Thinking Strategically about The Internet of Things Holly Cummins @holly_cummins
I’m from IBM’s Bluemix Garage. @holly_cummins
Me I would like the Bluemix Garage to help me with an IoT project. Customer Oooh! I love the internet of things! @holly_cummins
This is what I’m imagining when I hear ‘Internet of Things.’ @holly_cummins

Computers are now ubiquitous in almost everything we interact with. @holly_cummins
@holly_cummins
These computers are now going online. @holly_cummins
These computers are now going online. 9 billion of them are online now. @holly_cummins
These computers are now going online. 9 billion of them are online now. There will be 20 - 50 billion connected devices by 2020. @holly_cummins

Demo. Anyone want popcorn? @holly_cummins
popcorn maker application server http hungry user raspberry pi MQTT MQTT MQTT Watson IoT foundation (MQTT broker) http Edimax smart plug @holly_cummins
@holly_cummins
Is this actually useful? @holly_cummins
The problem we were solving was that we needed an excuse for a popcorn maker at work. :) @holly_cummins

I’ve got form in this area. @holly_cummins
@holly_cummins
There’s a WebSphere server running in that hat. Very useful. Obviously. @holly_cummins

Do we really want a future where our interaction with everything is mediated by a smartphone? @holly_cummins
The power comes from connections. @holly_cummins

We can solve so many incredible problems. @holly_cummins
Imagine … pill bottles that light up when it’s time to take the medicine. @holly_cummins
Imagine … facto ries tha t know what’s (Industry 4.0) happen ing insid e them. @holly_cummins
Imagine … cameras that detect wear in springs as as a train runs by. @holly_cummins
Imagine … cars that figure out how the next generation of cars should be built. @holly_cummins
Imagine … knowing the exact weather conditions, everywhere. @holly_cummins
Macroscopes will help us understand Earth’s complexity in infinite detail. Unlike the microscope, a “macroscope” harnesses data from billions of IoT devices using software and algorithms to address large-scale challenges such as availability of food, water and energy. @holly_cummins
Tools Learning @holly_cummins
Data. Lots of It. @holly_cummins
We want to be able to predict equipment failure, so we’ve wired up our factory for IoT. Me Customer @holly_cummins
We want to be able to predict equipment failure, so we’ve wired up our factory for IoT. Me Good idea! Customer @holly_cummins
We want to be able to predict equipment failure, so we’ve wired up our factory for IoT. Me Good idea! Customer That was a few years ago. We’re not doing anything with the data… @holly_cummins

You’re going to need a data lake. @holly_cummins
You’re going to need a data lake. … and if you never use what’s in the data lake, that’s a big missed opportunity. @holly_cummins

How about … we educate ourselves and make better design decisions? @holly_cummins

Reliability @holly_cummins
“ Holly, I s aw a vide o of your throwable application server talk. I thought you handled the fact that the demo failed really well. Are there any videos where it actually works?” - My mother @holly_cummins
software network hardware @holly_cummins
What could possibly go wrong? software network hardware @holly_cummins
The more moving parts, the more opportunity for failure. @holly_cummins
But …what does it all mean? @holly_cummins
What can you imagine for your domain? @holly_cummins
Questions? @holly_cummins
Cool? Useful? Disruptor? All of the above? IoT is having an impact on more and more industries. As the cost of instrumenting things and collecting data drops, the possibilities for what we can control and the kind of insights we can gather increase. Not only is IoT hardware cheaper and more pervasive, developing IoT software is now far more accessible. That doesn’t mean there aren’t tricky bits. Does Java have relevance in the IoT world? How can you keep the system reliable and handle failure in a cost-effective way? How can you cope with the data volumes? What’s the best way to turn raw data into insight?
