Research School UMIC Workshop on Future Mobile Applications UMIC Workshop on Future Mobile Applications 26 Feb. 2010 Dejan Kovachev Mobile Cloud Computing Dejan Kovachev Informatik 5 (Information Systems) RWTH Aachen University & Bonn-Aachen International Center for Applied Information Technology Lehrstuhl Informatik 5 (Informationssysteme) Prof. Dr. M. Jarke Aachen, Germany I5-Kov-0210-1
  • 2. Research School Agenda Cloud Computing in a Nutshell UMIC Workshop on Future Mobile  Applications 26 Feb. 2010 – Definition Dejan Kovachev – Characteristics – Cloud architecture at I5  Mobile Cloud Computing Concepts – Benefits – Augmented execution – Elastic applications Lehrstuhl Informatik 5 (Informationssysteme) Prof. Dr. M. Jarke (Source: http://lonewolflibrarian.wordpress.com/) I5-Kov-0210-2
  • 3. Research School Trends Pay as you use 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 Lehrstuhl Informatik 5 (Informationssysteme) Prof. Dr. M. Jarke I5-Kov-0210-3
  • 4. Research School UMIC Workshop on Future Mobile Applications 26 Feb. 2010 Dejan Kovachev Lehrstuhl Informatik 5 (Informationssysteme) Prof. Dr. M. Jarke I5-Kov-0210-4
  • 5. Research School Cloud Architecture at I5 UMIC Workshop on Interface Future Mobile Service Applications services Custom Multimedia Storytelling SNA Services … 26 Feb. 2010 Services Services Dejan Kovachev Interface Platform RabbitMQ Message Broker Programming Framework Hadoop, MapReduce HDFS Hbase Sun LDoms Infrastructure Interface Control Domain Start Sun Enterprise T5240 Monitor Stop Load Balancer Database Master Sun LDoms Guest Domain User Manager Lehrstuhl Informatik 5 (Informationssysteme) Security Manager Prof. Dr. M. Jarke I5-Kov-0210-5
  • 6. Research School Mobile Cloud Computing: Concepts An infrastructure where both the data storage and the UMIC Workshop on 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 Prof. Dr. M. Jarke I5-Kov-0210-6
  • 7. Research School 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 Lehrstuhl Informatik 5 (Informationssysteme) Prof. Dr. M. Jarke I5-Kov-0210-7
  • 8. Research School Mobile Web Applications Using web services UMIC Workshop on Future Mobile  Applications 26 Feb. 2010  Is HTML5 a game changer? Dejan Kovachev – 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 Lehrstuhl Informatik 5 (Informationssysteme) Prof. Dr. M. Jarke I5-Kov-0210-8
  • 9. Research School Augmented Execution by Cloning the Smartphone Software UMIC Workshop on Future Mobile Applications (Chun & Mantatis 2009) 26 Feb. 2010 Dejan Kovachev  Examples – Video processing – Anti-virus scan of your phone – Debugging – Running data parallel applications Lehrstuhl Informatik 5 (Informationssysteme) Prof. Dr. M. Jarke I5-Kov-0210-9
