• 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

IoT: The Internet of Toasters Things

Internet of thingsnoun A proposed development of the Internet in which everyday objects have network connectivity, allowing them to send and receive data.
What is the Internet of Things?

The Origin StoryKevin Ashton, 1999
Source: Kevin Ashton, “That ‘Internet of Things’ Thing: In the real world, things matter more than ideas”, RFID Journal, June 2009, sourced by Nick Landry 9
“If we had computers that knew everything there was to know about things
—using data they gathered without any help from us—
we would be able to track and count everything, and greatly reduce waste, loss and cost.
We would know when things needed replacing, repairing or recalling, and whether they were fresh or past their best.”

• 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

Common IoT Devices & Platforms
33Source: 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

38
• 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

39
• 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)
Raspberry Pin Out

• LEDs are everywhere• Light-emitting diode – converts
electrical energy to light• The basic LED circuit is simple,
connect everything in serial• The electricity flows through
each component, thus lighting the bulb
• Direction manners
LED and Circuit Basics
43
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

• Capacitor (to reduce line noise)

• Serial Communications happen over 4 lines• Yellow• White• Blue• Green
• Yellow connects Temp sensor to the Convertor
Communicating with the RPi

Stream Analytics
57
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
58
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”
59
Tumbling Window Hopping Window

• 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
60Source: 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?
61
• Create Stream Analytics Job• Configure 1 or more Inputs and Outputs• Create Queries to ETL from Inputs to Outputs• Use SQL-like language
