 A process of translating the business vision and

current and future objectives
 Zachman defines an Enterprise Architecture as...
 ..."that set of descriptive representations (i.e. ‘models’)
that are relevant for describing an Enterprise such that it
can be produced to management’s requirements
(quality) and maintained over the period of its useful life
(change)"

17. Cross platform pros & cons
Pros PhoneGap
Appcelerator
 One code base MoSync
Service2Media
Cons RhoMobile
Mono
 Frameworks not stable Etc.
 Performance issues
 Code platform specific is still needed
 Customizing standard component is still difficult
 Unique skill-set combination (think maintenance
costs)
13/8/12

18. Platform considerations
 High diversity of enterprises
 Target number of supported platforms is
1, might be 2-3
 Smartphones, tablets or both
 Tablets help the adoption of mobile in the
enterprise targeting employees as users

19. Ready to start architecting
your mobile app for enterprise?
Understand, analyze and think about the following
 Business goals/vision
 Infrastructure: AS IS vs possibility to change
 Service Oriented Architecture (SOA) ?
 Bring your own device (BYOD)
 Mobile device management (MDM)
 Security
13/8/12

20. Does SOA help
mobile enterprise apps?
Mobile clients Presentation (WEB app/Portal)
Services Composite Services
and
Components

21. BYOD – Bring your own device
What is BYOD?
 Bring personal devices to the workplace
 Devices = smartphones, tablets and laptops
 Use corporate network
Security challenges (i.e. security policies, cloud)

22. MDM – Mobile Device Management
Enterprise needs control, MDM software
secures, monitors, manages mobile devices
Features Providers
• Over the air updates • AirWatch
• Remote configuration and • Sybase
provisioning • MobileIron
• Security • Symantec
• Backup/Restore • Apple
• Remote Lock and Wipe • Etc.
• Apps installation
• Remote control and
administration
• Etc.
