Cloud and Microsoft Azure

Microsoft Azure is a cloud computing platform and infrastructure, created by Microsoft, for building, deploying and managing applications and services through a global network of Microsoft-managed and Microsoft partner hosted datacenters.

Azure Linux VM creation for Node-RED

This link shows you how to use the Azure portal to create a Linux Virtual Machine quickly. The only requirements are an Azure account and SSH public and private key files.

Create a Linux VM on Azure using the Portal
https://azure.microsoft.com/en-us/documentation/articles/virtual-machines-linux-quick-create-portal/

1. Visit Azure portal : https://portal.azure.com
2. Create Resource Group as resource container
   • click top left Resource Group -> click Add -> type Resource group name, and Resource group location set Japan West -> click Create
3. Create VM
   • New -> Compute -> Ubuntu Server 16.04 LTS -> click Create
   • Basics window -> Type Name -> type User Name -> change Authencatetion type to Password -> type Password -> change Resource Group to just created resource group -> change Location to Japan West -> click OK
   • Size window -> select DS1_V2 standard size
   • Settings window -> all default click OK
   • Summary windows -> click OK
4. Access on VM by SSH

SSH key creation (Option)

With an SSH keypair you can create Virtual Machines on Azure that default to using SSH keys for authentication, eliminating the need for passwords to log in.

Reset SSH access (Option)

Manage users, SSH, and check or repair disks on Azure Linux VMs using the VMAccess Extension

Install Node-RED

Node-RED is a tool for wiring together hardware devices, APIs and online services in new and interesting ways.
http://nodered.org/

Node-red is based on node.js -> install node.js first.
https://nodejs.org/en/download/

Install node-red by following command:
sudo npm install -g --unsafe-perm node-red

// Ubuntu distro. - with Aptitude package manager one can install the package nodejs and npm  
sudo apt-get update  
sudo apt-get install nodejs  
sudo apt-get install npm  

// install node-red  
sudo npm install -g --unsafe-perm node-red  

By default, all VM inbound port is blocked, except SSH(port 22). To open another VM inbound port(ex. HTTP 80 port, Node-red 1880 port), process in Azure Portal "Network Security Group".

IoT Mission

Build your own real-world IoT solution to receive data from device to IoT cloud data storage in 60 min.

• Simulated IoT device
• Send JSON data to Azure IoT hub
• Process realtime IoT data in Stream Analytics
• Store JSON data in Azure blob storage

common hands-on, deploy Azure services for IoT

1. Log on to Azure Portal - https://portal.azure.com/
2. Click new - type "resource group" - create - type name and change location to "Japan West"
3. Click new - internet of things - IoT hub click - type name - change Resource group to just created - click create button
4. Click new - internet of things - Stream analytics Job - type job name and change Resource group to just created - click create button
5. Click new - sStorage - Storage account - type name - change Replication to "Locally-redundant storage(LRS)" and change Resource group to just created - click create button
6. click IoT Hub - "Shared access policy" - iothubowner - copy "connection string primary key". This is used in your app as connectionstring value.

You can choice your prefer language between node.js and C# to simulate IoT device

node.js hands-on coding

// Fork and clone https://github.com/CloudBreadPaPa/kaist-cs459 repository.  
// Open kaist-cs459\node\createdeviceidentity folder CreateDeviceIdentity.js file  
// Change below connection string code value as yours  
...  
var connectionString = 'HostName=something.azure-devices.net;SharedAccessKeyName=iothubowner;SharedAccessKey=somgthing';  
...  
device.deviceId = 'kaist-device-00';  
...  

//Execute CreateDeviceIdentity.js app to generate device key  
node CreateDeviceIdentity.js  

// Open kaist-cs459\node\simulateddevice folder SimulatedDevice.js file  
// Change below code  
...  
var connectionString = 'HostName=something.azure-devices.net;DeviceId=kaist-device-00;SharedAccessKey=generated-device-key';  
...  

//Execute SimulatedDevice.js app send IoT message to IoT Hub  
node SimulatedDevice.js  

C# hands-on coding

// Fork and clone https://github.com/CloudBreadPaPa/kaist-cs459 repository.  
// open kaist-cs459\cs\cs459-iot folder, cs459-iot.sln Visual Studio solution file  
// CreateDeviceIdentity project - Program.cs file  
// Change below code to your connection string  
...  
static string connectionString = "HostName=something.azure-devices.net;SharedAccessKeyName=iothubowner;SharedAccessKey=something";  
...  
string deviceId = "dw-kaist-device00";  
...  

Execute project and generate device Key

// open SimulatedDevice project - Program.cs file  
// change below code  
...  
static string iotHubUri = "something.azure-devices.net";  
static string deviceKey = "generated-device-key";  
...  
deviceClient = DeviceClient.Create(iotHubUri, new DeviceAuthenticationWithRegistrySymmetricKey("dw-kaist-device00", deviceKey));  
...  

execute project to simulate IoT device.

common hands-on, set "Stream Analytics Job"

Go to Azure Portal - Reource Group - click your scream analytics - inputs - add - type name "input" and select "IoT Hub".
Azure automatically populate IoT hub information and set it as input - click save
Click outputs - add - type name "output" - Change Sink to "Blob storage" - select Storage account just created - click "create" button
In Stream Analytics - overview - click Start button on the top - start it now
Check output blob file.
