Cloud computing is a computing technology aiming to share storage, computation, and services transparently
among a massive users. Current cloud computing systems pose serious limitation to protecting the confidentiality
of user data. Since the data share and stored is presented in unencrypted forms to remote machines owned and
operated by third party service providers despite it sensitivity (example contact address, mails), the risks of
disclosing user confidential data by service providers may be quite high and the risk of attacking cloud storage
by third party is also increasing. The purpose of this study is to review researches done on this technology,
identify the security risk and explore some techniques for protecting users‟ data from attackers in the cloud.

The document summarizes a study that used numerical modeling and laboratory experiments to evaluate the effectiveness of steam injection for remediating soils contaminated with light non-aqueous phase liquids (LNAPLs) like kerosene. The numerical modeling was done using MATLAB and governing equations were developed. The experimental aspect involved injecting dry steam into sand columns containing saturated mixtures of kerosene and sand. As steam increased temperature, kerosene viscosity decreased and it was recovered over time. Results showed that higher pressure, larger soil grain size, and longer treatment time increased kerosene flow rate and recovery efficiency, which was found to be 80-85% on average. Therefore, steam injection was found to be an effective thermal remediation

An Efficient MDC based Set Partitioned Embedded Block Image CodingDr. Amarjeet Singh
In this paper, fast, efficient, simple and widely used
Set Partitioned Embedded bloCK based coding is done on
Multiple Descriptions of transformed image. The maximum
potential of this type of coding can be exploited with discrete
wavelet transform (DWT) of images. Two correlated
descriptions are generated from a wavelet transformed image
to ensure meaningful transmission of the image over noise
prone wireless channels. These correlated descriptions are
encoded by set partitioning technique through SPECK coders
and transmitted over wireless channels. Quality of
reconstructed image at the decoder side depends upon the
number of descriptions received. More the number of
descriptions received at output side, more enhance the quality
of reconstructed image. However, if any of the multiple
description is lost, the receive can estimate it exploiting the
correlation between the descriptions. The simulations
performed on an image on MATLAB gives decent
performance and results even after half of the descriptions is
lost in transmission.
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
centers, the variety of resource types and their inter
dependencies, unpredictability of load along with the range of
objectives of the different actors in a cloud ecosystem.

ABSTRACT
Cloud Computing has recently evolved as compelling paradigm for delivering and managing resources as
service over the internet. IT industry is much more affected by this technology owing its ability to provide more
benefits and permits enterprises to start from the small and enhance resources only when there is a rise in service
demand. Although cloud computing is providing many facilities but there are many issues which is yet to be
addressed. In this paper, we present a survey of cloud computing, its key concepts, state-of-the-art
implementation and research issues as well. The objective of this paper is to provide better understanding of
cloud computing and identify important research directions in this burgeoning area of computer science.
Keywords – Cloud Architecture, Cloud Computing, Data Center, Hypervisor, Virtualization,
I. INTRODUCTION
In the last few years, owing unprecedented
success of internet has made computing resources
ubiquitously attainable. And this lead to emergence
of new concept called “Cloud Computing”.
Nowadays, researchers are also showing more
interest in this area because of its capability to
provide reliable, powerful and cost-efficient cloud
platform and can assists the one to gain more profits
from this paradigm. Owing its unlimited benefits,
Cloud Computing is now being more adopted by
every business organizations, colleges/institutes and
many IT fields.
Cloud Computing is not treated as single
entity. CC is made of two terms: Cloud – It is a
metaphor of “Internet” means utilization of internet
based technology and Computing – It means use of
computing technology. CC enables the user to access
the resources anytime from any platform such as
Smartphone, Mobile Computing Platform and the
desktop. Many companies are providing services
from the cloud. Some of the examples are Google,
Microsoft and Salesforce.com etc
In cloud computing, the traditionally role of
service provider is divided into two phases: the
infrastructure providers who manage cloud platforms
and lease resources as per usage-based pricing model,
and service providers who rent resources from one or
many infrastructure providers to serve the end users.
A Cloud Computing infrastructure is
basically consisting from three elements as follows:
Clients, Datacenter and Distributed Servers (See Fig.
1).
Figure 1: Elements of Cloud Computing
Clients – Clients are the terminal from which
user perform certain task. Examples are PDAs,
Smartphone and Desktops etc.
Datacenter – A datacenter is a multitude of
servers that host the applications needed by an
organization. Today trend is of virtualized
servers that are creation of multitude servers on
one scalable machine through a program called
hypervisor.
Distributed Server – In distributed servers, one
or more central servers store file which can be
accessed with proper authorization rights by
remote clients in the network.
II. OVERVIEW OF CLOUD COMPUTING
2.1 Definition
The Cloud Computing is still evolving and
there exists no wide accepted definition. Based on
our expertise, we tend to propose an early definition
of Cloud computing as follows:

and released as per user need with least management
effort and human interaction with service provider.”
2.2 Example
A simple example of Cloud computing
concept is Yahoo email, Gmail or Hotmail etc. There
is no need to use software and server to utilize them.
What you need is simply an internet connection and
one can start sending emails. All are available on the
cloud whether server or email management software
and is completely managed by cloud service provider
Yeah, Google etc.
2.3 Cloud Computing Terminology
Cloud Service Provider (CSP) – Cloud
Service Provider is a third party vendor that provides
application delivery, monitoring, hosting and other
services via cloud computing. An organization can
have contractual agreement with multiple CSPs
depending upon the required cloud solutions.
Multi-tenant – Here tenant means single customer. It
provides the ability to share the same application
while running on the same operating system using
same hardware and data storage mechanism.
2.4 Characteristics of Cloud Computing
Cloud Computing offers several features
which are distinct from traditional service computing,
that we summarize below:
On-Demand Self-Service – Resources such as server
time or network space can be accessed and utilize
easily by user when needed, from any place and any
time via global network without human intervention
with service provider.
Broad Network Access – System capacities are
available to customers via the network and can be
accessed from different devices like Desktop
Computers, Mobile Phones, Tablets and Laptops.
Resource Pooling – Computer resources of provider
are grouped in order to serve multiple users using
multi-tenant model. The mechanism of processing
power distribution or amount of memory operated in
such a way that system dynamically assigned these
parameters as per user’s requirements.
Rapid Elasticity – One of the important features of
CC is the computing resources can be provisioned
rapidly and released without human intervention
when no longer needed, thus lower the operating
cost.
Measured Service – CC basically works on the
principle of usage based model and may vary from
service to service. Measured services lower the
operating cost as it charges users on pay-as-you-go
basis.
2.5 Some Existing Definitions
Various definitions have been proposed to
explain the concept of cloud computing. Some of
them are given below as:
According to Wikipedia – “Cloud computing is
Internet based development and use of computer
technology (computing) whereby dynamically
scalable and often virtualized resources are provided
as a service over the Internet. Users need not have
knowledge of, expertise in or control over the
technology infrastructure “in the cloud” that
supports them.”
According to NIST – “Cloud Computing is a model
for enabling ubiquitous, convenient, on-demand
network access to a shared pool of configurable
computing resources (e.g. networks, servers, storage,
applications and services) that can be rapidly
provisioned and released with minimal management
effort or service provider interaction.”
According to the IEEE Computer Society – “Cloud
Computing is a paradigm in which information is
permanently stored in servers on the internet and
cached temporarily on clients that incorporate
desktops, entertainment centers, table computers,
notebooks and handhelds etc.”
According to Gartner Group – “A style of computing
in which massively scalable IT-related capabilities
are provided “as a service” using internet
technologies to multiple external customers.”
According to Fast Cloud Group – “As a new style of
computing in which dynamically scalable and often
virtualized resources are provided as a pay for use
service over the internet or an intranet network.
Users need not have knowledge of, expertise in, or
control over the technology infrastructure in the
“cloud” that supports them.”
According to Armbrust – “Cloud Computing refers to
both the applications delivered as services over the
internet and the hardware and system software in the
datacenters that provide those services”
According to Buyya – “Type of parallel and
distributed system consisting of a collection of
interconnected and virtualized computers that are
dynamically provisioned and presented as one or
more unified computing resources based on Service
Level Agreement.”
2.6 Related Technologies
CC uses the concept of certain technologies
that makes it flexible, reliable and usable. These
technologies are listed below:

2.6.1 Grid Computing
Grid Computing is distributed computing in
which large number of computer from remote areas
which are connected with one another to realize
common objectives. These resources are
heterogeneous and geographically distributed. Grid
computing generally breaks larger tasks into smaller
pieces which are distributed to CPUs residing within
the Grid.
2.6.2 Virtualization
Virtualization is a technique that permits to
share single physical instance of a resource or server
among multiple tenants and organizations. The
multitenant design offers virtual isolation among the
multitude tenants and so the organizations will use
and customize the application like they each have its
own instance running.
2.6.3 Utility Computing
Utility Computing is predicated on pay-per-usage
model. Utility computing provides resources on
demand as a metered service. On demand
provisioning of resources and utility pricing, service
providers can truly maximize exploitation and
assuage their operating costs.
2.6.4 Autonomic Computing
Autonomic computing focuses at constructing
computing system capable of self management that is
behaving according to internal and external
observation without human intervention. The
objective of Autonomic Computing is to overcome
the management complexity of today’s computer
system.
III. LITERATURE REVIEW
Salvatore et al. worked on Service Level
Agreements over Quality of Services (SLA-
QoS) that outlines procedure to provide SLA
based QoS on hazard and risky cloud
environment.
Lee et al. suggest assessing SaaS in a
quantifiable method. For instance, different vendors
can judge the level of various services and can
calculate return on investment.
Wang et al. suggest an automatic
optimization scheme for cloud storage called AOSC
which uses data chunking, placement and replication
to achieve more stable and foreseeable performance.
Younge et al. propose a concept of Green Cloud
structure for increasing efficiency per watt within a
Cloud. The proposed framework utilizes power-
aware scheduling techniques over an exclusive
virtual machine design.
Li et al. presented an approach to find
optimal deployments for huge data centers and
clouds. It applies a combination of bin-packing,
mixed integer programming and performance models
in order to make the taken decisions affect the
various strongly working together goals, which will
include the pleasure of different service level
harmonies for many different applications.
IV. CATEGORIES OF CLOUD
COMPUTING
Cloud Computing can be categorized on two
ways: Location based and on the basis of Service
offered. A Location Based Service refers to the way
in which a customer is offered exclusive services in
terms of geo-location. Another category is on the
basis of Service Offered which explains what type of
service can be obtained from cloud (See Fig. 2).
Figure 2: Classification of Cloud
4.1 Location Based
4.1.1 Public Cloud
In public cloud, a service provider offer
resources as service to a large group of independent
customers such as general public. In public cloud,
services may be offered on a pay-per-usage mode
means cost incurred on the basis of capacity that is
used. Public Cloud also called External cloud.
In other words, public cloud is one in which
computing infrastructure is hosted by the cloud
vendor at the vendor’s premises. Prime example
incorporates Amazon EC2, Google Apps,
Salesforce.com and Microsoft Office 365.
4.1.2 Private Cloud
Also called Internal Cloud, a private cloud is
a cloud in which computing infrastructure is
dedicated to a particular organization. Private cloud
networks is not shared with other organization and
can provide internal services like data storage as well
as external services to the public or other users.
Example of Private Cloud includes Eucalyptus,
Elastra, VMware and Microsoft.
Private clouds are of two types:
On-Premise Private Clouds – On-Premise
Private Cloud is a cloud which is hosted within
an organizations own facility.
Externally Hosted Private Clouds – In this
model, clouds are used by one organization that
is hosted by a third party specializing in cloud
infrastructure.

www.ijera.com 20 | P a g e
4.1.3 Hybrid Cloud
Hybrid cloud is combination of public and
private cloud infrastructures so as to achieve a
maximum of cost reduction via outsourcing whilst
maintaining the desired degree of control over (e.g. –
sensitive data by employing local private clouds).
4.1.4 Community Cloud
Community Cloud is shared by several
organizations and supports a specific community that
has shared concerns. Community cloud may be
managed by the organization or a third party and may
exist off-site. For example, G-Cloud is the special
case of community cloud. This type of service is
provided by one or more agencies, for use of all and
government agencies.
4.2 Service-Offered Based
4.2.1 Infrastructure-As-A-Service (IaaS)
IaaS is a service model that enabled user to
provision processing, storage, networks and other
fundamental computing resources offered to
customer on demand that owned and hosted by
service provider.
In IaaS computing infrastructure, user is
able to deploy and run arbitrary software that can
include applications and operating systems. The
service provider offers too Application Program
Interface (API) that enable the user to start, stop, and
access and configure their virtual servers and storage.
It is also rendered as Utility Computing owing its
utilization of pay-for-what-you-use model. Some of
the popular examples of IaaS Providers are Amazon
EC2 & S3, Microsoft Azure Platform etc.
4.2.2 Platform-As-A-Service (PaaS)
PaaS offers platform layer resources
incorporating software development framework and
operating system support. Google App Engine,
Force.com and Microsoft Windows Azure are some
of example of PaaS.
4.2.3 Software-As-A-Service (SaaS)
SaaS provides on demand applications over
the internet. Some examples of SaaS are
Salesforce.com, SAP Business ByDesign and
Rackspace.
V. CLOUD ENVIRONMENT ROLES
In cloud environment, the roles can be
spotted similar to the role distribution in Service
Oriented Architectures and especially in Virtual
Organizations.
Cloud Providers provide clouds to the customer
either through virtual machines, dedicated APIs or
direct access to resources.
Cloud Resellers aggregate cloud platforms from
cloud providers to provide a larger resource
infrastructure to their customers or to provide
enhanced features.
Cloud Adopters enhance services and capabilities by
exploiting cloud platforms from cloud resellers or
cloud providers.
Cloud Consumers make direct use of cloud
capabilities, however not to reform the services and
capability they offer but to make use of direct results.
Cloud Tool Providers offers supporting tools such as
virtual machine management, programming
environments etc necessary to run the applications.

aggregates Grid services by commercialism their
virtualized interfaces.
6.4 Virtuoso: a system for virtual machine
marketplace
The Virtuoso system is developed by
Northwestern University and aims to make a
marketplace for resource usage.
Resource suppliers may sell their resources to
consumers within the variety of virtual machine and
virtual network. In this era, the customer acquires a
remote virtual machine, memory size, configured
with inclined processor type and data storage
resources. On the basis of need, customer can install
and configure whatever software demanded on
virtual machine.
6.5 COD: Cluster-on-Demand
The Cluster-on-Demand is to use to
implement a virtual cluster with main focus to
separate the cluster usage form the cluster
management. The virtual cluster comprises of subsets
of cluster nodes configured for some common
denotation, involved with user accounts and storage
resources, user specified software environment and a
private network space.
6.6 OpenNEbula
The OpenNEbula is a virtual infrastructure
engine which allows the dynamic deployment and re-
allocation of virtual machines from pool of physical
resources. The OpenNEbula system extends the
advantages of virtualization platforms from a one
physical resource to a pool of resources, decoupling
the server, not solely from the physical infrastructure
however additionally from the physical location.
6.7 Amazon Elastic Compute Cloud
The Amazon Elastic Compute Cloud (EC2)
offers Web service interfaces that deliver resizable
compute capacities to customers in the compute
cloud. Users may rent and configure virtual machines
and data storage readily and exploit the computing
capacities remotely.

Computing using computing clusters and workstation
farms. In addition, it incorporate several interesting
features like compatible interfaces with Amazon’s
EC2, simple installation, deployment and
management, support virtual privet network for users.
VII. STATE-OF-ART TECHNOLOGIES
This section present the state-of-art
implementation and key technologies currently used
for cloud computing.
7.1 Architectural Design of Data Center
Data center provides the facility to house
computer system and associated components such as
processing power and storage. Generally, it
incorporates redundant data communications
connections, redundant or backup power supplies,
environmental controls and security issues.
Design of data center basically follows the
layered approach that has been tested in some of the
deployed data centers (See Fig. 3). The basic layer of
data center constitute from three layers as: Access,
Aggregation and Core layer. In Access layer, servers
in racks physically connect to the network. The
Aggregation layer offers functions like location
service, domain service, server load balancing and
more. The core layer provides connectivity to
multiple aggregation switches and provides a resilient
routed fabric with no single point of failure.
Figure 3: Data Center Design
7.2 Distributed File System over Cloud
This can be perceived from Google File
System (GFS) that is a proprietary distributed file
system developed by Google to provide efficient,
reliable access to data using large clusters of
commodity servers. Files are divided into chunks of
64 megabytes and usually appended to a read and
only extremely rarely overwritten or shrunk.
Comparing traditional file systems, GFS is designed
and optimized to run on data centers to provide
extremely high data throughputs, low latency and
survive individual server failures. Induced by GFS,
open source Hadoop Distributed File System (HDFS)
stores large files across multiple machines. It
achieves reliability by replacing the data across
multiple servers.

7.3 Distributed Application Framework over
Cloud
Google has introduced a software
framework to support distributed computing on large
data sets on clusters of computers called MapReduce.
HTTP-based applications are usually conform to
some web application framework such as Java EE.
MapReduce consists of one Master to which client
applications submit MapReduce jobs. The open
source Hadoop MapReduce project is inspired by
Google’s work. Currently, many organizations are
using Hadoop MapReduce to run large data intensive
computations.
VIII. OPPORTUNITIES
Cloud computing has offering many
benefits. For better understanding we can categorize
them according to fields as business, individuals,
researchers and governments that are summarized
below.
8.1 Opportunities for Business
Businesses will cut back their IT overhead
by migrating computing functions to the cloud. This
might lower value barriers for startup companies by
not requiring expensive IT hardware and
infrastructure purchases within the early stages of
growth. Cloud elasticity additionally permits
businesses to get hold of solely the services and
computing power that they really use. This could
forestall the matter of buying excess infrastructure
capacity which will go unused or having deficient
infrastructure to accomplish key work needs. Cloud
computing may also alter additional businesses in
data-intensive fields to access high supercharged
computing resources, serving to level enjoying field
between smaller and bigger companies.
8.2 Opportunities for Individuals
Cloud computing can offer users with
unlimited access to data files from remote areas using
internet. Modifications that users make to files and
data stored on the cloud from location or device will
be updated when the user accesses the files and data
from different location or device.
8.3 Opportunities for Researchers
CC can enable larger collaboration between
scientists and researchers both domestically and
internationally. It can also offer scientists with more
computing power permitting them to run high-
powered simulations that were previously restricted
solely to those with supercomputing access. CC may
also cut back the quantity of your time that
researchers and scientists got to started IT
infrastructure and increase the time spent on
playacting analysis.
8.4 Opportunities for Federal Government.
CC has ability to cut down federal government IT
expenses by a considerable margin. A big part of the
IT federal budgets is spent on infrastructure and
maintenance. VM migration may greatly reduce these
costs helping to reduce taxpayer funding for these
activities.
IX. RESEARCH ISSUES
Cloud computing has been broadly adopted by many
IT industry as well as business enterprises in recent
times. But the research on it is still at an early stage.
Many existing issues have not been fully addressed
while new challenges keep emerging from industry
applications. Some of the challenging issues of cloud
computing is given below:
9.1 Service Level Agreement
Service level agreement permits many
instances of one application to be replicated on
multiple servers if would like arises. Depending on
priority scheme, the cloud could minimize or shut
down a lower level application. An enormous
challenge for the cloud users is to gauge SLAs of
cloud venders. SLAs to create a defensive defend
against proceedings whereas providing smallest
assurances to customers. So there are some necessary
problems such as information protection, outages and
worth structures that require to be taken under
consideration by the users before signing a contract
with a provider.
9.2 Virtual Machine Migration
Virtualization may provide important
benefits by enabling virtual machine migration to
balance load across the data center. Virtual Machine
Migration permits to move an entire VM from one
machine to another and continue operation of the VM
on the second machine. VM machine migration has
emerged from process migration techniques.
Recently, Xen and VMware have materialized which
incorporates extremely short downtimes ranging from
tens of milliseconds to a second. Most important
advantage of VM migration is to avoid hotspots
however it is not straightforward.
Some of the silent benefits of virtualization in cloud
computing is as follows:
Elasticity and Scalability – Starting up and
shutting down VMs involves less effort as
opposed to bringing servers up and down.
Workload Migration – With less effort, one can
shift the workload by process of migration
instead of workload migration across physical
server at different locations.
Resiliency – One may isolate physical sever
failure from user services through VM
migration.

9.3 Server Consolidation
Server consolidation is an effective method
to maximize resource exploitation while reducing
energy consumption in cloud computing
environment. One approach used to consolidate VMs
is Live VMmigratioin technology that resides on
multiple servers onto single server so that remaining
servers can be set to an energy-saving state. The
problem of optimally consolidating servers in a data
center is often formulated as a variant of the vector
bin-packing problem that is an NP-hard optimization
problem. Several heuristics have been proposed for
this problem.
9.4 Novel Cloud Architecture
Recently, clouds are implemented in big
data centers and operated centrally. However there
are economical pros but it comes along with
limitations such as high energy expenses and initial
investment for constructing data centers. If we talk
about small data centers, it eliminates the problems of
energy, power, cooling system and more over
economical and geographically easily distributed.
Another research is on using voluntary
resources for hosting cloud application. Voluntary
resources assist to create clouds which are better and
most appropriate for non-profit applications like
scientific computing. However it is offering some
benefits but management of such heterogeneous
resources is a challenge and building such
architecture is research problem.
9.5 Energy Management
Another major issue in cloud computing is
to improve energy efficiency. It has been evaluated
that the price of powering and cooling accounts for
53% of the total operational expenditure of data
center. The main objective is not solely to decrease
cost in data centers but to meet government rules and
standards as well.
Designing energy-efficient data centers has recently
received considerable attention. This problem can be
approached from several directions. For example,
energy efficient hardware architecture that enables
slowing down CPU speeds and turning off partial
hardware components has become commonplace.
Energy-aware job scheduling and server
consolidation are two other ways to reduce power
consumption by turning off unused machines. Recent
research has also begun to study energy-efficient
network protocols and infrastructures. A key
challenge in all the above methods is to achieve a
good trade-off between energy savings and
application performance. In this respect, few
researchers have recently started to investigate
coordinated solutions for performance and power
management in a dynamic cloud environment.
X. CONCLUSION
Cloud computing has now been consider as next
generation architecture of IT industry is a talk of the
town these days. The enhancement of cloud
computing is rapidly changing the landscape of
information technology and ultimately turning the
utility computing into a reality. However it offers a
large variety of features but many challenges
incorporating energy management, automatic
resource positioning, information security are only
attracted the research community. There are still
many issues to be addressed.
In this paper, we have surveyed the cloud computing,
state-of-the-art implementation of cloud computing
covering its essential concepts, designing, silent
features, key technologies and research directions as
well. As the development of CC technology is still at
an early stage, we hope our paper will provide better
understanding of the cloud computing and various
research issues thereby bolstering further research in
this field.
