Infrastructure as a Service (IaaS) is a provision
model in which an organization outsources the
equipment used to support operations,
including storage, hardware, servers and
networking components.

20. Cloud 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.
