TRANSCRIPT
is made for IoT Michael Kuehne
Head of Dev @ cybus
Who are these IoT Developers?
Some Numbers Javascript = Prefered Language of ~ 58% IoT Developers
~ 56% IoT Developers = Hobbyists with Non-IoT Background
What are they develop? App for Existing Device (Smart Watch)
Standalone Device (Fitness Band)
Integ. Limited # of Sensors (Hub)
Integ. Devices in Network (Smart City)
Combining Data from Mult. Sources (Health App)
Data Aggreg. From Exisitng Devices (Air Quality)
Back-end Development
VisionMobile „IoT Developer Landscape 2015“
Cybus: A Middleware for the Industrial Internet of Things
Security Monitoring Maintenance Efficiency Sovereignty
Async
Why Node.js?
Single Threaded
Event-Driven, Non Blocking I/O Model
Speed, Scalability & Efficiency of JS and V8
Well-proven for APIs & Microservice Architecture
Well-developed IoT Modules
„The Node.js community made node.js THE platform for IoT“
Supported Protocols

Demo Time Let‘s move...
But how?
Node-RED
A visual tool for wiring the Internet of Things
created by IBM
Pulls different device APIs and online services together
Extendable with plugins written in node.js
Written in node.js
Rapid Prototyping for IoT

Demo Time Let‘s talk...
But there‘s so much more
Conclusion
Node.js is made for industrial IoT
One Language for the whole plattform
Less Resources but Speed
Great for Microservice Architecture
Supports & Integrates different industrial protocols
