It is clear that although the use of cloud computing , has rapidly increased , cloud computing security is still considered the major issue in the cloud computing environment. Customers do not want to lose their private information as a result of malicious insiders in the cloud. In addition ,the loss of service availability has caused many problems for a large number of customers recently.

ContinuedCloud Computing is in a period of strong growth, but this technology is still has some issues of security and somewhat it is immature. Government Technology Research Alliance (GTRA) research showed that the most common concern about implementing Cloud Computing technology was security.

The real value of cloud computing is that it makes your library related software and data available transparently and everywhere including in latest available smart phone devices.

We are all aware, country like India faced problems like digital divide and off course very low internet bandwidth. So, benefit of new technology can be reached to limited area of educational area.

But definitely, over a period of time Cloud Computing will become the most promising technology in next few years.
