What Constitutes On-Premises Infrastructure?

Sensors & IoT DevicesData CentreInfrastructure

Challenges Of Devices Living On The Edge

Round-trip latency

Intermittent connectivity

Expensive bandwidth

Programming and updating embedded software needs specialized skills

Limited to what is on the device unless you rewrite or program the device

How does it work?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

Republish to AWS IoT

All with no servers, of course

I want to do this. Right now!

HARDWARE YOU WILL (& MIGHT) NEED

• A Raspberry Pi

• Electronics Kit • Try the SunFounder 37 modules Sensor Kit v2.0 for Raspberry Pi

3, 2, Model B+ with 40-Pin GPIO Extension Board & Jump Wires • http://www.amazon.co.uk/dp/B014PF05ZA • Example tutorial

• Raspberry Pi Sense Hat (optional fun) • https://www.raspberrypi.org/products/sense-hat/

SETTING UP FOR GPIO/SENSE HAT

Your own electronics/sensor build C (for embedded C)

http://wiringpi.com Python Wrapper Module for WiringPI

https://github.com/WiringPi/WiringPi-Python

For the Sense Hat Python Module

https://github.com/RPi-Distro/python-sense-hat

SETTING UP FOR AWS IOT

Use the AWS Console to create your device

Download the required crypto materials & save the C header file contents with your endpoint, cert, and key details

Download & set up your chosen AWS IoT SDK Get them at : https://aws.amazon.com/iot/sdk/

Building the C SDK on the Raspberry Pi requires the CppUTest library from: https://github.com/cpputest/cpputest/releases/tag/v3.6

Get started with the sample applications that come with the AWS SDKs

EXAMPLES & DEMOS
