1.1.Introduction(Definitions, Ideas & Applications)
• Cloud Computing means storing and accessing data and
programs over the Internet instead of your computer's
hard drive.
• Cloud Computing is a new approach that reduces IT
complexity by leveraging the efficient pooling of on-
demand, self-managed virtual infrastructure, consumed as
a service
• Main Idea-Save the time of reader by providing
information anytime anywhere.
• Main idea- More efficient and speedy distribution of
library services with lower cost
• Applications in which cloud computing is used-Social
Networking sites, E-mail sites, Search Engines.
Components of Cloud Computing
• Distributed Servers: server acts as if they are working
next to each other, Central Server, Datacenters
• Central Server: Administers the system such as
monitoring traffic, client demands to ensure everything
runs smoothly.
• Datacenters: collection of servers where application is
placed and is accessed via internet.
• Client Computers: Clients are the device that the end user
interact with cloud.

1.2.Introduction(History)
• Concept evolved in 1950(IBM) called RJE (Remote Job
Entry Process).
• Web 2.0-being the most recent evolution. However, since
the internet only started to offer significant bandwidth in
the nineties, cloud computing for the masses has been
something of a late developer.
• Arrival of Salesforce.com in 1999 pioneered the concept
of delivering enterprise applications via a simple website.
• The next development was, a suite of cloud-based
services including storage, computation and even human
intelligence through the Amazon Mechanical Turk
• In 2006, Amazon launched its Elastic Compute cloud
(EC2) as a commercial web service that allows small
companies and individuals to rent computers on which to
run their own computer applications.
• Google Enterprise based apps-Another big milestone
came in 2009
• Microsoft and Google The most important contribution to
cloud computing has been the emergence of "killer apps"
from leading technology giants such as Microsoft and
Google.

Features Description
“no-need-to-know”
The “no-need-to-know” in terms of the underlying details of infrastructure, applications interface with
the infrastructure via the APIs.
“flexibility and elasticity”
It allows these systems to scale up and down at will utilizing the resources of all kinds: CPU, storage,
server capacity, load balancing, and databases
“pay as much as used and
needed
The “pay as much as used and needed” type of utility computing and the “always on!, anywhere and
any place” type of network-based computing. Cloud are transparent to users and applications, they can
be built in multiple ways : branded products, proprietary open source, hardware or software, or just off-
the-shelf PCs.
Infrastructure-less Cloud computing enables companies and applications, which are system infrastructure dependent, to be
infrastructure-less.

Clouds
Description
Private cloud The cloud infrastructure is operated
solely for an organization. It may be
managed by the organization or a third
party and may exist on premise or off
premise.
Public cloud Mega-scale cloud infrastructure is
made available to the general public
or a large industry group and is owned
by an organization selling cloud
services.
Hybrid cloud The cloud infrastructure is a
composition of two or more clouds
(private or public) that remain unique
entities but are bound together by
standardized or proprietary technology
that enables data and application
portability

4.SWOT: Advantages and Benefits.
# Advantages Brief explanation
1 Improved document format
compatibility
You do not have to worry about the documents you create on your machine being
compatible with other users' applications or OSs
2 Easier group collaboration Multiple users can collaborate easily on documents and project
3 Instant software updates When the application is web-based, updates happen automatically
When you access a web-based application, you get the latest version without needing
to pay for or download an upgrade..
4 Increased data reliability If your personal computer crashes, all your data is still out there in the cloud, still
accessible
5 Universal document access Documents stay in the cloud, and you can access them whenever you have a computer
and an Internet connection and Documents are instantly available from wherever you
are…
6 Latest version availability The cloud always hosts the latest version of your documents as long as you are
connected, you are not in danger of having an outdated version
16

# Advantage Brief explanation
7 Lower
computer costs
You pay for what you use You do not need a
high-powered and high-priced computer to run
cloud computing's web-based applications.
8 No Processing
Power and
HardDisk
Since applications run in the cloud, not on the
desktop PC, your desktop PC does not need the
processing power or hard disk space demanded
by traditional desktop software.
9 Less
Expensive PC
can work
When you are using web-based applications,
your PC can be less expensive, with a smaller
hard disk, less memory, more efficient
processor..
10 No softwares
needed
In fact, your PC in this scenario does not even
need a CD or DVD drive, as no software
programs have to be loaded and no document
files need to be saved
17

5.SWOT:Weaknesses/Potential Problems
# Disadvantage (weakness) Why? Provide clear justification here.
1 Does not work well with
low-speed connections
Similarly, a low-speed Internet connection, such as that found with dial-up services,
makes cloud computing painful at best and often impossible.
2 Features might be limited This situation is bound to change, but today many web-based applications simply are
not as full-featured as their desktop-based applications.
3 Can be slow Even with a fast connection, web-based applications can sometimes be slower than
accessing a similar software program on your desktop PC.
4 Stored data might not be
secure
With cloud computing, all your data is stored on the cloud. It can be possible that
unauthorised users gain access to your confidential data
5 Stored data can be lost On the off chance that your data goes missing, you have no physical or local backup.
Put simply, relying on the cloud puts you at risk if the cloud lets you down.
6 General Concerns Each cloud systems uses different protocols and different APIs may not be possible to
run applications between cloud based systems
18

Cont’d
# Disadvantage (weakness) Why? Provide clear justification here.
7 Limit flexibility and innovation: Security
could prove to be a big issue:
The others are likely become the bigger Internet companies like Google and
IBM, who may monopolise the market. Some argue that this use of
supercomputers is a return to the time of mainframe computing that the PC
was a reaction against.
8 Safety It is still unclear how safe out-sourced data is and when using these services
ownership of data is not always clear.
9 Requires a constant Internet connection Cloud computing is impossible if you cannot connect to the Internet. Since
you use the Internet to connect to both your applications and documents, if
you do not have an Internet connection you cannot access anything, even your
own documents. A dead Internet connection means no work and in areas
where Internet connections are few or inherently unreliable, this could be a
deal-breaker.
10 There are also issues relating to policy and
access
If your data is stored abroad whose policy do you adhere to? What happens if
the remote server goes down? How will you then access files? There have
been cases of users being locked out of accounts and losing access to data.

8. 1.Our Own Conclusion.
• Real business value by Cloud computing can be realized
by customers of all sizes. Cloud solutions are simple to
acquire, don’t require long term contracts and are easier
to scale up and down as needed
• Scaling is easy and fast If we do everything over cloud.
• No need of installing memory consuming software and
make things cumbersome to do. We can develop things by
using online cloud based software's using data stored on
cloud
• It will reduce complexity i.e. whatever we will do on
cloud will get eventually reflect at your client side.
• Even though Cloud computing is good but for low
internet speed. It's like crying on and having nothing in
hands.
• Security Compliance and Monitoring is achievable with
careful planning and analysis
• Our cloud data is liable to access by non authorized
users and therefore can be hacked or leaked easily but if
security issues and challenges will get solve It’s the best
computing for all business kinds.
 The importance of cloud computing can be seen in such a
way that library related software and data available
transparently and everywhere including in latest
available smart phone devices.
 Some countries like India faced problems like digital
divide and of course very low internet bandwidth. So,
benefit of new technology can be reached to limited area
which is not really cool.

8.2.Our Own Recommendations
A)Should companies and businesses invest financial and human resources, deploy and use Cloud Computing?
There are some PROs and CONs of companies and businesses investing financial and human resources, deploy and use
Cloud Computing.
You want reliability and availability assurances, tech support assurances, whatever you need by taking care of some factors:
1. Choose your cloud providers wisely
2.Make sure you have good contracts in place with them.
3.Make sure You could own your data, and be able to download that data at any time.
4.Make sure You want assurances that your data will not disappear if the cloud provider goes out of business or discontinues
your service
26

8.2.1.Our Own Recommendations(Part-A)
A)Should companies and businesses invest financial and human resources, deploy and use Cloud Computing?
Answer is Yes because computing is cheaper because of economics of scale.
Answer is Yes because Cloud providers have the potential to be far more secure than the corporations whose data they are holding. It is the
same economies of scale. For most companies, the cloud provider is likely to have better security than them by a lot.
Answer is No because we will have limited customization options.
Answer is No because of security & Complexity. This is not an idle concern. IT security is difficult under the best of circumstances, and
security risks are one of the major reasons it has taken so long for companies to embrace the cloud. And here it really gets complicated.
Answer is No because the cloud provider might not meet your legal needs. You might have regulatory requirements that the cloud provider
cannot meet. Many foreign companies are thinking twice about putting their data inside America, because of laws allowing the government to
get at that data in secret.
Answer is No because Criminals already steal far more credit card numbers than they can monetize; they are more likely to go after the
smaller, less-defended networks. But a national intelligence agency will prefer the one-stop shop a cloud provider affords. That is why the
NSA broke into Google's data centers. Finally, the loss of control is a security risk.
Finally our conclusion is :
As a business, you need to weigh the benefits against the risks. And that will depend on things like the type of cloud service you're
considering, the type of data that's involved, how critical the service is, how easily you could do it in house, the size of your company and the
regulatory environment, and so on.
27

8.2.2Our Own Recommendations(Part-B)
B)Should we (CS/IS Department) recommend Cloud Computing for active use in CS/IS curricula, for example, as a separate
DIS or Advanced Topics course?
Answer is Yes because Students should learn Cloud computing as a part of their curriculum because of following reasons:
1.Cloud computing is the vast field and future of computing.
2. Specialization and outsourcing make society more efficient and scalable, and computing isn't any different.
3.There are regions of extensive research for students in this field like :
loss of control, new and unquantifiable security risks, and -- above all -- a lack of trust. It is not enough to simply discount them, as
the number of companies not embracing the cloud shows. It is more useful to consider what we need to do to bridge the trust gap.
4.Students could contribute to overcome the challenges and suggest their solutions to make this field more and more secure.
5.Cloud experts are in demand now a days so students can have great career opportunities if they learn this they could pursue
profession in cloud computing.
