30. Creating certificates & keys

31. Key & certificate creation with the AWS CLI

32. Device Provisioning at Scale:
How do you getting keys &
certificates onto your devices?

33. Getting keys & certificates onto your devices
• Simple at the device prototyping stage
• Copy or flash them (& the CA cert) onto your device
• More complex in volume manufacturing
• Still copying or flashing keys & certs, but the numbers increase
• Use AWS SDKs/CLI to automate key & certificate creation.
Provide keys & certificates to your device manufacturing partners

34. Register on first use

35. https://aws.amazon.com/blogs/iot/just-in-time-registration-of-device-certificates-on-aws-iot/

41. Communicating with Things

42. AWS IoT Message Broker
DEVICE GATEWAY
Communicate with devices via
MQTT and HTTP

43. AWS IoT Message Broker

44. 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

45. AWS IoT Message Broker : managed service
Highly Scalable
Device Gateway
Millions of devices
sending billions of
messages

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’

50. 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)}",
}]

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

REGISTRY
Identity and Management of
your things

57. AWS IoT Thing Registry
• Static attributes associated to Thing
• Firmware version
• Serial Numbers
• Device Type
• Device Group
• Device Description
• Sensor description
• Support and Maintenance
• Reference Manual URL
• Part # reference
• Reference to external support system

58. AWS IoT Thing Registry: Create & List Things
http://docs.aws.amazon.com/iot/latest/developerguide/thing-registry.html
$ aws iot create-thing --thing-name "MyLightBulb" --attribute-payload "{"attributes": {"wattage":"75", ”model":"123"}}"
{
"thingArn": "arn:aws:iot:eu-west-1:554625704737:thing/MyLightBulb",
"thingName": "MyLightBulb"
}
$ aws iot list-things
{
"things": [
{
"attributes": {
"model": "123",
"wattage": "75"
},
"version": 1,
"thingName": "MyLightBulb"
}
]
}

59. AWS IoT Registry: Search for Things
http://docs.aws.amazon.com/iot/latest/developerguide/thing-registry.html
$ aws iot list-things --attribute-name "wattage" --attribute-value “75"
{
"things": [
{
"thingTypeName": "StopLight",
"attributes": {
"model": "123",
"wattage": "75"
},
"version": 3,
"thingName": "MyLightBulb"
},
{
"thingTypeName": "LightBulb",
"attributes": {
"model": "123",
"wattage": "75"
},
"version": 1,
"thingName": "MyRGBLight"
}
]
}

60. AWS IoT Registry: Thing Types
http://docs.aws.amazon.com/iot/latest/developerguide/thing-registry.html
Thing types allow you to store description and configuration
information that is common to all things associated with the same
thing type.
For example, you can define a LightBulb thing type. All things
associated with the LightBulb thing type share a set of attributes.
aws iot create-thing-type --thing-type-name "LightBulb"
--thing-type-properties "thingTypeDescription=light bulb type, searchableAttributes=wattage,model"

61. Device State Cache:

"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

67. AWS IoT Device Shadow Topics (MQTT)
Thing SDK makes it easy for you to
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

LED1 RED YELLOW
LED1 = Yellow
TEMP = 60FACCEL X=1,Y=5,Z=4 X=1,Y=5,Z=4
