UMIC Workshop
on
Future Mobile

– Costs are based on consumption (CPU cycles, storage)
Applications
26 Feb. 2010
– Not having to buy and configure new equipment
– No software/hardware maintenance
Dejan Kovachev
 Large data volumes
– US American consume 34 GB per day (2009)
 Smartphones are massively used
– Possibilities for new complex applications
– But limited hardware
 Broadband mobile internet

Future Mobile 
data processing happen outside of the mobile device
Applications
26 Feb. 2010
Dejan Kovachev  Part of the cloud computing spectrum
– Consider seamless and transparent integration between
computers, the Web and phones
 Integration with other services and sensor data
 Illusions of the architecture (Chun & Mantiatis 2009)
– Mobile user has a much more powerful,
feature-rich device
Lehrstuhl Informatik 5
(Informationssysteme) – The developer doesn’t care about partitioning the app

Mobile Cloud Computing:
Benefits
Cloud storage
UMIC Workshop
on
Future Mobile 
Applications
26 Feb. 2010 – Local storage good for performance
Dejan Kovachev
– But if battery goes empty, or phone lost
– Data reliability & data availability
 Cloud processing
– Off-loading intensive computations
– Local vs. remote processing
 Scalable resources on-demand
 Less complexity
