Abstract
Beauty of Cloud Computing is its Simplicity. A lot of visions exist for Cloud computing terminology. Here is a re-collection of facts
about cloud computing. Basic approach for understanding CC technology Interview of cloud technology as well as proposal for
further empirical work in modeling cloud computing technologies

1. INTRODUCTION
Cloud Computing technology is On-demand network access
to a shared pool of computing resources. This access is
provided when online from a web-browser. The motive of
such access is to provide user a convenient work-place.
Cloud computing is a technology introduced to reduce
„Headache‟ on user-side.
Cloud computing is combination of two terms: Cloud &
Computing. Cloud is the Network. A network is a bulk of
thousands of users. These users may or may not be
connected. If they are connected, there will be one of model
formed, discussed further. The cloud also consists of Server
& a Database. Server is also known as Cloud-Provider;
while Database is a collection of user-details and
applications to be worked upon by users. Computing is the
term used for services of cloud.
Another main defining characteristic of cloud computing
technology is concluded in a phrase as
“User pays what he need”
2. OBJECTIVES
Our main objectives for the research are as follows:
 To understand the current state of knowledge in a
research area
o What is known/generally accepted
o What questions remain unanswered
o Where do conflicting results exist
 To show how the current research project is linked
to previous research (cumulative tradition).
 To summarize and synthesize previous research
 To critically analyze previous research: strengths
and weaknesses
 To learn from others and stimulate ideas
3. UNDERSTANDING ORIGIN OF CC
It is observed that Peer-to-peer computing cloud not be
introduced in Grid computing. So, Cluster computing was
collaborated with Client-Server computing, resulting into
emerging Cloud Computing.
Cloud computing components are infrastructure, softwares,
applications, business and humans (server/client). In other
words,
CC  Components + Services
Services provided are Easy-to-use, Fast-to-use and Ready-
to-use.
4. KEY FEATURES OF CC
A. No efforts from user side.
Installation, configuration, testing, running, securing,
updating are cloud provider headache not users‟.
B. Zero Maintenance for Client.
Web-store i.e. CC applications are maintained by cloud-
provider.
C. Open browser  login  customize application
 start using service
D. Least investment.
Enterprise pays for infrastructure and environment set up.
E. Reliable network.
F. Customizations preserved during upgrades
G. Flexibility in data manipulation
H. Fast application deployment.
I. Built-in security provided.

5. BASIC PARAMETERS TO ESTABLISH CC
Before establishing cloud computing, some parameters are
decided to be covered. Above of all is empowering basic
customizations and integrations. Cloud computing should
also support Real-time reporting of failures. The technology
is categorized into sharing models.
As the cloud users exist globally, so multiple languages and
currency payments facility must also available.
Finally, comes the part of Security and Privacy. It is
managed by several strategies. It is the most basic property
of cloud computing technology, as success of large
Database storage establishment relies on security and
privacy rule-book only.
Ease-of-use decides level of cloud provided by any
enterprise.
6. CONCLUDING DEFINITIONS FOR CC
On-demand Self-service
It is stated that decisions for automated payments, resources
procured and disposed of by customer himself.
Resource Pooling
By using Virtualization technique, cloud provider pools
the computing resources. It is the best way to attract
clients towards particular cloud.
Broad network access
Some interfaces are standardized so as to make services
available over the network.
Calculated Services
Customer payment mode is available, which is based on
criteria of Pay-per-use.
7. MODELLING OF CLOUD COMPUTING
After years of debates, the resulted models categorized for
cloud technology are:
1) Delivery Models
a) Software-As-A-Service (SAAS)
b) Platform-As-A-Service (PAAS)
c) Interface-As-A-Service (IAAS)
 SAAS is a model where user can control some of
application configurations only.
 PAAS model is defined when user can control
deployment platform & some environment
configuration.
 IAAS model is where user can control Operating
System, storage and some networking components.
2) Development Models
d) Commercial cloud
e) Scientific cloud
f) Business cloud
 Commercial cloud is established where individual
use per cloud exists.
 Scientific cloud is based on Use of cloud for
particular field.
 Business cloud as per by name, relies only for
business strategies and development purposes.
There are more development models being categorized day
by day.
3) Deployment Models
g) Public cloud
h) Private cloud
i) Community cloud
j) Hybrid cloud
This is better way to categorize development models, as
these are based on Client-categorization.
Characteristics describing deployment models are:
who manages, who owns, where located & who
accesses.Table 1 shows a summary for 4 primary cloud
deployment models. This summary is not a categorization, it
is for initial modeling purposes.
 Public clouds are defined over very large scale. As per by
name shows, it is for general public so such clouds are
considered to be Untrusted. The users are not meant to be
member of organization providing cloud.
 Private clouds are established for single enterprise. Here the
users are considered to be trusted as they are tied into some
contractual agreement done before being member. “The
physical infrastructure may be owned by and/or physically
located in the organization‟s datacenters (on-premise) or
that of a designated service provider (off-premise) with an
extension of management and security control planes
controlled by the organization or designated service
provider respectively” (Bardin, Callas, Chaput et al. 2009)
 Community clouds have deployment characteristics similar
to Private clouds. Its users are also considered to be trusted.
But the difference come where the clients are divided into
some Specific groups called Communities.
 Hybrid clouds are combinations of public, private
or/and community clouds. These are connected to each other

through gateway. The highlight feature of hybrid is that
untrusted access to resources is strictly prohibited.
8. EXPLORING CLOUD COMPUTING TOOLS
AND PRODUCTS
Although Cloud computing technology is provided by
almost all corporate enterprises, still some of them are listed
as below:
IBM Blue-cloud Platform
Microsoft Live Meeting
Microsoft Share Point Online
TPlatform (TFS
Hadoop, VMWare, Eucalyptus
GoogleFileSystem (GFS)
KosmosFS
...and many more.
The reputed companies which provide online facility of
cloud computing are:
Google, Yahoo, IBM, Oracle, HP, HCL, TCS, Hitachi,
Netmagic, Novell VMWare, Ramco, Cognizant, CRMOrbit,
ZOHO.
TrendMicro, CSS and ZScaler are famous industries to
provide Cloud Security environment.
Amazon is one of leading company in Cloud Computing
providers. Amazon offers Virtual Private Clouds, that use
public cloud infrastructure in a private manner, connecting
the public cloud resources to the organizations internal
network (Amazon 2009b).
CONCLUSIONS
This paper gives a conclusion of our Review work on Cloud
Computing. CC is the latest technology used to provide
reliable platform for customers. No need to invest huge
money in setting up infrastructure. Enterprise and
companies pay for services based on client Usage. It‟s kind
of „money-back-guarantees‟. User has no worry about
Resource Management. Flexibility in data manipulation is
available. Collaboratively working on common projects.
Privacy and security satisfaction
Cloud computing preserves all customizations even during
Upgrades. Cloud Computing technology has one primary
demerit, it is that the OFFLINE access for CC is still not
possible.
FUTURE WORK
The paper gave brief view about all sorts of Cloud Models.
In future, deployment models can be introduces on basis of
Enhancement in Security of Database or Networks.
A proposal for „Protected Cloud‟ is being introduced here.
Next publication will be on the Protected Cloud Framework
by the same concerned Authors.
