Cloud computing allows users to access software and store documents on remote servers rather than a personal computer. If a computer crashes, files are still accessible from other devices through internet connections to these remote servers. Cloud services deliver computing power, infrastructure, applications, business processes, and collaboration tools to users on demand from any location via the internet. Cloud models include public clouds where infrastructure is run by external providers, private clouds where a company manages its own infrastructure, and hybrid clouds that combine internal and external storage of different types of data.
4. With cloud computing, the s/w programs one use
aren’t run from one’s personal computer, but are
rather stored on servers accessed via the
internet.
If a computer crashes, the s/w is still available
for others to use. Same goes for the documents
on create; they are stored on a collection of
servers accessed via the internet.
Cloud Computing model isn’t PC-centric, its
Document-Centric.

The Cloud in cloud computing provides the mean
through which everything- from computing power
to computing infrastructure, applications, business
processes to personal collaboration – can be
deliver to you as a service wherever n whenever
you need.
15. PUBLIC CLOUD
We have focused on cloud service providers
whose data centers are external to the users
of the service (businesses or individuals).
These clouds are known as public clouds—both
the infrastructure and control of these clouds
is with the service provider.
16. PRIVATE CLOUD
A variation on this scenario is the private cloud.
Here, the cloud provider is responsible only for
the infrastructure and not for the control. This
setup is equivalent to a section of a shared data
center being partitioned for use by a specific
customer. The private cloud can offer SAAS,
PAAS, or IAAS services, though IAAS might
appear to be a more natural fit.
17. A hybrid cloud involves data centers storing secure
and important data on the enterprise premises and
less important data to be stores at a remote
location in the cloud. So it is a mixture of public
and private cloud that yields the most benefit.
