Goals For Today:
•
•
•
•
Defining “mobile infrastructure”
Quick mobile technology overview & history
Mobile infrastructure in the campus context: now & future
Crossing the infrastructure-application boundary
1
Infrastructure defined:
The term IT Infrastructure is defined in ITIL v3 as
combined set of hardware, software, networks, facilities, etc.
(including all of the Information Technology), in order to
develop, test, deliver, monitor, control or support IT
services. Associated people, Processes and documentation
are not part of IT Infrastructure.

Mobile Devices at UC Berkeley
What we have at UC Berkeley today: Devices
(from UC Berkeley / California Digital Library 2010 Community Mobile Survey)
67% have desktop (declining)
95% have laptop/notebook
12.4% have tablet (10% plan to buy)
11% have eReader (e.g. Kindle)
61% have non-internet mobile phone
54% have smartphone (16% plan to buy)

Trends vs Hype for Mobile Use
Economic Drivers
Google & Apple: App stores=control of revenue
Apple: a hardware company first:
ipod->iphone->ipad->??
Carriers: $$ data plans, infrastructure costs
11
Trends vs Hype in Mobile Devices
12
“Enterprise” Mobile Considerations
13
New devices, new consumption patterns
A smartphone generates 24 times the
mobile data traffic of a conventional
wireless phone, and the explosively
popular iPad and similar tablet devices
can generate traffic comparable to or
even greater than a smartphone.
AT&T’s mobile data volumes surged by
a staggering 8,000% from 2007 to
2010, and as a result, AT&T faces
network capacity constraints more
severe than those of any other
wireless provider.

Applications & Mobile Infrastructure
Good advice for mobile: “Don’t overthink it.”
Mobile infrastructure = IT infrastructure
Mobile security = IT security
Mobile applications = IT applications
• So What’s Important?
•
•
•
•
•
•
•
Meeting user needs by accommodating form factor changes
Realize added value by addressing opportunities of the mobile context
Broad mandate for mobile use-cases (“mobile first”)
Institutions addressing implications of device consumerization
Innovation vs Standardization in a rapidly evolving landscape
Mobile frameworks, HTML5 vs. Native
Compression and mobile performance
