“It may be better to think of tablets, laptops and
desktops as one 'big screen' segment, all of which
compete with smartphones”

Defining Mobile First
1. Mobile is exploding
Mobile First ensures companies have an experience available to this extremely fast growing
user base widely considered to be the next big computing platform.
2. Mobile forces you to focus
Mobile devices require software development teams to focus on only the most important
data and actions in an application. There simply isn't room in a 320 by 480 pixel screen for
extraneous, unnecessary elements. When a team designs mobile first, the end result is an
experience focused on the key tasks users want to accomplish without extraneous detours
and general interface debris.
3. Mobile extends your capabilities
New mobile application platforms are introducing capabilities that leave PC-based Web
browsers behind: precise location information from GPS; user orientation from a digital
compass; multi-touch input accelerometer.

Requirements

API First as a Cultural Change
Amazon CEO Jeff Bezos mandate, from Steve Yegge post on Google+
1) All teams will henceforth expose their data and functionality through service interfaces.
2) Teams must communicate with each other through these interfaces.
3) There will be no other form of interprocess communication allowed: no direct linking, no
direct reads of another team’s data store, no shared-memory model. The only communication
allowed is via service interface calls over the network.
4) It doesn’t matter what technology they use. HTTP, Corba, Pubsub, custom protocols —
doesn’t matter. Bezos doesn’t care.
5) All service interfaces, without exception, must be designed from the ground up to be
externalizable. That is to say, the team must plan and design to be able to expose the
interface to developers in the outside world. No exceptions.
6) Anyone who doesn’t do this will be fired.

Mobile Development
HTML5 vs Native
Support multiple languages
Java, Javascript/Node.js, C++
Native
IoS (objective-C) and Android (Java).
Round trip device Emulation.
WP7 (.NET) as a nice to have.
Web
Javascript JQuery Mobile, Dojo mobile,
Sencha. Responsive Design.
Hybrid
HTML5, CSS and JS + deployment
frameworks, Cordova, aka PhoneGap

Design First
New disciplines
user experience,
information
architecture, web
development
Invest in People
Tools enabling
developer/designer/
user interaction and
feedback

API Management is the New SOA
A registry of Microservices
API Throttling for QoS, security
Publish APIs (abstraction, REST)
Document APIs (REST)
Monitor performance
Manage performance - where possible
Elements of SOA, by Dirk Krafzig, Karl Banke, and Dirk Slama

Cloud First: SOA Foundations
Managing The Perils of Success -
unexpected, dramatic load spikes.
Retrofitting security for back end apps and services
not born on the web
Born on the Web development tools and methods
taking advantage of agile, DevOps, NoSQL

16. 16
PaaS Customer-Defined
"PaaS is real. ING Bank serves 9m retail customers. 85%-95% of transactions
are via mobile and internet. In our infrastructure landscape we offer a variety
of services. There is a segmentation of the type of service via the type of app
- we segment data center services, IaaS and Paas.
If we look back to the organisational change initiated 18 months ago. People
make the difference. either in successfully utilising available technology, they
sharpen available services within the framework to better serve the
customer.
We changed the DNA of the people, their attitude and styles.
PaaS means a standardised reliable predictable platform - allowing
developers to shorten the delivery cycle from 80 days to 8 days.
We hire people with the right sparkle in their eyes."
- Mark Willemse, ING Bank

17. 17
Social First
People’s activities have
more meaning in teams
– the sharing economy
Integration with, and
support for, a range of
collaboration tools
Analytics - treating social
data as enterprise data
Social, Local, Mobile

The Age of Context
• Accelerometers
• App usage behaviours
• Location
• Images in context
• Influence patterns
• Facial Recognition
• Emotions
• Health data
• Value of Search data
• Sentiment

Wrap Up
The World is Changing Really Fast – development and deployment needs to change with it.
Mobile First is a cultural shift, underpinned by a variety of related disciplines
Cloud for extensibility – PaaS and IaaS. Standards based.
SOA underpins API Management, which will underpin Mobile First
SOA to prevent internal and external resource contention
Choose dedicated mobile development tools, with a lifecycle focus
- let the IDE track platforms so you don’t have to.
Integration with all back end systems, at scale.
Integrate with transactions, which means the mainframe.
Leverage your existing skills, but augment with new ones. Master Mobile, not just the Mainframe.
