Trends Pay as you use
– Costs are based on consumption (CPU cycles, storage)– Not having to buy and configure new equipment– No software/hardware maintenance
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

Research SchoolMobile Cloud Computing:
Concepts
An infrastructure where both the data storage and the data processing happen outside of the mobile device
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
– The developer doesn’t care about partitioning the app

Research SchoolMobile Cloud Computing:
Benefits
Cloud storage– Local storage good for performance
– 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

Mobile Web Applications
Using web services Is HTML5 a game changer?
– AppCache, database and offline working– Geolocation API– 2 way communication with the server– Canvas, drag and drop– Web Workers
An example:– Google Voice on the iPhone

Summary Cloud Computing comes in many shapes and sizes from
infrastructure, to middleware, to entire platforms– On-demand– Elastic scalability– Usage-metered
The data storage and processing happen outside of the mobile device– Seamlessly integrated within the cloud
Activities– UMIC Virtual Campfire Scenario– Mobile Cloud Computing Lab – SS10– Round Table “Cloud Computing” by T-Com at CeBIT 2010
