4. The terms "cloud computing" and "working
in the cloud" refer to performing computer
tasks using services delivered entirely over
the Internet
(The "cloud" refers to the Internet and was
inspired by technical flow charts and
diagrams, which tend to use a cloud symbol
to represent the Internet.)
8. Uses of cloud computing
1.help to use application without installing.
2.access any personal file at any computer
with the internet access.
3.this technology allow much more efficient
computation by centralizing storage,
memory processing and bandwidth.
9. Working of cloud computing
Cloud computer works by hosting your information on
computers ‘out there’ ‘in the cloud’. The cloud is basically a
batch of computers called data centers or servers that hold
your information (files,images,videos,etc) and can be
located anywhere. You’re working in a cloud because you
don’t have to store software or files on your own
computer.
10. Characteristic of cloud computing
1:On demand self service: computer services such as
email,applications,networks or server services can be
provided without requiring human interaction with each
service provider.
2:Broad network access: cloud capabilities are available over
the networks and accessed through the standard mechanism that
promote use by heterogeneous thin and thick client platform such as
mobile phone,laptops.PDAs.
3:Resource pooling: the providers computing resources are
pooled together to serve multiple consumers using multiple-tenant
model, with different physical and virtual
resources dynamically assigned and reassigned according to
consumer demand.
11. 4:Rapid elasticity: cloud service can be rapidly and
elastically provisioned ,in some case automatically ,to
quickly scale out and rapidly released to quick scale in.
To the
consumer, the capabilities available for provisioning
often appear to be unlimited and can be purchased in
any quantity at any time.
5:Measure service: Cloud computing resource
usage can be measured, controlled, and
reported providing transparency for both the provider
and consumer of the utilized service
12. Platform
Cloud platform services or Platform
as a Service (PaaS)
" deliver a stack as a service, often
consuming
cloud infrastructure and sustaining
cloud applications. It facilitates deployment
of applications without the cost and
complexity of buying and managing the
under lying hardware and software layers.
Computing platform and/or solution
13. Infrastructure
cloud infrastructure services or “infrastructure as
a service{laas}”delivers computer infrastructure,
typically a platform virtualization environment,
as a service. rather than purchasing
servers,software,data center space or network
equipment client instead by those resources as a
fully outsources services…..
14. Application
Cloud application services or "Software
as a Service(SaaS)
" deliver software as a service over the
Internet, eliminating the need to install and
run the application on the customer's own
computers and simplifying maintenance
and support.

16. Types of cloud computing
1.Public cloud: Public cloud or external cloud is a
metered service similar to public utility provided by
the vendors via web applications or web services
where the location of the infrastructure is invisible to
the customers and it is shared between the
organizations. The numbers of small and medium
sized companies acquiring external cloud are rising for
its tariff lower than the private cloud.
2.Private cloud: Private cloud or internal cloud
is a private network in the cloud externally or within
the premises where the customers do not share their
with other organization.
17. expensive and more secure than pubic cloud.
3.Hybrid cloud: hybrid cloud is the combination of both
public and private cloud based upon the criticality of
applications used where the organizations may have
multiple public and private providers.
4.Community cloud: Community cloud is a network
shared by the same type of organizations. The National
Institute of Standards and Technology (NIST) say
Community cloud is a cloud infrastructure which is
shared by several organizations and supports a specific
community that has shared concerns (e.g., mission,
security requirements, and policy and compliance
considerations). It may be managed by the
organizations or a third party and may exist on premise
or off premise.

19. Advantages of cloud computing
1:cost efficient: cloud computing is probably the most cost
efficient to use,maintane and upgrade Traditional desktop
software costs companies a lot in terms of finance. Adding
up the licensing fees for multiple users can prove to be
very expensive for the establishment concern.
2:Almost unlimited storage: storing information in the
cloud give you almost unlimited capacity. Hence you no need to
worry about running out of storage space and increasing current
storage availability
3:Backup and recovery: since all your data stored in cloud ,
backing it up and restoring is same is relatively much easier than
storing on the same physical device.
20. 4:automatic software intigration:In the cloud,
software integration is usually something that occurs
automatically. This means that you do not need to take
additional efforts to customize and integrate your
applications as per your preferences. This aspect usually
takes care of itself. Not only that, cloud computing
allows you to customize your options with great ease.
5:Easy access to information: once you register
yourself to cloud, you can access the information from
anywhere, where there is an internet connection.
21. Disadvantages of cloud computing
1:security & privacy:
The biggest concerns about cloud computing
are security and privacy. Users might not be
comfortable handing over their data to a third party.
This is an even greater concern when it comes to
companies that wish to keep their sensitive information
on cloud servers.
2.Dependency (loss of control):Quality problems
with CSP(Cloud Service Providers).No influence on
maintenance levels and fix frequency when using cloud
services from a CSP.
3.Cost:While in the long run, cloud hosting is a lot
cheaper than traditional technologies, the fact that it’s
22. currently new and has to be researched and improved
actually makes it more expensive. Data centers have to
buy or develop the software that’ll run the cloud, rewire
the machines and fix unforeseen problems . This makes
their initial cloud offers more expensive.
4.Decreased flexibility: this is only a temporary
problem (as the others on this list), but current
technologies are still in the testing stages, so they don’t
really offer the flexibility they promise.
5.Knowledge :More and deeper knowledge is
required for implementing and managing SLA contracts
with CSP’s ,Since all knowledge about the working of
the cloud (e.g. hardware, software, virtualization,
deployment) is concentrated at the CSP, it is hard to get
grip on the CSP.
23. Conclusion:
computing has tremendous potential to benefit
businesses, industries, and entire economies, but
substantial challenges stand in the way. Our study
has taken the first step: defining potential actions
for industry and governments to consider in order
to accelerate cloud adoption and generate benefits
for all stakeholders – individuals, businesses,
governments, and society as a whole
