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. We have partnered with several hardware manufacturers to make it super easy for you to build your next dream machine. In this session, you will see how you can connect a real device to AWS IoT and accelerate your prototype development using Device SDKs. We will cover major hardware platforms from Arduino, Marvell, Dragonboard and MediaTek, protocols like MQTT/HTTP, various starter kits available so you can get started quickly..

Any device can connect securelyAnyone can connect a device Getting started is easy
“Securely connect one or one-billion devices to AWS,
so they can interact with applications and other devices”

10. Protocols – MQTT
MQTTS 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

• 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

17. 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.

Thing
Report its current state to one or multiple shadow
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

19. Protocols – AWS IoT Shadow Topics (MQTT)
$aws/things/{thing}/shadow/…
Publish
…/get: to get the latest shadow state
…/update: to update the shadow state
…/delete: to remove the shadow state
Subscribe
…/accepted: shadow accepted message
…/rejected: shadow rejected message
…/delta: differences between desired and reported
DEVICE SHADOW
Persistent thing state
