Agenda The Internet of Things – Concept and Scenarios Azure Skies for Kinder(s)
The application concept The software architecture
Demo: Azure service and Compact Framework client WinCE 7.0
About the platform Development prerequisites: hardware, toolset,
frameworks Demo: Windows CE 7 Silverlight UI (C++ native code) Pros & Cons – thinks we liked, problems we faced Solution economics: let’s talk about money

The Internet of Things: Concept
A network of Internet-enabled objects, together with web services that interact with these objects.
Based on network ubiquity Ubiquity = omnipresence - present everywhere at
the same time (philosophy)Smart-devices, sensors, RFID build-up the network
It's time to intersect and link them with the cloud.

The Internet of Things: Scenarios
Health: monitored the peacemaker (heart diseases)
Businesses: link business processes (BizTalk, SAP) with production processes
Transportation: monitor the goods moving through RFID
… infinite number of possibilities
All scenarios have in common smart devices geographically spread connected through the internet with a backend

Azure Skies for Kinder(s)Concept
Let’s face a reality children love technology allow them to have it in a controlled
and less dangerous way
Multimedia room for Kindergarten Teacher defines content Educational videos, picture albums Educational applications: learning to pronounce, write, draw Psychological and emotional development lessons and tests Educational games (strategy, chase, …)
Child uses content Device/Station with shock resistant touch screen and a very
limited number of soft keys

Pros & ConsPros:
A lot of hardware available on the market Stable operating system –15 years of evolution Protected memory Support from Microsoft .NET Compact Framework (productivity)
Cons: Incomplete managed API in contrast with Google
Android Java API Not possible to call from a native application
managed code Only C/C++ APIs for connectivity (Bluetooth,
USB…) Productivity issues

Solution economicsOne can build a wide range of embedded systems with relative low costsWindows CE 7 – 20-3.7 USD (based on quantity)
Embedded hardware/board: 150-250 USDOther peripherals: 200 USDTotal: min 160 USD, max 500 USD
The Cloud may cut the costs of hosting your own infrastructure for the backend, while ensuring scalability infrastructure costs (hw + sw), usually underutilized
management costspay as you go
