Conclusion

5. • Cloud Computing is a general term used to
describe a new class of network based
computing over the Internet.
• Data is centralized and stored in a cloud and
can be accessed from anywhere.

7. • It is a service that stores files and allows users
to access them through the Internet.
• Both free and commercial services are
provided.
• Widely used in exchanging files between office
and home and for sharing of data.

9. • Amazon S3(Simple Storage Service)
One of the storage services
provided by Amazon Web Services.
• Dropbox
• SugarSync
• SkyDrive

10. Pogoplug
• Calls itself personal cloud.
• Using pogoplug a user can share USB disks
over the network.
• Large data center is not required since the
data is stored in the users’ files.

11. AjaXplorer
• It is an open source software for Web based
applications.
• Supports several kinds of plugins.
• AjaXplorer is a core of Storage-side
computing.

14. • A public cloud provides services to multiple
customers.
• Public clouds are most often hosted away
from customer premises, and they provide a
way to reduce customer risk and cost by
providing a flexible, even temporary extension
to enterprise infrastructure.

15. • Private clouds may be hosted at a collocation
facility or in an enterprise datacenter.
• They may be supported by the company, by a
cloud provider, of that enterprise itself.

17. Key concept of private cloud.
Super saturation : State of utilizing more logical
resources than physical resources.
Reduces the cost
to 10-50 %.
Resource utilization of a
• conventional not-cloud : 30%
• Cloud : 60%
• Supersaturated cloud : 100%

18. Digital Library System
• It is realized as Web Application based on
AjaXplorer.
• Fess is used to search e-books.
• Fess supports PDF, Office files and Zipped files.

19. Storage-Side Computing
• Digital library system as an example of
Storage-Side computing. Here is an overview
of this:

20. Evaluation
• Effectiveness of storage-side computing:
• SSC is executed in the background.
• Performance of storage-side computing(SSC)
is higher than conventional client-side
computing(CSC)

21. CONCLUSION
• Storage-side computing is a very effective way
of storing data in cloud.
• Here we designed and implemented a digital
library system where more than one user can
use the system simultaneously and all devices
can access the files stored in the online library
