This document discusses cloud computing and its key aspects. It begins by defining cloud computing as a collection of interconnected networks represented as a cloud in diagrams. The cloud allows users to access applications and store data remotely through an internet connection. There are three main types of cloud models - public, private, and hybrid clouds which combine public and private. The cloud provides major advantages like reduced costs, flexibility, and scalability. It discusses the various cloud service models including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). The document outlines the key characteristics of clouds such as elasticity, self-service provisioning, application programming interfaces, and billing/metering

Cloud computing is a network-based environment that focuses on sharing computations, Cloud computing networks access to a shared pool of configurable networks, servers, storage, service, applications & other important Computing resources. In modern era of Information Technology, the accesses to all information about the important activities of the related fields. In this paper discuss the advantages, disadvantages, characteristics, challenge, deployment model, cloud service model, cloud service provider & various applications areas of cloud computing such as small & large scale (manufacturing, automation, television, broadcast, constructions industries), Geographical Information system (GIS), Military intelligence fusion (MIS), business management, banking, Education, healthcare, Agriculture sector, E-Governance, project planning, cloud computing in family etc.
Swiftly increasing demand of computational
calculations in the process of business, transferring of files
under certain protocols and data centers force to develop an
emerging technology cater to the services for computational
need, highly manageable and secure storage. To fulfill these
technological desires cloud computing is the best answer by
introducing various sorts of service platforms in high
computational environment. Cloud computing is the most
recent paradigm promising to turn around the vision of
“computing utilities” into reality. The term “cloud
computing” is relatively new, there is no universal agreement
on this definition. In this paper, we go through with different
area of expertise of research and novelty in cloud computing
domain and its usefulness in the genre of management. Even
though the cloud computing provides many distinguished
features, it still has certain sorts of short comings amidst with
comparatively high cost for both private and public clouds. It
is the way of congregating amasses of information and
resources stored in personal computers and other gadgets
and further putting them on the public cloud for serving
users. Resource management in a cloud environment is a
hard problem, due to the scale of modern data centers, their
interdependencies along with the range of objectives of the
different actors in a cloud ecosystem. Cloud computing is
turning to be one of the most explosively expanding
technologies in the computing industry in this era. It
authorizes the users to transfer their data and computation to
remote location with minimal impact on system performance.
With the evolution of virtualization technology, cloud
computing has been emerged to be distributed systematically
or strategically on full basis. The idea of cloud computing has
not only restored the field of distributed systems but also
fundamentally changed how business utilizes computing
today. Resource management in cloud computing is in fact a
typical problem which is due to the scale of modern data

In this paper we are study-ing about cloud computing, their types, need to use cloud computing. We also study the architecture of the mobile cloud computing. So we included new techniques for backup and restoring data from mobile to cloud. Here we proposed to apply some compres-sion technique while backup and restore data from Smartphone to cloud and cloud to the Smartphone.
Cloud computing is on-demand access, via the internet, to computing resources—applications, servers (physical servers and virtual servers), data storage, development tools, networking capabilities, and more—hosted at a remote data center managed by a cloud services provider (or CSP). The CSP makes these resources available for a monthly subscription fee or bills them according to usage.

Design & Development of a Trustworthy and Secure Billing System for Cloud Com...iosrjce
Cloud computing is an important transition that makes change in service oriented computing
technology. Cloud service provider follows pay-as-you-go pricing approach which means consumer uses as
many resources as he need and billed by the provider based on the resource consumed. CSP give a quality of
service in the form of a service level agreement. For transparent billing, each billing transaction should be
protected against forgery and false modifications. Although CSPs provide service billing records, they cannot
provide trustworthiness. It is due to user or CSP can modify the billing records. In this case even a third party
cannot confirm that the user’s record is correct or CSPs record is correct. To overcome these limitations we
introduced a secure billing system called THEMIS. For secure billing system THEMIS introduces a concept of
cloud notary authority (CNA). CNA generates mutually verifiable binding information that can be used to
resolve future disputes between user and CSP. This project will produce the secure billing through monitoring
the service level agreement (SLA) by using the SMon module. CNA can get a service logs from SMon and stored
it in a local repository for further reference. Even administrator of a cloud system cannot modify or falsify the
data.
Cloud computing provide us a means by which we can access the applications as utilities, over the Internet. It allows us to create, configure, and customize applications online.
With cloud computing users can access database resources via the internet from anywhere for as long as they need without worrying about any maintenance or management of actual resources.

Abstract
What is the Intemet? It is collection of "interconnected networks" represented as a Cloud in network
diagrams and Cloud Compufing is a metaphor for certain parts of the Intemet. The IT enterprises and
individuals are searching for a way to reduce the cost of computation, storage and communication. Cloud
Computing is an lntemet-based technology providing "On-Demand" solutions for addressing these
scenarios that should be flexible enough for adaptation and responsive to requirements. The huge amount
of information that resides in the Cloud for servicing various enterprises and for making enterprises
secure sensitive data should reside in corporate data centers whereas the rest can reside in public data
centers. The Cloud manages upgrades anc provides information backup in the event of a disaster and/or a
system crash. The capital and operational costs of running data centers are reduced by Cloud Computing
making IT enterprises focus on strategic projects. In this paper. Cloud Computing is discussed and the
various aspects of Cloud Computing outlined such as advantages, limitations, problems and solutions,
applications with E-governance, emerging and future trends.
Keywords: Cloud Computing, E-govemance, future trends, on-demand
Introduction
The next stage in tbe evolution of the Intemet
is Cloud Computing but definitely not synonyms
with the Intemet. A Cloud within Cloud
Computing offers a way via which anything from
computing taxes to computing inlïastructure,
business applications processes to personal Joint
working which is delivered wherever and
whenever client needs [1]. Cloud Compufing
allows the client to access applications residing at
location other than client's computer or other
Intemet connected devices.
The essence of Cloud Computing is that the
service provider hosts the application that means
they will manage software updates, handle costs of
servers or development depending on how much
the client pays.
Defining the Cloud
A set of hardware, networks, storage,
services, and interfaces whieh enable the on time
delivery of demanded services is a Cloud [1,2].
Over the Intemet delivery of software, storage.
security [3] is done by the Cloud services as per
user demand.
The participants participating in the Cloud's
world are:
• End user who doesn't have any or very
little knowledge about the technology in use. The
end user can be customer or client. For small
businesses, the data center is the Cloud provider
and for larger organizations the IT enterprises
manage the inner procedure of the intemal and
external Cloud resources.
• Business management has - a duty for
data or services govemance in the Cloud.
• Cloud service provider has a duty to
maintain the IT assets.
Evolution of Cloud Computing, is on' the way
and completely able to change the way IT
enterprises use technology to provide service to
customers, clients. IT enterprises feel that the
Cloud model provides an efficient, cost effective
IT service delivery.

http://wjst.wu.ac.th
Cloud Computing is broken down into 3
different categories:
1. Public Cloud
2. Private Cloud
3. Hybrid Cloud (combine both public and
private Clouds).
The Public Cloud (extemal Cloud)
computing resources are on-demand purveyed over
the Intemet via Web applications or Web browsers
from an off-site third-party service provider.
The Private Cloud (intemal Cloud) is Cloud
Computing over private networks made
exclusively for one elient giving full control of
data, security and service quality and they can be
built and managed by a company's own
organization or by a Cloud service provider.
The Hybrid Cloud Computing blends
various public and private Clouds and introduces
complexity of distribution of application across
both a public and private Cloud.
Cloud's service model
The Cloud services are categorized into 3
models.[4]. For example, the SaaS service provider
might decide to offer separate platform services to
clients. The purpose of grouping these services
into 3 models is to aid in understanding the service
beneath the Cloud. All these service delivery
models require management and administration
(including security) [5].
Realizing infrastructure as a service
Infrastrueture as a Serviee (IaaS) is the
hardware delivery (such as servers, networking
technology, storage, and data center space) as a
service by Cloud Computing e.g. operating
systems and virtualization technology manages the
resources and then installing of resources in their
own data center which are paid services as per
usage. For example, Amazon's Elastic Compute
Cloud (Amazon EC2) provides a web interface
whieh allows clients to access virtual devices,
resources under paid user control. Amazon's EC2
is significant.
Searching platform as a service
In Platform as a Service (PaaS), the provider
delivers more than infrastrueture. It delivers an
integrated set of software that delivers everything a
developer might need to build an application and
can be viewed as an evolution of Web hosting. The
PaaS provides a standard platform for operating
system based provisioning, database, related
services, query proeessing. In PaaS, backup
services are kept on high node for disaster
recovery management. That means to develop the
software a elient needs, developers must focus on
designing the application instead of server's
compatibility, storage, and networking. These
entire infrastructures wiU be provided by PaaS.
Considering software as a service
The Software as a Service (SaaS) - provider
hosts business applications and delivered them as a
serviee. The cost of the software is as per-user
basis. The business gets the immediate beneflt of
reducing capital expenditures. The business gains
the flexibility to test new software on a rental basis
and then can continue to use and adopt the
software, if it proves suitable.
Cloud components [5]
Cloud Computing is derived from several
elements for providing solutions. These are:
Clients
• These are computers, mobile phones, and
laptops etc. that manage the information of end
users on the Cloud. The client can be a thin or
thick elient. Thin clients are devices (computers)
that do not have intemal devices whereas thick
clients are devices such as regular computers that
use Web browsers for getting connected with the
Cloud.
Data centers
• These are a collection of servers; it eould
be large room of your building full of servers on
the other side of world that get accessed via
Intemet.
Distributed servers
• The servers providing services are
geographically apart, but for the client devices
servers would appear to be working from the same
location.
Infrastructure
• The infrastructure relies on the
application and how the serviee provider choses to
build the solution over the Cloud.
Applications
• The components that the end user wants
to run/deploy. The major beneflt of Cloud
Computing is that client need not install, maintain
or support the application. The Cloud does it.
108 Walailak J Sei & Tech 2012; 9(2)
3. A Revolution in Information Technology - Cloud Connputing Divya BHATT
http://wjst.wu.ae.th
Platform
• The name is derived from PaaS (Platform
as a service) where the Cloud platform allows
users (business clients, developers, clients) to
deploy their applications over the Cloud platform
e.g.: Force.com, Salesforce.com's proprietary PaaS
service, the Google App Engine which runs off
Python and the Web hosting service Mosso.
Storage
• The physical storage is expensive and IT
enterprises spend billions in storage. The Cloud
services have given storage "wings". The Cloud is
expanding, hence accumulating more information
in it and .companies can concentrate on business
strategies.
Processing power
• The Cloud companies are ready to expand
their infrastructure, so when the customer is in
need of more processing power, that should be
available. The companies need not to worry about
infrastructure (purchasing/costs) and also need not
be concemed about power; if it is being used or if
the server has gone down.
Cloud characteristics
The Cloud embodies the following basic
characteristics [1,4,6]:
Elasticity and scalability
It is hard to anticipate how a customer will
use a service. It depends on whether the customer
will use it 3 times a year or use the application all
the time. However, services should be available all
the time 24*7, and be designed to provide high
scale service during peak times and also during
lighter zones. It should be scalable when additional
users are added or when requirements change and
ability to scale is achieved by providing elasticity.
Self-service provisioning
It is easy for customers to avail themselves of
Cloud services; the customer simply has to request
the type of service he requires. The request can be
computing, storage, software process or some
other resources from the service provider.
Application Programming Interfaces
(APIs)
Standardized APIs are needed for Cloud
services. The instruction regarding communication
between 2 applications or data sources is provided
by these interfaces. An easily link for the customer
with a Cloud service is done by a standardized
interface such that customized programming is not
needed, for example a customer relationship
management system with a financial management
system.
Billing and metering of services
A built-in service is needed to bill customers
in the Cloud environment and usage has to be
metered (tracked), to calculate that bill. The free
Cloud services Google's Gmail or Zoho's Internet-
based office applications are tracked.
Performance monitoring and measuring
A service management environment must be
included by the Cloud service provider which is an
integrated approach for managing physical
environinents and IT systems and must be able to
maintain the needed service level for organization
that is, service management has to be monitored to
optimize the services. It has to focus on key issues
that are the performance of the system, including
security and performance.
Many customers use their own monitoring
tools for determining whether the service level
requirements are being met.
Security
Many customers need to trust that the Cloud
services are safe. To give critical data or
application infrastructure to a Cloud-based service
provider requires an assurance that the information
has not been accidentally retrieved by another
company (or hacked). The security concept should
be dealt with as a serious issue in Cloud
Computing as critical data resides over Cloud. The
user trust can be built up if strategies regarding
network behavior, user behavior, processing
behavior are made [7].
Advantages of Cloud Computing
Cloud Computing has a number of
advantages from a user's point of view:
1. Lower cost: Being an online service.
Cloud Computing provides access to applications
using a browser while applications are stored on
distributed servers. It is lower cost for the user and
owners.
2. Free access: Access of applications from
any location makes users independent.
3. More storage area: As Cloud Computing
is distributed process, it maintains a storage den. It
provides more storage than personal storage.
4. Flexibility: Cloud Computing provides a
tension-free environment by upgrading, managing.
Walailak J Sei & Teeh 2012; 9(2) 109
4. A Revolution in Information Technology - Cloud Computing Divya BHATT
http://wjst.wu.ae.th
installing software on its own. It provides a
download free zone.
5. Mobility: The user can connect to the
Cloud from any location.
6. Ease of sharing: This is key component of
Cloud Computing. The information, resources and
hardware sharing for instant delivery.
7. Data safety: The files/data are safe unless
the hard drive get stolen.
8. Availability: There are several copies
which can he owned as per user demand.
9. Copyright convenience: Responsihility
for all aspects of licensing, maintenance and
authorization.
10. Synchronization: Different experts from
different issues, projects and locations.
II.Rapid elasticity: migrating from one
platform to another.
12.Location independent resources.
13.On-demand self-sufficient service and
ubiquitous network access
Limitations with Clouds
It is not possihle that Cloud Computing is
error-free and it may not he the best solution ever
needed in computing trends. The limitations of
Cloud Computing should he known, so that, they
can he removed [3].
1. Security: Major decisions in IT fields are
taken on the hasis of security risk. Hence, Cloud
Computing should he dynamic in providing
privacy, data integrity, management and other
issues. The Intranet, Extranet, Intemet and DMZ
boundaries are getting blurred and need security
challenges like authentication. Cloud vendor
reliability etc.
2. Unstructured programming: In Cloud
Computing, each Cloud has its own programming
support, data storage interfaces and programming
syntax. The standardization of methods and
interfaces are needed.
3. Consistency insurance: The data and
code, hoth are replicated over the Cloud and it is
very crucial to maintain consistency in data. Most
Cloud vendors provide data stores that do not
support relational models. Hence, can lead to
unneeded joins, had code and other prohiems for
developers.
Major problems with Cloud Computing
• There is risk of hacking in Cloud
Computing. The risk is not only for stored data hut
also for mishandling of transmitting data over the
Clouds.
• Sharing of documents Could he affected
hy masquerading i.e. your shared data can he
accessed hy anyone else.
• Cheap energy needed for data storage
centers as each center requires a large amount of
energy.
• The real henefit of Cloud dissipates into
the ether if geographical and political horders
fracture the Cloud into groupings.
Emerging trends in Cloud Computing [6,9]
• Enterprises are huilding their own Clouds
e.g. IBM "Blue Cloud", Microsoft '"Azure",
Google "GooG", Salesforce "Successforce". The
data centers in the private Clouds are managed hy
third parties (Amazon.com) and hy IT staff In a
virtual environment these private Clouds are
managed centrally.
• Cloud Computing diverts the important
points of IT enterprises hy taking the burden of
technological implementation into its Cloiid. This
helps enterprises to concentrate on their husiness
process, developing new technologies. This will
improve the quality of projects and will save a lot
of time.
• The security procedures that physically
safeguard data are developing. The thinking of
keeping data in one place is not favorable for
growing enterprises.
• Cloud Computing is not limited to
providing software and hardware help hut also
consultancy, on-demand services such as
Salesforce's Successforce which helps clients to
get Salesforce consultancy or connect them to their
partners Accenture, Deloitte, the online tax
preparation service which is provided hy Tango of
HandR Block, and NetSuite which provides on-
demand service to clients hy collaborating with
NetSuite partners.
• The personal computer has become
slimmer with fewer or no applications. The only
thing needed will he a Weh-hrowser in it for
connecting to heavy-lifting Cloud services.
• With huge databases, the Cloud will
become a knowledge pool.
110 Walailak J Sei & Teeh 2012; 9(2)
5. A Revolution in Information Technology - Cloud Computing Divya BHATT
http://wjst.wu.ac.th
• In future, human intelligence will be
incorporated into the Cloud and new horizons will
open for Artificial Intelligence making Cloud the
"IT THING".
• Green Technology is emerging with the
help of Cloud Computing as fewer natural
resources will be utilized.
• Cloud economics involves paying only
for what you use. Cloud economics 101: matches
elastic applications to Cloud platforms and moving
transient apps in and out so their costs are
constantly retuming to zero. Cloud economics 201:
designs and optimizes applications to take
advantage. Cloud economics 301 : knows when and
which Cloud to be used for optimum profitability.
Earlier efforts of Amazon Web Service's Spot
Instances and Enomaly's SpotCloud for showing
the way and the Cloud Price Calculator for
normalize costs.
• Autodesk's Project Cumulus and the ISVs
queuing up behind GreenButton are showing the
way as both these companies know how to put a
Cloud behind applications and in so doing deliver
game-changing productivity. Such moves leverage
Cloud economics and may disrupt
superComputing.
• Cloud Computing not only will help
enterprises gain insight from information. It will
help to derive revenue from it too. Services like:
Windows Azure DataMarket will help enterprises
leverage data sources more easily and become one
of those providers themselves. The Associated
Press, Dun & Bradstreet and ESRI are appropriate
models.
• Cloud security will be proven not only by
the providers alone, as it is shared effort, hence,
security will be addressed by both client and
provider.
• The Berlin-based company Zimory's
open-technology can get connected with large
number of Clouds and thousands of machines can
be scaled-up [9].
• In the field of Cloud Computing, Abiquo
[9] with promising startup boasts including hyper-
peak support portfolio with leading vendors such
as Microsoft, Citrix, VMware and Zend, the firm
bids a permission-based hierarchy that enables
enterprises to forge public, private or hybrid
Clouds sweeping data centers on- and off-
premises. It provides a support system to remove
the vendor lock-in problem.
• The recent entrant in the market of Cloud
NephoScale [9] is a public Cloud infrastructure
platform offering pay-by-the-hour servers, object-
based storage, and dedicated on-demand servers.
E-governance and Cloud Computing [10,11]
The technology using the Intemet, remote
servers for maintaining applications and data is
Cloud Computing. It allows the process of
business applications from remote places. It helps
in storing personal files, accessing them and
managing them e.g. Yahoo mail, Gmail. Only an
Internet connection is needed. Companies and the
Indian Govemment are most affected by Cloud
Computing. Hence, Cloud technology can be
utilized for providing doorstep services for the
common man with the help of E-govemance. E~
govemance applications include Indian Railway,
Indian Bank services and ATMs. The E-
govemance deals with citizens/public in two ways:
Intemet economy and Interaction. The Intemet
economy deals with taxes, addition of revenues,
space utilization and interaction deals with G2G,
G2B B2B etc.
• SaaS can be used for E-governance (G2B,
G2G, G2E, G2C) and provide applications such as
Job-Portal, Service-help desk. Municipal
management systems, E-court, E-police, District
management systems.
• PaaS database, backup services can be
provided efficiently and provide dynamic OS,
query service, workflow service for providing
database services, backup services, and efficient
management for disaster recovery.
• laaS can allow various clients to utilize
storage, hardware utility and the network. The
application designers can focus on features and
utility of application instead of worrying about'
scalability.
Cloud Computing dimensions for E-
govemance include:
1. Vertical Dimension: healthcare, land
records, passport database and other services
provided by the govemment to the citizen of the
country.
2. Horizontal Dimension: public access and
participation, policy publications, public grievance
and procedures.
E-govemance challenges can be overcome
with Cloud Computing as it allows for sharing of
large resources and making strategies. Cloud

Computing can help in monitoring or analyzing
large amounts of data detection and fraud. By
keeping services of the provider accountable we
can control corruption. The proeesses of E-
governance such as application migration of any
citizen, recovering lost data, taking back ups,
minimizing pollution etc. can be improved.
Moreover, with the help of Cloud Computing lots
of resources can be saved such as air-conditioners
power, electricity, paper resources that make it
Green Technology.
- Some of the E-governanee challenges and
benefits of Cloud Computing [12]:
1. Scaling of data: to manage the large
amount of data of E-governance, databases should
be scalable. The Cloud databases should be
considered as On-high demand, high-end
scalability.
2. Audit and log: it deals with content
traceability. With this service, corruption in
government can be controlled, as a process audit
and security audit can be done periodically. Clouds
can help in analyzing huge amount of data and
fraud detection.
• 3. New instances, duplication and migration:
the architecture of Cloud Computing provides
excellent features for creation of an instance of any
application that reduees the deploy time of a new
application.
4. Disaster recovery: avoid data loss and
make services available "round the clock". Cloud
virtualization technology provides backup and
restoring facilities besides this it offers seamless
migration from one platform to another as
compared to other data centers.
5. Better govemance: for better govemance
data center usage, peak loads, consumption levels,
power usage along with time are major factors
needed to be monitored for good resource
utilization. Cloud offers Business Intelligence
infrastructure that seamlessly integrates with
different frameworks like MAPREDUCE (Apache
Hadcoop).
6. Policy management: dealing with
different citizens, understanding their needs along
with infrastructure and data center, policies need to
be imposed in day to day processes. Cloud
Computing helps in policy implementation in data
center with respect to security, application
deployment etc.
7. New migration: eo-existing with new
versions or co-locating with them.
8. System integration: Cloud architecture is
built on the SOA feature that provides an on-
demand user service.
Conclusions and future scope
Cloud Computing provides attractive
capabilities, environments, and operating systems
solutions. This paper discusses the concept of
Cloud Computing in detail and provides
information of trends, areas to be answered,
categories of Cloud, and models for Cloud
Computing (IaaS, PaaS, SaaS). Cloud Computing
needs to be applied fully for the benefit of every
citizen in day to day life. Cloud Computing is
beeoming a synonym for Green computing as it
reduces paper work and power consumption.
Cloud Computing has become a non-restrictive
platform for many applications. But there are many
issues that need to be addressed but this is still set
to revolutionize the way we use the Intemet.
This paper tries to conclude Cloud
Computing on the basis of its theory (broadly). In
the future, the practical view of Cloud Computing
will be studied and researched. The practical view
will have case studies of some leading companies
in this field such as Microsoft, Amazon to get
insight into the Cloud Computing world.
