Connecting the Unconnected: IoT Made Simple

October 25th, 2016

Connecting physical devices to the cloud can enhance the user experience. AWS IoT is a new managed service that enables Internet-connected things (sensors, actuators, devices, and applications) to easily and securely interact with each other and the cloud. In this session, we will discuss how constrained devices can send data to the cloud and receive commands back to the device. Devices can securely connect using MQTT, HTTP and WebSockets protocols and developers can leverage several features of AWS IoT such as the Rules Engine and Thing Shadows to quickly and easily build a real connected product. This session will take a practical approach to developing real-world IoT and mobile applications in which the back end is serverless and can scale from one to virtually unlimited users without any infrastructure or servers to manage.

41. Device Gateway Millions of devices and apps can connect over
 MQTT,
 WebSockets,

 Pub/Sub Broker
 with Long-lived
 bi-directional messages
42. Rules Engine SELECT *
 FROM ‘things/thing-2/color’
 WHERE color = ‘red’ Simple & Familiar Syntax SQL Statement to define topic filter with JSON support Functions improve signal : noise
43. Device Shadow Intermitted Connections Persistent

44. Open Source AWS IoT Device SDK Embedded C JavaScript Arduino Yún Android iOS Java Python
45. MQTT
46. MQTT Topic Device A “Sensor” Device B “Control Center” (1) Subscribe (3) Message (2) Publish MQTT Topic = topic level / topic level / … ↓ “myapp/customer123/house4/kitchen/temperature”
47. Wildcards ‘+’ single level ‘#’ multi level “myapp/customer123/house4/+/temperature” “myapp/+/house4/kitchen/+” “myapp/customer123/house4/#” “myapp/customer123/#” “myapp/#” $topics are not subscribed by “#’”
48. Device Shadows
49. Device Shadows RESTful API https://endpoint/things/thingName/shadow endpoint = identifier.iot.region.amazonaws.com HTTP GET → GetThingShadow HTTP POST → UpdateThingShadow HTTP DELETE → DeleteThingShadow
