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
