2. What Is Cloud Computing ?
In computer networking, cloud
computing is computing that involves
a large number of computers
connected through a
communication network such as
the Internet. In science, cloud
computing is a synonym
for distributed computing over a
network, and means the ability to run
a program or application on many
connected computers at the same
time.

3. Layers Of Cloud Computing

4. Cloud Software As A Service (SAAS)
• Software services are applications or
components that can be used as an end
application or used as part of a custom
solution .
• SaaS service-model involves the cloud provider
installing and maintaining software in the
cloud and users running the software from
their cloud clients over the Internet. The users'
client machines require no installation of any
application-specific software - cloud
applications run on the server (in the cloud).
• One of the biggest benefits of SAAS is, of
course, costing less money than buying the
application outright.

5. Cloud Platform As A Service (PAAS)
• Platform services offer a ready built
infrastructure and application frameworks that
can be used for building and running
applications.
• PAAS supplies all the resources required to
build applications and services completely from
the internet, without having to download or
install software.
• PAAS services includes application design,
testing and development. Other services
include team collaboration, web service
integration ,database , security scalability ,
storage.

6. Cloud Infrastructure As A Service (IAAS)
• IaaS clouds often offer additional resources
such as a virtual-machine disk image library,
file-based storage, firewalls, load balancers, IP
addresses, virtual local area networks, and
software bundles.
• IaaS-cloud providers supply these resources
on-demand from their large pools installed
in data centres. For wide- area connectivity
customers can use either the Internet
or carrier clouds.
• To deploy their applications, cloud users
install operating-system images and their
application software on the cloud
infrastructure.

7. Cloud Computing Types

8. Cloud Provides

9. Advantages of Cloud Computing
 Lower computer costs.
 Improved performance.
 Reduced software costs.
 Instant software updates.
 Improved document format compatibility.
 Increased storage capacity
 Increased data reliability.
 Universal document access
 Easier group collaboration
 Device independence

10. Disadvantage of Cloud Computing
 Possible downtime - Cloud computing makes
your small business dependent on the
reliability of your Internet connection. When
it's offline, you're offline.
 Security in the Cloud - The other major
issue while in the cloud is that of security
issues. Before adopting this technology, you
should know that you will be surrendering
all your company’s sensitive information to a
third-party cloud service provider. Hence,
you need to make absolutely sure that you
choose the most reliable service provider,
who will keep your information totally
secure.

11. Recent In Cloud Computing
• Backend as a service (BaaS) is a model for providing web
and mobile app developers with a way to link their
applications to backend cloud storage while also providing
features such as user management and integration
with social networking services.
