7. Why Cloud Computing? Definition of Cloud Computing “Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.” Source: NIST 2009

9. Why Cloud Computing? Benefits of Cloud Computing? Private Car Rental or Public Vehicle VS Buying it with expensive price Just Rental with cheap price

10. Why Cloud Computing Benefits of Cloud Computing • Reduced Cost • Cloud technology is paid incrementally, saving organizations money. • Increased Storage • Organizations can store more data than on private computer systems. • Highly Automated • No longer do IT personnel need to worry about keeping software up to date.

11. Why Cloud Computing Benefits of Cloud Computing • Flexibility • Cloud computing offers much more flexibility than past computing methods. • More Mobility • Employees can access information wherever they are, rather than having to remain at their desks. • Allows IT to Shift Focus • No longer having to worry about constant server updates and other computing issues, government organizations will be free to concentrate on innovation.

23. Emerging Cloud Mobile cloud • How to develop Mobile Cloud App? • How to reuse the resources on Mobile Device?

24. Media cloud Emerging Cloud CPU: Central Processing Unit, GPU: Graphic Processing Unit Ref) Wenwu Zhu, et. al, “Multimedia cloud computing,” IEEE signal processing magazine, May 2011. • Multimedia processing in a cloud • Multimedia and service heterogeneity • QoS heterogeneity • Network heterogeneity • Device heterogeneity

25. Moving to the media cloud Emerging Cloud Ref) HP, “Moving to the Media Cloud” November 2010 • A shift to the edge • the shift of intelligence away from the network core and toward the network edge • a similar movement of storage and some functionality away from the home and toward the network edge.

26. Emerging Cloud Trend of CC: context-aware computing 26

27. Conclusions and Recommendations • Advantage: • Improved performance • Reduced software costs • Lower computer costs • Instant software updates • Unlimited storage capacity • Increased data reliability • Universal access (services & applications) • Easier group collaboration • Device independence • Disadvantage: • Requires a constant Internet connection • Requires Broadband Infrastructure • Can be slow & Features might be limited • Stored data might not be secure and lost

28. No unique single solution and business modelIdentify objectives and proper position Conclusions and Recommendations
