• You rarely get the chance to practice for practice’s sake• IoT and cloud architecture/development patterns can be

confusing and are frankly “new” to many of us• It’s not what’s going to change, it’s when – and the answer is likely

yesterday

• Today• The Internet of Things (IoT)• Cloud architecture• See an end-to-end solution• Hands-on practice• Get excited or inspired

Practice Makes Perfect

Common IoT Devices & Platforms

19Source: Nick Landry

• Full single-board computer with SoC• Average cost: $30 to $45• Model A, A+, B, B+ and Raspberry Pi 2 B,

3, Zero• Runs Linux – flavor of Debian called

Raspbian• http://www.raspbian.org

• Huge accessory selection• Programmable

• Python• (Mono), etc.

• 5+ million units sold in 3 years of manufacture, technically the largest computer manufacturer in UK!

Raspberry Pi

• Prototype-to-production platform• Wifi or Cellular enabled, low-voltage • Remote management capabilities• Cloud-based development environment• $19• Scale by starting with 1, move to

a PCB integrated platform, and custom hardware when you get tothe 10,000’s

The RPi can be powered either by the USB cable from the host PC or by an external DC power source (5V).

The RPi also has 5V, 3.3V and GND pins to supply voltages to your project components.

Raspberry Pi 2 Introduction

• General Purpose Input/Output• Pin that can be controlled by

the user• Can be set to input or output • Input can be things like

temperature sensors, buttons, IR etc

• Output can be LEDs, Motors, LCDs etc

GPIO

25

• 40 pins total• Pi Wedge organizes pins• 17 GPIO• 6x power• 5x SPI (Serial Peripheral

Interface) serial comm.• 2x UART, Tx (out) / Rx (in)

serial comm.• 4x I2C (comm. Protocol,

master/slave)

Breadboards offer a great way to prototype circuits. The provide a number of “buses” for connecting both power and components

Power buses run the entire horizontal length

Component buses (vertical) give you easy ways to connect pins together

Lab 3 Temperature Sensor

35

• Analog Temp. Sensor• Analog to Digital

Convertor (RPi 2 only reads digital signals, so we need a convertor from Analog to Digital)

• Capacitor (to reduce line noise)

Temperature Sensor Components

36

• Red are Power and GRD• Analog/Digital

Convertor (1 set for the analog component, another for the digital component)

• Temperature Sensor

Powering the Circuit

• Serial Communications happen over 4 lines• Yellow• White• Blue• Green

• Yellow connects Temp sensor to the Convertor

Communicating with the RPi

• PaaS is where you “should” want to be• Use the service, don’t do the plumbing• We’ve been doing the plumbing for a long time• Challenges

• Mapping exercise• Architect the

PaaS way or thehighway

Stream Analytics

58

Standard Data Analysis• Your data already exists –

it’s all from the past or projections of the future

• You can aggregate everything

• Not real-time• Batch processing• Reactionary in nature

Data Analysis

59

Streaming Data Analysis• Data arrives temporally • You can’t aggregate data all at once• Real-time• Data is grouped into different

windows

Data Analysis

• What is a data window?• What’s your data window?• Concept: arriving data as an “event”

60

Tumbling Window Hopping Window

Source: MSDN and MSDN

• Tumbling Windows that overlap• Timeunit (minutes, seconds, etc.)• Windowsize (duration)• Hopsize (skip duration)

• Series of fixed-size, non-overlapping and contiguous time windows

Temporal Windowing

61Source: Microsoft

• Real-time stream processing in the cloud

• Real-time cloud-based ETL• Millions of events per second• Scale dynamically

What is Azure Stream Analytics?

62

• Create Stream Analytics Job• Configure 1 or more Inputs and Outputs• Create Queries to ETL from Inputs to Outputs• Use SQL-like language

Making Cloud ETL Easy
