• 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

Internet of things

noun

A proposed development of the

Internet in which everyday objects

have network connectivity, allowing

them to send and receive data.

• 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 to

the 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.

• 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

• 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

• 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

• Red are Power and GRD

• Analog/Digital

Convertor (1 set for

the analog

component, another

for the digital

component)

• Temperature Sensor

• 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 the

highway

Stream Analytics

Standard Data Analysis

57

• 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

Streaming Data Analysis

58

• 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”

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

Source: Microsoft 60

• 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

Making Cloud ETL Easy
