1. A Conceptual Framework for Provisioning Context-aware Mobile Cloud Services Hyun Jung La and Soo Dong Kim Department of Computer Science Soongsil University Cloud Computing 2010

2. Outlines INTRODUCTION RELATED WORKS COMPUTING MODEL FOR CONTEXT-AWARE CC TYPES OF CONTEXT-BASED SERVICE ADAPTER CONTEXT-AWARE PROVISIONING ARCHITECTURE DETAILED VIEWS OF ADAPTERS FOR SERVICE PROVISIONING CASE STUDY CONCLUSION

3. INTRODUCTION Cloud Computing (CC) –Reusable services Mobile Internet Device (MID) –Sense users’ context –Limited resource

4. INTRODUCTION

5. Challenge –Monitor user contexts and provision right services for the context Contribution –Context-aware affects CC in terms of computing model and overall architecture –Service adapters and specification of the related algorithms

6. RELATED WORKS Context –User context, web service context, resource context Meta-model –Service composition meta-model, context meta-model, combined meta-model Adapter –Context management component, service management component, adaptation management component

7. COMPUTING MODEL FOR CONTEXT-AWARE CC

8. Personalize a service invoked by a sevice consmer Remedy low QoS problems such as faults at service execution time

9. TYPES OF CONTEXT-BASED SERVICE ADAPTER

12. CONTEXT-AWARE PROVISIONING ARCHITECTURE

15. Service Substitutor Functionality: This adapter is to bind different services for the functionality for the current context

17. Service Interface Adapter Functionality: This adapter is to resolve the interface incompatibility between callers and callees

19. Service Component Substitutor Functionality: This adapter is to replace a service component with a compatible service component adapted to the given context.

21. Service Rerouter Functionality: This adapter is to modify the location of a service component which gets invoked, and to reroute the invocation to the new location.

23. CASE STUDY Travel Assistant: Provide the current locaiton information of the user

24. CONCLUSION A potential happy marriage between CC and MID Resource limitation of MID can besolved A conceptual framework (context, gap, cause, adapter)
