4. Mobile is the new interface

5. One billion consumers will have smartphones by 2016. US consumers alone will own 257
million smartphones and 126 million tablets.
In 2016, 350 million employees will use smartphones — 200 million will bring their own
(BYOD). Employees pay for more than half of the devices and data plans used for work.
Mobile spend will reach $1.3 trillion (35% of tech spend) as the mobile apps market
reaches $55 billion in 2016. Tablet and smartphone apps, at average price of $2.43, will
grow explosively to $56 billion in 2015.
Business spending on mobile projects will grow 100% by 2015. Most major businesses
now have a tablet strategy for sales reps. IT professionals will respond to the onslaught by
diverting IT budgets to mobile technology.
Mobile commerce is expected to reach $31 billion by 2016, 7% of overall eCommerce,
representing a compounded annual growth rate of 39% from 2011 to 2016.
Mobility is (obviously) a big deal . . .

8. So how ready are we for the new UX ?

9. Everyone understands the problem!
No one has an answer, until now!
Well, it appears to me
that the problem is on
your end.
And thus was born the
most revered phrase
in tech support.

10. What needs to be built ?
Front Edge
Thousands to Millions of devices connecting to business APIs
creating the new user experience
APIs for each device, each app, each screen. Optimized for bandwidth &
battery, adjusting to each device’s capabilities

11. Highly concurrent
Scriptable
(the teams already know JavaScript)
Giant ecosystem of reuseable components
(just like in the browser)
Keeps device-specific APIs from polluting core SOA
11
Node.js is the perfect match

12. Vast open-source community
(70 K re-usable modules)
Reduce development time by
50% or more
Reuse existing UX tools
Low latency - Mobile
Event-driven and fast by
design: 50x faster
Non blocking, high throughput:
helps scale 20x
Why do 3 million developers download every release of Node.js

13. Some performance stats
Hardware Utilization
Benchmarking
Performance
Outcomes : counting
―faster‖ endpoints per
application

14. Some users of Node in mainstream enterprise
Transportation Gaming Chat & Social
Analytics & Big Data
Multi-media
Advertising Financial
Wearable & Embedded/Sensor Retail & Consumer
Tech & Cloud
Exposing
enterprise data
to these
chatty, highly
concurrent, mo
bile and web
apps in form of
an easily
consumable
API helps
create ―Rich
Apps‖, useful
for genuine
business
needs.

22. How it works – Create or consume multiple data sources

23. How it works – Data discovery & relationship modeling

24. How it works – JSON API generation

25. How it works – API security configuration

26. Automatic Data modeling and REST API publishing

27. Mobile SDKs (iOS SDK) for remotable integration

29. Node.js challenges for Enterprise
Lack of best practices
No enterprise version
Weak tool chains & monitoring
Missing production-class features:
– Auto-scaling
– Certified run-time
– Event/error management
– Root cause tools

30. StrongLoop Backs Node
30
