admin acess on the mongodb replica set

New-AzureResourceGroupDeployment -Name mongo-deploy-2 -ResourceGroupName 5-res-grp -TemplateUri https://raw.githubusercontent.com/maninderjit/MEAN-demo/master/Centos-nojejs-nodes-mongodb-one-replica-set/azuredeploy.json -Verbose

To Debug you can use following

Get-AzureResourceGroupLog -ResourceGroup 1resgrp -Status Failed -DetailedOutput
