4. What is IoT?
The Internet of things (IoT) is the network of physical
devices, vehicles, home appliances, and other items
embedded with electronics, software, sensors, actuators,
and network connectivity which enable these objects to
connect and exchange data.
From Wikipedia: https://en.wikipedia.org/wiki/Internet_of_things

5. What is IoT…

6. Device Cloud BigData, ML, AISensor, BLE, NBIoT
microprocessor mips / arm x86 / x64 / unix iaas / paas / saas

7. Device Cloud
● Connectivity: Async, Sync
● Install & Upgrade: Container,
Package
● AI / ML
● Remote Control / Managment
● Data Cache: Queue
● Data Process: Batch, Streaming
● Data Store: Object Store, Data
Query
● BI: Report, Business Integration
● AI / ML

8. 從Google IoT架構看看Google Cloud Platform上的IoT Family
IoT低加
結合serverless
GCP上的BigData系列
當紅的Machine Learning
我才是主角

9. Cloud PubSub
● Deliver event data wherever you need it
● Build multi-cloud and hybrid applications on open
architecture
● Scale responsively and automatically
● Bring reliability and security tools to real-time apps

10. Cloud PubSub
Repo: https://github.com/gcpug-tw/pubsub-example.git
subscription.pull(options, function (err, messages) {
if (err) return callback(err);
// Do something for each message
messages.forEach(handleMessage);
console.log('Pulled %d messages!', messages.length);
// Acknowledge messages
var subscription = pubsub.subscription(subscriptionName);
if(messages && messages.length > 0)
subscription.ack(messages.map(function (message) {
return message.ackId;
}), function (err) {
if (err) {
return callback(err);
}
console.log('Acked %d messages!', messages.length);
return callback(null, messages);
});
});

11. ● Microservices Over Monoliths
● Connect & Extend Cloud Services
● Serverless Economics
● Mobile Ready
● Just Add Code
● Open and Familiar
Cloud Function

12. Cloud Function

13. ● Enterprise Cloud Data Warehouse
● Speed & Scale
● Incredible Pricing
● Security & Reliability
● Partnerships & Integrations
BigQuery

14. var bigqueryClient = bigquery({
projectId: 'grape-spaceship-123',
keyFilename: '/path/to/keyfile.json'
});
// Access an existing dataset and table.
var schoolsDataset = bigqueryClient.dataset('schools');
var schoolsTable = schoolsDataset.table('schoolsData');
// Import data into a table.
schoolsTable.import('/local/file.json', function(err, job) {});
// Get results from a query job.
var job = bigqueryClient.job('job-id');
// Use a callback.
job.getQueryResults(function(err, rows) {});
// Or get the same results as a readable stream.
job.getQueryResults().on('data', function(row) {});

google-cloud-node for BigQuery

15. ML APIs - Vision, Speech, Natural Language
Vision Natural Language Speech

16. google-cloud-node for Vision
var visionClient = vision({
projectId: 'grape-spaceship-123',
keyFilename: '/path/to/keyfile.json'
});
var gcsImageUri = 'gs://gapic-toolkit/President_Barack_Obama.jpg';
var source = {
gcsImageUri : gcsImageUri
};
var image = {
source : source
};
var type = vision.v1.types.Feature.Type.FACE_DETECTION;
var featuresElement = {
type : type
};
var features = [featuresElement];
var requestsElement = {
image : image,
features : features
};
var requests = [requestsElement];
visionClient.batchAnnotateImages({requests: requests}).then(function(responses) {
var response = responses[0];
// doThingsWith(response)
})
.catch(function(err) {
console.error(err);
});

17. Google Cloud - IoT Core
● Make informed decisions at Global Scale
● Securely connect your existing device network
● Establish two-way communication with your
devices
● Get straight to work

22. const mqttClientId = `projects/${argv.project_id}/locations/${argv.cloud_region}/registries/${argv.registry_id}/devices/${argv.device_id}`;
const connectionArgs = {
host: argv.mqtt_bridge_hostname,
port: argv.mqtt_bridge_port,
clientId: mqttClientId,
username: 'unused',
password: createJwt(argv.project_id, argv.private_key_file, argv.algorithm),
protocol: 'mqtts'
};
const client = mqtt.connect(connectionArgs);
const mqttTopic = `/devices/${argv.device_id}/${argv.message_type}`;
client.on('connect', () => {
//TODO …
}

24. ● Build add-ons to extend Google Sheets,
Docs, Slides, and Forms
● A living, breathing platform (well,
metaphorically)
● Free
Apps Script
