4. Cloud computing is simply a buzzword used
to repackage grid computing and utility
computing, both of which have existed for
decades.

5. Cloud computing is Internet-based computing, whereby shared resources, software
and information, are provided to computers and other devices on-demand, like the
electricity grid.
-- Wikipedia

7. - Reduction of costs - unlike on-site hosting the price of deploying applications in the
cloud can be less due to lower hardware costs from more effective use of physical
resources.
- Universal access - cloud computing can allow remotely located employees to
access applications and work via the internet.
- Up to date software - a cloud provider will also be able to upgrade software
keeping in mind feedback from previous software releases.
- Choice of applications - This allows flexibility for cloud users to experiment and
choose the best option for their needs. Cloud computing also allows a business to
use, access and pay only for what they use, with a fast implementation time
- Flexibility - cloud computing allows users to switch applications easily and rapidly,
using the one that suits their needs best. However, migrating data between
applications can be an issue.

the client via the Internet from a third party
service provider.
Example: Amazon

11. It is a combination of services provided by the Private and
public cloud
Example:

12. • Private Cloud: These services are managed and
provided within the organization. There are less
restriction on network bandwidth, fewer security
exposures and other legal requirements compared
to the public Cloud.
Example: HP Data Centers
