2. CLOUD COMPUTING
“Cloud Computing” is a new and promising paradigm
delivering IT services as computing utilities. As Clouds are
designed to provide services to external users, providers need to
be compensated for sharing their resources and capabilities. In
this Presentation, we have proposed architecture for market-
oriented allocation of resources within Clouds. We have also
presented a vision for the creation of global Cloud exchange for
trading services.

3. “Cloud computing” is an umbrella term used to refer to
Internet based development and services.
Cloud computing is the use of computing resources
(hardware and software) that are delivered as a service
over a network (Typically the Internet). The name comes
from the use of a cloud-shaped symbol as an abstraction
for the complex infrastructure it contains in system
diagrams. Cloud computing entrusts remote services with
a user's data, software and computation.

5. “Cloud Services”
 Infrastructure as a Service (IAAS)
 Platform as a Service (PAAS)
 Software as a Service (SAAS)

7. Infrastructure as a Service (IAAS)
 Infrastructure-as-a-Service(IAAS) like Amazon Web
Services provides virtual servers with unique IP
addresses and blocks of storage on demand.
Customers benefit from an API from which they can
control their servers. Because customers can pay for
exactly the amount of service they use, like for
electricity or water, this service is also called utility
computing.

8. Platform-as-a-Service(PAAS)
 Platform-as-a-Service(PAAS) is a set of software and
development tools hosted on the provider's servers.
Developers can create applications using the provider's
APIs. Google Apps is one of the most famous Platform-
as-a-Service providers. Developers should take notice
that there aren't any interoperability standards
(yet), so some providers may not allow you to take your
application and put it on another platform.

9. Software-as-a-Service (SAAS):
 Software-as-a-Service (SAAS) is the broadest market.
In this case the provider allows the customer only to
use its applications. The software interacts with the
user through a user interface. These applications can
be anything from web based email, to applications like
Twitter.

10. Types of Cloud
 Private Cloud
 Public Cloud

12. Private Cloud
 Private clouds describe offerings that deploy cloud
computing on private network. it consists of
application or virtual machines in a company's own set
of hosts. they provide the benefits of utility
computing, shared hardware costs the ability to
recover from failure and the ability to scale up or down
depending upon demand.

13. Public Cloud
 A Public cloud is one based on the standard cloud
computing model, in which a service provider makes
resources, such as applications and storage, available to
the general public over the Internet. Public cloud services
may be free or offered on a pay-per-usage model .

14. Hybrid Cloud
 Hybrid cloud is a composition of two or more clouds
(private, community, or public) that remain unique
entities but are bound together, offering the benefits
of multiple deployment models. It can also be defined
as multiple cloud systems that are connected in a way
that allows programs and data to be a moved easily
from one deployment system to another.

15. “Server Virtualization”

17. “Virtualization” is a method of running multiple independent virtual
operating systems on a single physical computer. Virtualization, in
computing, is the creation of a virtual (rather than actual) version of
something, such as a hardware platform, operating system, a storage
device or network resources. A virtual organization is a collection of
people and resources that work in a coordinated way to achieve a
common goal. To use grid facilities, any user must subscribe to a
virtual organization as a member. Each people or resource can be a
member of more virtual organizations at the same time and each
virtual organization can contain people or resources belonging to
different administration domains.

18. “Server Virtualization” is the masking of server resources, including
the number and identity of individual physical servers, processors, and
operating systems, from server users. The server administrator uses a
software application to divide one physical server into multiple
isolated virtual environments. The virtual environments are sometimes
called virtual private server. Virtual machines are based on the
host/guest paradigm. Each guest runs on a virtual imitation of the
hardware layer. This approach allows the guest operating system to
run without modifications. It also allows the administrator to create
guests that use different operating systems.

19. Future Opportunity
 TOWARDS GLOBAL CLOUD ECOSYSTEMS
 NEW BUSINESS MODELS AND EXPERT SYSTEMS
 GREEN IT
 OPEN SOURCE CLOUDWARE

20. Conclusion
 Today, the latest paradigm to emerge is that of “Cloud
Computing” which promises reliable services delivered
through next-generation data centers that are built on
virtualized compute and storage technologies. Consumers will
be able to access applications and data from a “Cloud”
anywhere in the world on demand. The consumers are assured
that the Cloud infrastructure is very robust and will always be
available at any time.
