Device Gateway
AWS IoT Message Broker
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

• 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

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

SELECT DATA FROM…
• SELECT *
• SELECT deviceid, temp
• SELECT coords.latitude
• SELECT a.another_level.b
• Returns {“b” : 3}
• SELECT a..b
• Returns {“b” : 3}

SAMPLE PAYLOAD
AWS IoT – SQL Reference
SELECT DATA FROM…
• SELECT deviceid AS client
• SELECT md5(deviceid) AS hashed_id
Substitution Templates
• ${expression}
• ${topic() - md5(deviceid)}
• ${deviceid - temp}
{
“deviceid” : “iot123”,
“temp” : 54,
“humidity” : 32,

}}
}
SAMPLE PAYLOAD
AWS IoT – SQL Reference
SELECT DATA FROM TOPIC WHERE FILTER
• Like scanning a database table
• Default source is an MQTT topic
EXAMPLES:
• FROM mqtt(‘my/topic’)
• FROM mqtt(‘my/wildcard/+/topic’)
• FROM (‘my/topic’)
AWS IoT – SQL Reference
SELECT DATA FROM TOPIC WHERE FILTER
Token Meaning Example
= Equal, comparison color = 'red'
<> Not Equal, comparison color <> 'red'
AND Logical AND color = 'red' AND siren = 'on'
OR Logical OR color = 'red' OR siren = 'on'
() Parenthesis, grouping color = 'red' AND (siren = 'on' OR isTest)
+ Addition, arithmetic 5 + 3
- Substitution, arithmetic 5 - 4
/ Division, arithmetic 8 / 2
