This is a presentation Chris Pietschmann gave to the Milwaukee Azure (http://MkeAzure.com) group on 8/17/2016 covering where to get started building IoT solutions using Microsoft Azure, Windows IoT Core, and Raspberry Pi. No IoT solution is complete without hardware so he will be using Windows IoT Core on a Raspberry Pi 3 to read from sensors and send that data to the cloud. This presentation will cover what you need to get started building IoT solutions using the Microsoft Azure platform.

4. The Internet of Things

5. IoT Devices

6. Agenda
•IoT Architecture
•Raspberry Pi
•Windows IoT Core
•Azure IoT

7. IoT Architecture

8. Device-to-Cloud Messaging
• Data Event / Messages are sent from the hardware device to the
cloud
• Sensor readings
• Telemetry stream
• Generally feeds into some kind of Message Queue for
processing

9. Lambda Architecture
• Data Aggregation
• Real-Time Processing /
Analytics
• fast
• Batch Processing
• slow

10. Cloud-to-Device Messaging
• Command / Messages sent to the hardware device
• Instruction to perform an action
• Turn something on: Light, Fan, Open Door, etc
• Start / Stop gathering telemetry
• 2-way messaging

11. MQTT Protocol
• Message Queuing Telemetry Transport
• Publish / Subscribe, simple and lightweight protocol
• Encryption performed using SSL
• Designed for low-bandwidth, high-latency or unreliable
networks
• Created in 1999 http://mqtt.org

12. Other Protocols
• AMQP
• Advanced Message Queuing Protocol
• http://amqp.org
• HTTP
• Standard web protocol
• Custom or Device Specific
• Legacy or Proprietary

13. IoT Gateways
• Similar to a Proxy
• Provide aggregation point for device communications
• Field Gateway
• Low powered or simple devices may not have capacity to provide security
necessary for IoT; maybe no SSL
• Protocol Gateway
• Provides protocol adaptation
• Translates from custom / proprietary protocol to one cloud supports; like
MQTT or AMQP
• Offers a single security attack vector connected to Internet

14. IoT Architecture
