Topics• Internet of Things – An Intro

• Why Cloud for IoT

• Azure IoT services

• IoT Protocols

• Microsoft OS for IoT

• Devices for IoT

• Demo

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 …..

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

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

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

Demo on Event hubs

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

Demo on Stream Analytics

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

Popular IoT Protocols

• Alljoyn (https://allseenalliance.org/)• Open source framework for IoT

• Initiated by Qualcomm and now it is growing bigger (Maintained by AllseenAlliance)

• 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)

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

Azure for IoT future roadmap

• Azure IoT suite• Evolution of Azure Intelligent systems services• Based on Azure service bus• Device Repository, Event storage, Set Alerts, Commands and perform

Analytics

• Device Gateway – Reykjavik project• IoT Gateway in the Cloud• Based on Service Bus

• Queues• Topics/Subscriptions• Event Hubs

• Released as open source on GitHub• Access using HTTP, AMQP, MQTT, CoAP and custom protocol gateway

Configs

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

• Latest versions are based on Windows Phone 8.1 Kernel

• License provided selected OEM

Microsoft OS for IoT ( Cont..)

• Windows Embedded Standard/Industry• X86 based devices• Customized version of Windows PC operating systems• Image foot prints are larger and similar to PC but it is componentised

• .NET Micro Framework• Open source OS• ARM Architecture (ARM7, ARM9 and ARM Cortex M)• Suitable for resource constrained devices (256 KB of Flash and 64KB of RAM)• C# Managed code ( A sub set of .net base class libraries)• https://amqpnetlite.codeplex.com/ - AMQP for accessing Service Bus ( Event

hubs)
