• High scale data ingestion via Event Hub.

• High scale stream processing via Stream Analytics (or HDInsight /Storm)

• Storage for cold-path analytics

• Processing for hot-path analytics

Start the pipeline with Telemetry

Event HubStream Analytics

SQL Blob

• Real-time analytics for Internet of Things solutions• Stream millions of events per second• Mission critical reliability, performance and predictable

results• Rapid development with familiar SQL-based language

Event Hubs and Stream Analytics• Cloud-scale telemetry ingestion from websites, apps,

and devices• Compatible with more than a million publishers

supporting HTTP, AMQP and MQTT• Ingress millions of events per second • SAS based security, with unique token per publisher• Configurable data retention (1-30 days)• Low latency (<10 ms for volatile data)• Pluggable with other cloud services like Stream Analytics

Access Control Policies

Devices

• Simple MCU-based boards• Arduino Uno, Due ...

• Advanced (MCU-based) boards with networking• Tessel• Arduino Yun ...

• Full computing platform in embedded form factor• Raspberry Pi• BeagleBone Black …

• Back to simple MCU-based boards• Using a more powerful device as a field gateway

Different types of Devices

Simple MCU boards: Arduino

EthernetClient client;const char *server = "arduinouno.azure-mobile.net";if (client.connect(server, 80)) { sprintf(buffer, "POST /tables/%s HTTP/1.1", table_name); client.println(buffer); sprintf(buffer, "Host: %s", server); sprintf(buffer, "X-ZUMO-APPLICATION: %s", ams_key); client.println("Content-Type: application/json"); sprintf(buffer, "{\"value\": %d}", value); client.print("Content-Length: "); client.println(strlen(buffer)); client.println(); client.println(buffer);

Sending data to Azure Mobile Services

Demo

• Arduino Uno• Ethernet Shield• Photoresistor• Analog sound sensor• Send to Mobile Services• Plot using Highcharts

and OData endpoint

Advanced board: Arduino Yun

Process proc;void send_request(int value){ proc.begin("curl"); proc.addParameter("-k"); proc.addParameter("-X"); proc.addParameter("POST"); proc.addParameter("-H"); proc.addParameter("Content-Type:application/json"); proc.addParameter("-H"); proc.addParameter("Authorization:" + sas_key); proc.addParameter("-d"); proc.addParameter("{\"value\":" + String(value) + "}"); proc.addParameter("https://" + server + "/" + hub_name + \ "/publishers/" + device_name + "/messages"); proc.run();

Sending HTTPS data to Event Hubs using cURL

Demo

• Arduino Yun• Built-in Wi-Fi• Sparkfun Weather

Shield• Send telemetry data to

Event Hubs• Temperature• Humidity• Pressure• Light

• Over HTTPS using cURL

Advanced board: Tessel

Sending data to Event Hubs in JavaScript/Nodevar options = {

hostname: namespace + '.servicebus.windows.net', port: 443, path: '/' + hubname + '/publishers/' + devicename + '/messages', method: 'POST', headers: { 'Authorization': my_sas, 'Content-Length': payload.length, 'Content-Type': 'application/atom+xml;type=entry;charset=utf-8' } };   var req = https.request(options, function(res) { res.on('data', function(d) { process.stdout.write(d); }); });

Generating a SAS key

http://eventhubssasgenerator.azurewebsites.net

/

function create_sas_token(uri, key_name, key) { // Token expires in one hour var expiry = moment().add(1, 'hours').unix();   var string_to_sign = encodeURIComponent(uri) + '\n' + expiry; var hmac = crypto.createHmac('sha256', key); hmac.update(string_to_sign); var signature = hmac.digest('base64'); var token = 'SharedAccessSignature sr=' + \encodeURIComponent(uri) + '&sig=' + \encodeURIComponent(signature) + '&se=' \+ expiry + '&skn=' + key_name;   return token; }

Uploading picture directly to Azure Storagefunction upload_picture(name, image) {

var options = { hostname: blob_host, port: 443, path: '/' + blob_container + '/' + name + blob_sas, method: 'PUT', headers: { 'Content-Length' : image.length, 'x-ms-blob-type' : 'BlockBlob', 'Content-Type' : 'image/jpeg' } };   var req = https.request(options, function(res) { res.on('data', function(d) { process.stdout.write(d); }); });

Demo: Face Detection with Project Oxford• Tessel board• Camera module• Takes a picture every

5 sec• Upload the picture to

Azure Blob Storage• Query Project Oxford

Face API, send Blob link

• Get a response back with face attributes like gender and age!

AMQP over SSL: Proton bindings in Pythonimport sys import commands from proton import *   address = "amqps://send:xxxx@demohub.servicebus.windows.net/yun";   # Create Proton objects messenger = Messenger()   # Create AMQP message message = Message()   message.body = sys.argv[1]   message.address = address messenger.put(message) messenger.send()

Sending to Azure from Windows 10address = new Address(sbNamespace, 5671, keyName, keyValue);connection = new Connection(address);session = new Session(connection);sendLink = new SenderLink( session, "send-link:" + entity, entity);var messageValue = Encoding.UTF8.GetBytes(data);// AMQP supports 3 types of body, here we use Data.var message = new Message() { BodySection = \ new Data() { Binary = messageValue } };sendLink.Send(message);
