Goals For Today:

1

• Defining “mobile infrastructure”• Quick mobile technology overview & history• Mobile infrastructure in the campus context: now &

future• Crossing the infrastructure-application boundary

Infrastructure defined:

2

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.

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/notebook12.4% have tablet (10% plan to buy)11% have eReader (e.g. Kindle)61% have non-internet mobile phone54% have smartphone (16% plan to buy)

Trends vs Hype for Mobile Use

11

Economic Drivers

Google & Apple: App stores=control of revenue

Apple: a hardware company first:ipod->iphone->ipad->??

Carriers: $$ data plans, infrastructure costs

Trends vs Hype in Mobile Devices

12

“Enterprise” Mobile Considerations

13

New devices, new consumption patterns

14

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.

The Past and Future of Berkeley-owned mobile infrastructure

1)Access: availability and capacity2)Landlines vs. Mobile3)Security4)Innovation: policy; approaches & economic realities

Applications & Mobile Infrastructure

16

Good advice for mobile: “Don’t overthink it.”

Mobile infrastructure = IT infrastructureMobile security = IT securityMobile 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
