Cloud computing is a rapidly emerging technology that has removed the saddle of buying licensed software and heavy hardware. By exploiting this technology, clients are able to access resources remotely by using a simple web browser. They are not required to maintain hardware devices or software applications, so it saves managing cost and time for organizations. Many industries, such as banking, healthcare, and education, are moving towards the cloud due to the efficiency of services provided by the pay-per-use pattern. The utilization and payment process of cloud computing is similar to other common utilities such as electricity. As the users of electricity are only required to pay for the amount of electricity consumed throughout the month. Similarly, cloud providers charge the users based on the exploitation of a cloud system or resources such as processing power used, transactions carried out, bandwidth consumed, data transferred, or storage space occupied. Cloud computing is a completely internet dependent technology where client data is stored in the data center of a cloud provider. There are various challenges for adopting cloud computing such as privacy, interoperability and reliability. Beside these challenges, there are also several benefits for adopting this technology such as cost savings, easy scalability, and increased productivity. This research paper introduces a big picture of cloud computing and analyzes the key challenges as well as benefits of adopting the paradigm of cloud computing.

Abstract—Cloud computing has elevated IT to newer limits
by offering the market environment data storage and capacity
with flexible scalable computing processing power to match
elastic demand and supply, whilst reducing capital expenditure.
However the opportunity cost of the successful implementation of
Cloud computing is to effectively manage the security in the
cloud applications. Security consciousness and concerns arise as
soon as one begins to run applications beyond the designated
firewall and move closer towards the public domain. The purpose
of the paper is to provide an overall security perspective of Cloud
computing with the aim to highlight the security concerns that
should be properly addressed and managed to realize the full
potential of Cloud computing. Gartner’s list on cloud security
issues, as well the findings from the International Data
Corporation enterprise panel survey based on cloud threats, will
be discussed in this paper.

I. INTRODUCTION
The success of modern day technologies highly depends on
its effectiveness of the world’s norms, its ease of use by end
users and most importantly its degree of information security
and control. Cloud computing is a new and emerging
information technology that changes the way IT architectural
solutions are put forward by means of moving towards the
theme of virtualisation: of data storage, of local networks
(infrastructure) as well as software [1-2].
In a survey undertaken by the International Data
Corporation (IDC) group between 2008 and 2009, the majority
of results point to employing Cloud computing as a low-cost
viable option to users [3]. The results also show that Cloud
computing is best suited for individuals who are seeking a
quick solution for startups, such as developers or research
projects and even e-commerce entrepreneurs. Using Cloud
computing can help in keeping one’s IT budget to a bare
minimum. It is also ideally suited for development and testing
scenarios. It is the easiest solution to test potential proof of
concepts without investing too much capital. Cloud computing
can deliver a vast array of IT capabilities in real time using
many different types of resources such as hardware, software,
virtual storage once logged onto a cloud. Cloud computing can
also be part of a broader business solution whereby prioritised
applications utilise Cloud computing functionality whilst other
critical applications maintain organisational resources as per
normal. This allows for cost saving whilst maintaining a secure
degree of control within an orgainsation.
Cloud computing can be seen as a service-oriented ...
A Secure Cloud Storage System with Data Forwarding using Proxy Re-encryption ...IJTET Journal
1. The document describes a secure cloud storage system that uses proxy re-encryption to allow authorized data sharing among multiple users. It focuses on privacy issues in cloud storage and proposes a solution using proxy re-encryption.
2. Proxy re-encryption schemes allow a proxy (like a cloud server) to alter an encrypted file so that it can be decrypted by another user, without revealing the content to the proxy. The proposed system uses this to share files encrypted for one user so they can be decrypted by another authorized user.
3. The system assigns different trust levels to control what data different users can access. A high trust level allows access to more data fields, while a low trust level restricts access. This trust
A Secure Cloud Storage System with Data Forwarding using Proxy Re-encryption ...IJTET Journal
Cloud computing provides the facility to access shared resources and common support which contributes services on
demand over the network to perform operations that meet changing business needs. A cloud storage system, consisting of a collection
of storage servers, affords long-term storage services over the internet. Storing the data in a third party cloud system cause serious
concern over data confidentiality, without considering the local infrastructure limitations, the cloud services allow the user to enjoy the
cloud applications. As the different users may be working in the collaborative relationship, the data sharing becomes significant to
achieve productive benefit during the data accessing. The existing security system only focuses on the authentication; it shows that
user’s private data cannot be accessed by the fake users. To address the above cloud storage privacy issue shared authority based
privacy-preserving authentication protocol is used. In the SAPA, the shared access authority is achieved by anonymous access request
and privacy consideration, attribute based access control allows the user to access their own data fields. To provide the data sharing
among the multiple users proxy re-encryption scheme is applied by the cloud server. The privacy-preserving data access authority
sharing is attractive for multi-user collaborative cloud applications.

Abstract—Cloud computing has elevated IT to newer limits
by offering the market environment data storage and capacity
with flexible scalable computing processing power to match
elastic demand and supply, whilst reducing capital expenditure.
However the opportunity cost of the successful implementation of
Cloud computing is to effectively manage the security in the
cloud applications. Security consciousness and concerns arise as
soon as one begins to run applications beyond the designated
firewall and move closer towards the public domain. The purpose
of the paper is to provide an overall security perspective of Cloud
computing with the aim to highlight the security concerns that
should be properly addressed and managed to realize the full
potential of Cloud computing. Gartner’s list on cloud security
issues, as well the findings from the International Data
Corporation enterprise panel survey based on cloud threats, will
be discussed in this paper.

I. INTRODUCTION
The success of modern day technologies highly depends on
its effectiveness of the world’s norms, its ease of use by end
users and most importantly its degree of information security
and control. Cloud computing is a new and emerging
information technology that changes the way IT architectural
solutions are put forward by means of moving towards the
theme of virtualisation: of data storage, of local networks
(infrastructure) as well as software [1-2].
In a survey undertaken by the International Data
Corporation (IDC) group between 2008 and 2009, the majority
of results point to employing Cloud computing as a low-cost
viable option to users [3]. The results also show that Cloud
computing is best suited for individuals who are seeking a
quick solution for startups, such as developers or research
projects and even e-commerce entrepreneurs. Using Cloud
computing can help in keeping one’s IT budget to a bare
minimum. It is also ideally suited for development and testing
scenarios. It is the easiest solution to test potential proof of
concepts without investing too much capital. Cloud computing
can deliver a vast array of IT capabilities in real time using
many different types of resources such as hardware, software,
virtual storage once logged onto a cloud. Cloud computing can
also be part of a broader business solution whereby prioritised
applications utilise Cloud computing functionality whilst other
critical applications maintain organisational resources as per
normal. This allows for cost saving whilst maintaining a secure
degree of control within an orgainsation.
Cloud computing can be seen as a service-oriented ...
A Secure Cloud Storage System with Data Forwarding using Proxy Re-encryption ...IJTET Journal
1. The document describes a secure cloud storage system that uses proxy re-encryption to allow authorized data sharing among multiple users. It focuses on privacy issues in cloud storage and proposes a solution using proxy re-encryption.
2. Proxy re-encryption schemes allow a proxy (like a cloud server) to alter an encrypted file so that it can be decrypted by another user, without revealing the content to the proxy. The proposed system uses this to share files encrypted for one user so they can be decrypted by another authorized user.
3. The system assigns different trust levels to control what data different users can access. A high trust level allows access to more data fields, while a low trust level restricts access. This trust
A Secure Cloud Storage System with Data Forwarding using Proxy Re-encryption ...IJTET Journal
Cloud computing provides the facility to access shared resources and common support which contributes services on
demand over the network to perform operations that meet changing business needs. A cloud storage system, consisting of a collection
of storage servers, affords long-term storage services over the internet. Storing the data in a third party cloud system cause serious
concern over data confidentiality, without considering the local infrastructure limitations, the cloud services allow the user to enjoy the
cloud applications. As the different users may be working in the collaborative relationship, the data sharing becomes significant to
achieve productive benefit during the data accessing. The existing security system only focuses on the authentication; it shows that
user’s private data cannot be accessed by the fake users. To address the above cloud storage privacy issue shared authority based
privacy-preserving authentication protocol is used. In the SAPA, the shared access authority is achieved by anonymous access request
and privacy consideration, attribute based access control allows the user to access their own data fields. To provide the data sharing
among the multiple users proxy re-encryption scheme is applied by the cloud server. The privacy-preserving data access authority
sharing is attractive for multi-user collaborative cloud applications.

Methodologies for Enhancing Data Integrity and Security in Distributed Cloud ...IIJSRJournal
Usually, cloud infrastructure is used individually by businesses, whereas the hybrid cloud would be a blend of two or many kinds of clouds. Because as clouds become increasingly common, safety issues also expanding. Because of such cybersecurity threats, numerous experts suggested procedures as well as ways to assure internet confidentiality. Providers of cloud-based services were accountable for the complete safety of cloud information. Nevertheless, since the clouds are accessible (easily accessible over the World wide web), much research has been conducted on cloud storage cybersecurity. This paper describes methods for enhancing security and reliability in decentralized cloud-based solutions, as well as suggests a few security solution methods of implementation.

Data Security Model Enhancement In Cloud EnvironmentIOSR Journals
This document discusses enhancing data security in cloud environments. It begins by providing background on cloud computing, including its key characteristics and architecture. The document then discusses existing security concerns with cloud computing, as sensitive user data is stored remotely by cloud providers. The main objective is to propose an enhanced data security model for clouds. The proposed model uses a three-layer architecture and efficient algorithms to ensure security at each layer and solve common cloud data security issues like authentication, data protection, and fast data recovery.
A traditional computing environment requires a costly
infrastructure to offer a better service to users. The introduction
of cloud computing has changed the working environment from
traditional to virtual. A larger number of IT companies are
utilizing the cloud. On the one hand, the cloud attracts more
number of consumers by offering services with minimized
capital cost and virtual infrastructure. On the other hand, there
are a risk and security challenges in cloud computing that
makes the user not to move completely towards it. The cloud
environment is more vulnerable to security breaches and data
theft. Moreover, insider attacks are more frequent in larger
enterprises. An unauthenticated user can cause more damage
to company reputation. The cloud service providers are trying
to provide a secure work environment for users. However,
there is a lack of global standards and policies to invoke
security measures in cloud computing. This study aims to
highlight and classify security challenges and trust issues in the
cloud environment.
The survey was conducted in various institutions and
governmental organizations in Saudi Arabia to study the
opinions of stakeholders on cloud computing security
challenges and risks.

Security of Data in Cloud Environment Using DPaaSIJMER
The rapid development of cloud computing is giving way to more cloud services, due to
which security of services of cloud especially data confidentiality protection, becomes more critical.
Cloud computing is an emerging computing style which provides dynamic services, scalable and payper-use.
Although cloud computing provides numerous advantages, a key challenge is how to ensure
and build confidence that the cloud can handle user data securely. This paper highlights some major
security issues that exist in current cloud computing environments. The status of the development of
cloud computing security, the data privacy analysis, security audit, information check and another
challenges that the cloud computing security faces have been explored. The recent researches on data
protection regarding security and privacy issues in cloud computing have partially addressed some
issues. The best option is to build data-protection solutions at the platform layer. The growing appeal
of data protection as a service is that it enables to access just the resources you need at minimal
upfront expense while providing the benefits of enterprise-class data protection capabilities. The
paper proposes a solution to make existing developed applications for simple cloud Systems
compatible with DPaaS. The various security challenges have been highlighted and the various
necessary metrics required for designing DPaaS have been investigated.

Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

of services to clients, i.e., Software as a Service (SaaS),

Abstract— Cloud computing is a rapidly emerging technology
that has removed the saddle of buying licensed software and
heavy hardware. By exploiting this technology, clients are able to
access resources remotely by using a simple web browser. They
are not required to maintain hardware devices or software
applications, so it saves managing cost and time for
organizations. Many industries, such as banking, healthcare, and
education, are moving towards the cloud due to the efficiency of
services provided by the pay-per-use pattern. The utilization and
payment process of cloud computing is similar to other common
utilities such as electricity. As the users of electricity are only
required to pay for the amount of electricity consumed
throughout the month. Similarly, cloud providers charge the
users based on the exploitation of a cloud system or resources
such as processing power used, transactions carried out,
bandwidth consumed, data transferred, or storage space
occupied. Cloud computing is a completely internet dependent
technology where client data is stored in the data center of a
cloud provider. There are various challenges for adopting cloud
computing such as privacy, interoperability and reliability.
Beside these challenges, there are also several benefits for
adopting this technology such as cost savings, easy scalability,
and increased productivity. This research paper introduces a big
picture of cloud computing and analyzes the key challenges as
well as benefits of adopting the paradigm of cloud computing.

I. INTRODUCTION
There are various reasons for business organizations to
move towards IT solutions that include cloud computing. First
of all, organizations are only required to pay when they use
certain resources. Secondly, organizations are not required to
pay maintenance costs for managing various resources across
the enterprise. Finally, cloud computing models provide
business agility. Since the entire IT infrastructure can scale up
or down to meet desired demands, organizations can easily
meet the needs of rapidly changing markets to ensure that they
are always on the leading edge for their consumers. Cloud
computing is the advanced picture of various technologies
such as grid computing, distributed computing and Serviceoriented Architecture (SOA) [1]. Cloud computing involves
three types of stakeholders i.e. providers, adopters and users.
Providers are the IT industries that provide the facility of
cloud services to the adopters, i.e. business organizations. The

By using SaaS, clients don’t need to install and buy
licensed applications. They just need to follow the pay-per-use
pattern. However, SaaS is not fully reliable when it comes to
the use of real-time applications such as 3D games [1]. These
applications require buffering time, so their performance
becomes slower when users access them through the internet.
PaaS is the delivery of a computing platform over the web as a
service. PaaS enables clients to create web applications rapidly
without the cost and complexity of buying and managing the
underlying software or hardware.

DEPLOYMENT MODELS
The cloud providers offer different types of clouds (cloud
deployment models) to an organization according to their
business requirements. Normally there are four different types
of cloud deployment models, i.e. public, private, hybrid and
community cloud.
B. Private Clouds
Private clouds are cloud services provided within the
enterprise as shown in Fig.3 [4]. These clouds exist within the
company firewall and are managed by the enterprise.

ES
A. Public Clouds
Public clouds are cloud services provided by a third party
vendor. These clouds exist beyond the company firewall as
shown in Fig.2 [4]. These clouds are fully hosted and managed
by the cloud provider.
takes on the responsibilities of installation, management,
provisioning, and maintenance. Customers are only charged
for the resources they use, so under-utilization is eliminated.
These services are usually offered with convention over
configuration, meaning that they are delivered with the idea of
accommodating the most common use cases. Configuration
options are usually a smaller subset than what they would be if
the resource was controlled directly by the consumer. Since
consumers have little control over the infrastructure, processes
requiring powerful security and regulatory compliance are not
always a good fit for public clouds [3].
T
IaaS is the delivery of huge computing resources such as
the capacity of processing, storage, and networks. It enables
clients to use virtual software, hardware, datacenters and
networking components as on-demand services. The clients are
not required to purchase personal hard disks or other storage
devices [1]. It seems to be that cloud computing is on its
approach to remove the need for hardware devices and licensed
applications. In the near future clients will be able to use
software such as word processing applications and operating
systems without the need for heavy hardware devices, as the
client system is not required to process these applications [2].

Figure 3. Private cloud model
Private clouds offer several similar benefits to those of
public clouds but with one major difference that the enterprise
is in charge of setting up and maintaining the cloud. The
difficulty and cost of establishing an internal cloud can be
very expensive, and the cost of continual operation of the
cloud might exceed the cost of using a public cloud. Private
clouds offer some advantages compared to public clouds such

as control over managing the cloud. Organizations feel in
control over their cloud services and security [3].
D. Community Clouds
The community cloud is a new and rarely offered cloud
model. These clouds are based on a group of several
organizations that jointly construct and share the same cloud
infrastructure as well as policies, requirements, values, and
concerns. These community clouds are normally based on an
agreement between related business organizations such as
banking or educational organizations. The cloud infrastructure
can be hosted by a third-party vendor or one of the
organizations within the community [5].
III.
CHALLENGES FOR ADOPTING THE PARADIGM OF CLOUD
COMPUTING
The key challenges that create barriers between cloud
computing and its adopters are privacy, interoperability, and
reliability.
T
C. Hybrid Clouds
Hybrid clouds are a combination of public and private
clouds. These clouds would typically be created by the
enterprise, and management responsibilities would be split
between the enterprise and the cloud provider. The hybrid
cloud provides services that are in both the public and private
clouds as shown in Fig.4 [4]. Hybrid clouds are required when
a company needs to employ the services of both a public and
private cloud. In this case, a company can outline the goals
and needs of services, and obtain them from the public or
private cloud as appropriate. A well-constructed hybrid cloud
can be useful for providing secure services such as receiving
customer payments, as well as those that are secondary to the
business, such as employee payroll processing.
implementation even more complicated [3].
IJ
A
ES
A. Trust and Privacy
Nowadays cloud computing is completely moving towards
virtualization. In a virtualized cloud environment, the cloud
provider allocates a virtual machine (VM) for each client. The
VM runs the client’s applications and maintains virtual
storage. The VM runs on the underlying provider’s operating
system. The advantage of virtualization in cloud computing is
the isolation of VMs where the VM of each client is isolated
from other clients, so that if any client's VM is infected with a
virus or becomes malicious, it will not affect the other clients
under the same provider because they are residing on separate
VMs. But there is an issue related to the privacy of
information and trust. When security is managed by a cloud
provider, clients often don’t trust the level of security provided
if the information stored is very critical and confidential [6].
Normally organizations in the healthcare and banking sectors
are not satisfied enough with the security. Conversely, some
organizations are not satisfied enough to trust the provider.
They may feel that the provider may leak their confidential
information. Thus, even if a cloud provider creates powerful
security procedures to block hackers from accessing the cloud
environment, clients may be hesitant to adopt this technology
due to issues of privacy and trust of provider.
Figure 4. Hybrid cloud model
The major drawback to the hybrid cloud is the difficulty in
effectively creating and governing such a solution. Services
from different sources must be obtained and provisioned as if
they originated from a single location, and interactions
between private and public components can make the
ISSN: 2230-7818
B. Interoperability
This is the ability of two or more systems work together in
order to exchange information and use that exchanged
information. Many public cloud networks are configured as
closed systems and are not designed to interact with each
other. The lack of integration between these networks makes it
difficult for organizations to combine their IT systems in the
cloud and realize productivity gains and cost savings. To
overcome this challenge, industry standards must be
developed to help cloud service providers design interoperable
platforms and enable data portability. Organizations need to
automatically provision services, manage VM instances, and

IV.
B. Easy Scalability
Cloud computing is a flexible model and provides ondemand business scalability by using on-demand cloud
services such as SaaS, PaaS or IaaS. Scalability is another
aspect of cloud computing that can provide an advantage to
business. Depending on service needs at any given time
period, a company can scale back the amount of virtual server
space they need, or raise it according to their pattern of
growth. This is especially helpful for new businesses that are
trying to save money at every possible turn. A smaller
business does not have to pay a fixed rate for a certain amount
of data center hosting that they might not even use. In this
way, a company can scale up the level of space they need on a
dedicated server through cloud computing. A low-cost
dedicated server can easily save a business thirty to forty
percent of their average annual cost for IT [9]. If an
organization is a SaaS user, it can request to adopt PaaS or
IaaS whenever required. With an on-demand integration
solution, companies can quickly and easily increase or
decrease connections, transactions, or the number of
companies in their integration community, and then scale up
when business requires it.

The challenge of reliability comes into the picture when a
cloud provider delivers on-demand software as a service. The
software needs to have a reliability quality factor so that users
can access it under any network conditions (such as during
slow network connections). There are a few cases identified
due to the unreliability of on-demand software. One of the
examples is Apple's MobileMe cloud service, which stores
and synchronizes data across multiple devices. It began with
an embarrassing start when many users were not able to access
mail and synchronize data correctly. To avoid such problems,
providers are turning to technologies such as Google Gears,
Adobe AIR, and Curl, which allow cloud based applications to
run locally, some even allow them to run in the absence of a
network connection. These tools give web applications access
to the storage and processing capabilities of the desktop,
forming a bridge between the cloud and the user's own
computer [8]. Considering the use of software such as 3D
gaming applications and video conferencing systems,
reliability is still a challenge to achieve for an IT solution that
is based on cloud computing.
data storage and are ideal for disaster recovery and business
continuity, so business organizations are not worried about the
loss of data and creating recovery backups [9].
T
work with both cloud-based and enterprise-based applications
using a single tool set that can function across existing
programs and multiple cloud providers. In this case, there is a
need to have cloud interoperability. Efforts are under way to
solve this problem. For example, the Open Grid Forum, an
industry group, is working on the Open Cloud Computing
Interface, which would provide an API for managing different
cloud platforms. Until now it has remained a challenging task
in cloud computing [7].
BENEFITS FOR ADOPTING THE PARADIGM OF CLOUD
COMPUTING

A
Beside the challenges of cloud computing, there are
numerous benefits of cloud computing that encourages
business organizations to adopt IT solutions based on the
cloud. The key benefits of adopting cloud computing are cost
reduction, easy scalability and increased productivity.
A. Cost Reduction
The usage of SaaS enables business organizations to
minimize payment costs for IT resources and maximize
business performance as well as profit. Clients are required to
pay according to the use of resources. If clients need an
application for a short period of time, it is useless to buy the
application by paying the complete licensing cost. The
solution based on cloud computing cuts down the cost of
paying for the applications and resources that are not in use
any more. As the service provider owns and hosts the
software, the users can benefit from ongoing upgrades and
maintenance without the associated costs and time constraints.
With the use of cloud technology clients are not required to
create data backups. Cloud providers that use multiple
redundant sites can provide reliable and secure locations for

C. Increased Productivity
In this rapid era of technology and innovations, business is
growing rapidly. The demands of customers are increasing
with high speed and they need the products more quickly with
less time. In order to achieve these demands, business
organizations around the globe need to communicate and
collaborate by using IT resources such as collaborative
applications and remote access web services. Cloud
computing provides these business demanded application on
the cloud or internet. Users are able to access these
applications at anytime and anywhere. Business people can
arrange their meetings and share messages or emails by using
cloud applications provided by various vendors. Cloud
computing has moved mobility ahead in business, as well.
Business people can access the services of cloud just by using
a web browser on a Smartphone, tablet, or notebook. There is
no need to use laptops or desktop computers. With the help of
cloud applications, salespersons can view updated orders from
customers at anytime. The quick processing of customer
orders enables organizations to achieve customer satisfaction
levels that automatically lead to increased productivity and
profit.

CONCLUSION AND FUTURE WORK
By discussing the key challenges and benefits for adopting
cloud computing, it is clear enough that adoption of cloud is
still remained as a question mark for organizations. Due to
these challenges, organizations are avoiding cloud computing,
but because of the benefits, they are in favor of adopting cloud

computing. In order to abolish the challenges of cloud
computing, several software enterprises such as Microsoft,
IBM, Google, and Amazon are continuously contributing to
the field of cloud computing by developing innovative cloud
applications and platforms. Nowadays, some companies have
started to adopt cloud computing. According to a survey
conducted by International Data Corporation (IDC), 53% of
organizations in the Asia-Pacific region are already using
some form of cloud computing services, and the remaining
47% of the organizations have plans to adopt private or public
cloud services in the next 12 months [10]. The survey results
indicate that, at present, cloud computing is a not highly
adopted technology, but due to growing contributions by
researchers and IT industries, it seems that within a few short
years, global business will be on the cloud and there will not
be any need for using heavy hardware devices, desktop PCs,
or laptops. A Smartphone or tablet will be the most in-demand
device to run a business organization successfully. The future
direction of this research will focus on developing and
designing new techniques to eliminate cloud computing
challenges.
