3. Topics
• Internet of Things – An Intro
• Why Cloud for IoT
• Azure IoT services
• IoT Protocols
• Microsoft OS for IoT
• Devices for IoT
• Demo

4. Internet of Things (IoT)
• Connecting Heterogeneous systems
seamlessly in to information network to
achieve business and social values
• 25 Billion Connected things on 2020 (
More than Human population in the
world)
• IoT, M2M , Intelligent systems etc..
Converging the same
• Examples
• Smart Home, Smart City, Smart Hospitals,
Smart …..

5. Evolution of IoT
• Earlier IoT systems
• Expensive on installing and maintaining
• Difficult implementation (No standard protocols, services etc..)
• Why IoT is booming?
• Cheaper hardware (sensors, processor boards, RF devices etc..)
• More standardization on Hardware platforms
• M2M protocols and easy connectivity of Heterogeneous systems

6. Why Cloud (Azure) for IoT?
• Cloud - Back bone of IoT
• Highly scalable
• Connecting millions of devices
• Enormous storage, processing capacity
• Connecting Heterogeneous systems
• PCs, Mobiles, bigger devices to smaller
devices running on various OS
• Data Analysis to create business value
• (ex) Vending Machines
• Variety of cloud services

8. Azure Event hub
• Part of Azure Service Bus
• Handling Telemetry Messages from devices, Apps and websites
• Logging millions of events/second
• Connect millions of devices across platforms
• Time-based event buffering
• Elastic scale in order to accommodate variable load profiles
• Accessible through AMQP and HTTP protocols

9. Demo on Event hubs

10. Azure Stream Analytics
• Real-time stream processing in the cloud
• Processing Millions of Events / second
• Simple SQL-like language to define your stream processing logic
• No hardware to deploy

11. Demo on Stream Analytics

12. IoT Communication Patterns
Telemetry
Information flowing
from a device to other
systems for conveying
status of device and
environment
Inquiries
Requests from devices
looking to gather
required information or
asking to initiate
activities
Commands
Commands from other
systems to a device or a
group of devices to
perform specific
activities
Notifications
Information flowing
from other systems to a
device/group for
conveying status
changes in the world

13. Popular IoT Protocols
• Alljoyn (https://allseenalliance.org/)
• Open source framework for IoT
• Initiated by Qualcomm and now it is growing bigger (Maintained by Allseen
Alliance)
• SDKs available for Windows/WEC, Linux, Android, iOS,
• .net MicroFramework (Available soon)
• SDK types
• Standard SDK
• Thin client SDK – for resource constrained devices
• Microsoft adopting this as a service in Windows 10 (various versions)

14. Popular IoT Protocols
• MQTT (http://mqtt.org/)
• Available in the industry for more than 10 Year
• Open standard by IBM and adopted by many org
• Extremely lightweight publish/subscribe messaging transport
• Support for Windows/WEC, .net Micro framework, Linux, Android, iOS,
• Broker (server)/ Client Mechanism
• https://m2mqtt.codeplex.com/ - .net code for MQTT

15. Windows IoT AllJoyn Device Network

18. Microsoft OS for IoT
• Windows Embedded Compact
• Used to build any X86 and ARM core based devices (earlier version support
MIPS Arch)
• Extremely customized
• OS foot print on MBs (<100MB)
• Suitable for devices with low power, low processing core(300 MHz to 1GHz
and above) and RAM (64 MB to ~3 GBs) and minimum ~64MB and above
• Native Win32 and .Net CF
• Broader range of connectivity support
• Windows Embedded Handheld
• Earlier WEH is based on Windows Embedded compact based kernel
