12. 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

19. 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.

48. 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

49. 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

// 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“ });

67. 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.
