AWS IoT Device Gateway

Standard Protocol Support (no lock-in) Millions of devices and apps can connect over any protocol starting with MQTT and HTTP 1.1 Powerful Pub/Sub Broker with Long-lived bi-directional messages Clients (Devices and Apps) can receive commands and control signals from the cloud Secure by Default Connect securely via X509 Certs and TLS 1.2 Client Mutual Auth

Topic Based Architecture

(lights/thing-2/color)

Highly Scalable Device Gateway

MQTT

MQTT vs HTTPS: •  93x faster throughput •  11.89x less battery to send •  170.9x less battery to receive •  50% less power to keep connected •  8x less network overhead

Source: http://stephendnicholas.com/archives/1217

•  OASIS standard protocol (v3.1.1) •  Lightweight, pub/sub transport protocol

that is useful for connected devices •  MQTT is used on oil rigs, connected

trucks, and many more sensitive and resource-sensitive scenarios.

•  Customers have needed to build, maintain and scale a broker to use MQTT with cloud applications

Protocols – MQTT – Keep Alive

PINGREQ

PINGRESP

Although TCP/IP in theory notifies you when a socket breaks, in practice, particularly on things like mobile and satellite links, which often “fake” TCP over the air and put headers back on at each end, it’s quite possible for a TCP session to “black hole”, i.e. it appears to be open still, but in fact is just dumping anything you write to it onto the floor. Andy Stanford-Clark on the topic “Why is the keep-alive needed?“ *

AWS IoT Rules Engine

RULES ENGINE Transform messages based on rules and

route to AWS Services

Simple & Familiar Syntax -  SQL Statement to define topic filter -  Optional WHERE clause -  Advanced JSON support Functions improve signal : noise -  String manipulation (regex support) -  Mathematical operations -  Context based helper functions -  Crypto support -  UUID, Timestamp, rand, etc.

AWS IoT Rules Engine Basics

SELECT * FROM ‘things/thing-2/color’ WHERE color = ‘red’

AWS IoT Rules Engine’s Flexibility

SELECT *, clientId() as MQTTClientId FROM 'one/rule' !WHERE !startsWith(topic(2), 'IME33') AND (state = 'INIT' OR hydro_temp > surface_temp)",!"actions": ![{ !"republish": {!

!"topic": ! ! !"controllers/${substring(topic(3), !3, 5)}",!}] !

APPLICATIONS

AWS IoT Thing Shadow

Shadow

AWS IoT Shadow Flow

Shadow

Device SDK

1. Device Publishes Current State

2. Persist JSON Data Store

3. App requests device’s current state

4. App requests change the state 5. Device Shadow sync’s updated state

6. Device Publishes Current State 7. Device Shadow confirms state change

AWS IoT

AWS IoT Device Shadow - Simple Yet Powerful

{ "state" : { “desired" : { "lights": { "color": "RED" }, "engine" : "ON" }, "reported" : { "lights" : { "color": "GREEN" },

"engine" : "ON" }, "delta" : { "lights" : { "color": "RED" } } }, "version" : 10 }

Thing

Report its current state to one or multiple shadows Retrieve its desired state from shadow

Mobile App

Set the desired state of a device Get the last reported state of the device Delete the shadow

Shadow

Shadow reports delta, desired and reported states along with metadata and version

AWS IoT Device Shadow Topics (MQTT)

Thing SDK (C-SDK, JS-SDK) makes it easy for you build shadow functionality into your device so it can automatically synchronize the state with the device.

Simple Pay as you go and Predictable Pricing

•  Pay as you go. No minimum fees •  $5 per million messages published to, or delivered

in US East (N. Virginia), US West (Oregon), EU (Ireland) $8 in Asia Pacific (Tokyo)

AWS IoT

Free Tier 250,000 Messages Per Month Free for first 12 Months

Pricing Example

100 sensors * 30 days * 24 hours * 60 minutes = 4.38 million messages

1 meter * 100 readings * 30 days * 24 hours * 60 minutes = 4.38 million messages

100 Sensors: Publishing 1x/minute

DynamoDB Table: Receives all Sensor Data

Metering Unit: Receives all Sensor Data

1 table * 100 readings * 30 days * 24 hours * 60 minutes = 4.38 million messages

4.38 million publishes from sensors: 4.38 * $5 = $21.90 4.38 million deliveries to a metering unit: 4.38 * $5 = $21.90

4.38 million deliveries to DynamoDB: $0

AWS IoT SDK for Javascript

// Enable AWS SDK for JavaScript support using a service model file var myService = new AWS.Service({apiConfig: require('./path/to/service-model.json'), endpoint: "service endpoint"}); // Initialize SDK var aws = require('aws-sdk'); var iot = new aws.Service({apiConfig: require('./iot-service-model.json'),

endpoint: ”iot.us-east-1.amazonaws.com” }); var iotData = new aws.Service({apiConfig: require('./iot-data-service-model.json'), endpoint: "data.iot.us-east-1.amazonaws.com“ }); // Publish message on MQTT topic var params = { "topic" : "foo/bar", "payload" : "hello world" }; iotData.publish(params, function(err, data) { console.log(err, data);});

Common Design Architectures with AWS IoT

Using Smartphone as a hub

Intel Edison AWS cloud

Amazon Cognito

Mobile Application

•  No connectivity: Very limited resources / Saving costs •  Security: Use Amazon Cognito to securely send data to AWS IoT or to the

AWS cloud •  Hub: Use Smartphone’s capabilities (WiFi/4G)

Building Automation / Mobile Control of IoT

•  Dynamic Automation: Dynamically respond to Events happening in the Factory

ex. Opening doors and requesting assistance when emergency button is pushed

•  Mobile Control: Simplify mobile control of IoT/Factory automation devices with AWS IoT rules

Launching AWS IoT Hardware Program

The AWS IoT Hardware Program helps AWS customers build connected products using any hardware platform. IoT Hardware Partners reduce the time to market and improve customer experiences by providing necessary tools, SDKs and sensors to connect their devices to AWS. The program is designed for partners that provide hardware (semiconductors, connectivity modules, sensors, actuators) to customers and are interested in connecting their hardware platform to AWS.
