This document provides an overview of IoT and the AWS IoT platform. It discusses key IoT concepts like MQTT and smart home devices. It then details various aspects of the AWS IoT architecture including AWS IoT Core services, security, and pricing. Device SDKs and protocols are covered, as well as how AWS IoT integrates with other AWS services like Lambda, S3, DynamoDB through the AWS IoT rules engine. Device shadowing and registry services are also summarized. Finally, AWS IoT is compared to the Azure IoT Suite in terms of features.

17. 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

20. AWS IoT Rules Engine
RULES ENGINE
Transform messages
based on rules and
route to AWS Services

21. AWS IoT Rules Engine Basics
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.
SELECT * FROM ‘things/thing-2/color’
WHERE color = ‘red’

22. 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)}",
}]

23. AWS IoT Rules Engine
Complex Evaluations
Respond to the fleet, not just a single unit. Dozens of functions() available
Multiple / Simultaneous Actions
Sometimes a situation requires you to take many actions

appropriate endpoint based on
business rules.
External endpoints can be
reached via Lambda and Simple
Notification Service (SNS).

}
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

33. 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.
AWS IoT Thing Shadow
UPDATE: $aws/things/{thingName}/shadow/update
DELTA: $aws/things/{thingName}/shadow/update/delta
GET: $aws/things/{thingName}/shadow/get
DELETE: $aws/things/{thingName}/shadow/delete

Message Broker notifies groups of the fleet using Topic Patterns
Alert the fleet (or part of it) of the update, and send the URL to the S3 download
Firmware Update
Stored in S3
Publish to groups of devices
• Ability to update global
or within a Region
• Rules Engine keeps
state of updates and
tracks progress in a
DynamoDB Table
• Store Version in
