AWS IoT Message Broker


MQTT and HTTP

AWS IoT Message Broker

Standard Protocol Support (no lock-in)

Millions of devices and apps can connect

over any protocol starting with MQTT and

HTTP 1.1

Long-lived bi-directional messages

Clients (Devices and Apps) can receive

commands and control signals from the

cloud

Secure by Default

Connect securely via X509 Certs and TLS

1.2 Client Mutual Auth

Topic Based

Architecture

(lights/thing-2/color)

Highly Scalable

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

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

AWS IoT Rules Engine


based on rules and


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.

AWS IoT Rules Engine Basics

SELECT * FROM ‘things/thing-2/color’

WHERE color = ‘red’

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)}",

}]


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

3. External Endpoints

(via Lambda and SNS)

Rules Engine connects AWS

IoT to External Endpoints and

AWS Services.

2. Rest of AWS

(via Kinesis, Lambda,

S3, and more)


Rules Engine evaluates inbound

messages published into AWS

IoT, transforms and delivers to the

appropriate endpoint based on

business rules.

External endpoints can be

reached via Lambda and Simple

Notification Service (SNS).

Invoke a Lambda function

Put object in an S3 bucket

Insert, Update, Read from a

DynamoDB table

Publish to an SNS Topic

or Endpoint

Publish to a Kinesis stream

Continuous Improvement around Predication

Continuously look for outliers and re-calibrate the Machine Learning models

AWS IoT Rules Engine & Stream Data

N:1 Inbound Streams of Sensor Data (Signal to Noise Reduction)

Rules Engine filters, transforms sensor data then sends aggregate to Amazon Kinesis

Kinesis Streams to Enterprise Applications

Simultaneously stream processed data to databases, applications, other AWS

Device SDK

1. Device Publishes Current State

2. Persist JSON Data Store

3. App requests device’s current state

4. App requests change the state5. Device Shadow sync’s

updated state

6. Device Publishes Current State7. Device Shadow confirms state change

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

S3 Holds Versioned Firmware Distributions

Organize and secure your firmware binaries in S3

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
