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

What is IoT…

Device Cloud BigData, ML, AISensor, BLE, NBIoT

microprocessor mips / arm x86 / x64 / unix iaas / paas / saas

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

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

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); }); });

BigQuery

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 - 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

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 …}

IoT Core - MQTT example

Google DataStudio

● Build add-ons to extend Google Sheets,

Docs, Slides, and Forms

● A living, breathing platform (well,

metaphorically)

● Free
