ADOPTION OF CLOUD-BASED SERVICES BY SMEs IN DEVELOPING COUNTRIES: DEVELOPMENT...Amos Wachanga
Small and Medium Enterprises (SMEs) face numerous challenges in identification, setting up
and making use of Information Technology (IT) as an enabler for business. Cloud computing
could solve this problem by offering ready, low cost of entry IT solutions. Adoption of cloud
computing among the SMEs in developing countries is however low due to a number of
barriers as identified by previous studies. Over the years, research on adoption on innovation
and technology has unveiled a number of theories on adoption which range from Individual
level theories to Organizational level theories and even Market level theories. This study
reviews the various theories, opting to use an organization level theory so that focus on the
SME is emphasized. Analysis of literature renders this study to be based on the Technology-
Organization-Environment (TOE) framework proposed by DePietro et al. (1990). This study
reviews the current adoption levels of cloud computing and proposes a TOE based model for
adoption of cloud-based services by SMEs in developing countries. The study employed
literature review to determine the factors that are applicable for a model on adoption of cloud
computing in the developing countries. Further, the study conducted a survey through a
questionnaire to collect quantitative data to assist in determination of the most applicable
model. Convenience sampling was employed due to the study’s constraints on time and budget.
The study findings revealed that there is low adoption of cloud computing for business
applications by SMEs in Nairobi County, hence confirms the need for the adoption model.
Using Exploratory Factor Analysis (EFA) six components were extracted for the proposed
model which include Relative Advantage, Accessibility, Organization Readiness and Size,
Vendor Readiness, Regulations and Trading Partner Pressure, each with attributes required to
ensure successful adoption of cloud computing. The model was validated through statistical
analysis which confirms a largely reasonable level of fit for the indices and construct validity
conducted through convergent and discriminant validity methods. Further, the model was
subjected to experts’ analysis who concluded that the model is simple, applicable and fitting.
The study finally proposes practical recommendations to governments and policy makers,
educational institutions, software vendors and SMEs based on the model. Further research
areas include subjecting the model to larger sample sizes to confirm its validity and the
preparation of an implementation guideline.

EXPLORATION OF INSTITUTIONAL CHALLENGES FOR ADOPTING CLOUD COMPUTING IN E-LEA...IAEME Publication
Cloud computing is a new on-demand delivery of software and hardware resources to consumers over the internet. It has been proposed as a preferred solution for future systems of education. Furthermore, using cloud computing grows rapidly on various applications in different education fields such as E-learning. It has become a critical point on any institutional deploying, creating a remote educations system and designing of the perfect web-based learning environment. Cloud computing is distinguished by providing large storage resources with cost savings and faster data transfer. Nowadays, data of several social networks (photos, music, videos etc.) are stored in their own purchased cloud. As a consequence of using these applications, cloud computing is indirectly used is our life. Therefore, cloud computing (or cloud technology). In other words, the services that one can easily access these applications in electronic devices is called cloud computing.
E-learning systems basically require many software and hardware resources to implement education tasks effectively. Therefore, adopting available cloud-based application can make the tasks more affordable. Cloud offers the opportunity to work from anywhere and combines software, hardware and hosting services in a single structure with a technology that collects solutions for organizations. To achieve this goal, it facilitates the operation by enabling customers to reach the same data simultaneously. This article, thus, investigates barriers to implement cloud e-learning adoption in Iraqi education institutions.

AN EMPIRICAL STUDY OF USING CLOUD-BASED SERVICES IN CAPSTONE PROJECT DEVELOPMENTcsandit
Cloud computing is gaining prominence and popularity in three important forms: Software as a Service, Platform as a Service, and Infrastructure as a Service. In this paper, we will present
an empirical study of how these cloud-based services were used in an undergraduate Computer Science capstone class to enable agile and effective development, testing, and deployment of sophisticated software systems, facilitate team collaborations among students, and ease the project assessment and grading tasks for teachers. Especially, in this class, students and teachers could leverage time, talent, and resources collaboratively and distributedly on his/her own schedule, from his/her convenient location, and using heterogeneous programming platforms thanks to such a completely All-In-Cloud environment, which eliminated the necessity of spending valuable development time on local setup, configuration, and maintenance, streamlined version control and group management, and greatly increased the collective productivity of student groups. Despite of the relatively steep learning curve in the beginning of the semester, all nine groups of students benefitted tremendously from such an All-In-Cloud experience and eight of them completed their substantial software projects successfully. This paper is concluded with a vision on expandin and standardizing the adoption of the Cloud ecosystem in other Computer Science classes in the future.
Cloud computing has sweeping impact on the human productivity. Today it’s used for Computing, Storage, Predictions and Intelligent Decision Making, among others. Intelligent Decision-Making using Machine Learning has pushed for the Cloud Services to be even more fast, robust and accurate. Security remains one of the major concerns which affect the cloud computing growth however there exist various research challenges in cloud computing adoption such as lack of well managed service level agreement (SLA), frequent disconnections, resource scarcity, interoperability, privacy, and reliability. Tremendous amount of work still needs to be done to explore the security challenges arising due to widespread usage of cloud deployment using Containers. We also discuss Impact of Cloud Computing and Cloud Standards. Hence in this research paper, a detailed survey of cloud computing, concepts, architectural principles, key services, and implementation, design and deployment challenges of cloud computing are discussed in detail and important future research directions in the era of Machine Learning and Data Science have been identified.
Maintaining Secure Cloud by Continuous Auditingijtsrd
Increases in cloud computing capacity, as well as decreases in the cost of processing, are moving at a fast pace. These patterns make it incumbent upon organizations to keep pace with changes in technology that significantly influence security. Cloud security auditing depends upon the environment, and the rapid growth of cloud computing is an important new context in world economics. The small price of entry, bandwidth, and processing power capability means that individuals and organizations of all sizes have more capacity and agility to exercise shifts in computation and to disrupt industry in cyberspace than more traditional domains of business economics worldwide. An analysis of prevalent cloud security issues and the utilization of cloud audit methods can mitigate security concerns. This verification methodology indicates how to use frameworks to review cloud service providers (CSPs). The key barrier to widespread uptake of cloud computing is the lack of trust in clouds by potential customers. While preventive controls for security and privacy are actively researched, there is still little focus on detective controls related to cloud accountability and auditability. The complexity resulting from large-scale virtualization and data distribution carried out in current clouds has revealed an urgent research agenda for cloud accountability, as has the shift in focus of customer concerns from servers to data.

Cloud computing (CC) implementation for educational services is
confronting several challenges. Prior research focused on the technological
related challenges while few examine the economic challenges. The purpose
of this study is to examine the economic challenges for using CC in
educational institutions in Iraq. Articles pertaining to the topics were
extracted from main databases. Based on the review, the critical challenges
were identified. To confirm their relatedness to Iraqi context, a questionnaire
related to the challenges was developed. A total of 204 respondents working
as IT professional has participated in this study. The findings showed that the
challenges mainly related to the infrastructure readiness, internet connection,
cost of establishing and managing the CC. The challenges were divided into
three phases. The pre-implementation phase includes the challenges of
selecting service provider and deployment as well as the readiness of
stakeholders, training, and infrastructure readiness. The implementation
phase includes the challenges of maintaining the bandwidth, compatibility,
legacy system, internet connection, reliability, availability, connectivity, and
management. The post-implementation phase includes the challenges of
security, privacy, quality of education, switching cost, and lock-in. The most
critical challenges in all phases are related to infrastructure readiness, internet
connection, switching cost and management of CC. The findings were
discussed and limitations of the study as well as the direction for future
works were given.

A Framework for Cloud Computing Adoption in South African GovernmentGovCloud Network
Technology adoption is always a critical concern in organizations (private and public). South African government experienced this encounter when adopted Open Source Software (OSS) with the objective to reduce ICT services costs among others. The implementation of OSS in SA government has faced several challenges such as user resistance, human factor, support and funding. As a result of these challenges cost reduction has not been fully achieved. Cost reduction issue ultimately affects implementation of other government programmes such as those who yields job creation, better education, and improving health, etc. The potential alternative to address the same objective as aimed by OSS is Cloud Computing adoption. Cloud Computing promise to offer the SA government more advantages OSS. This study explore the feasibility of Cloud Computing adoption as an alternative to enable cost reduction, effectiveness and efficient of IT services in SA government as was aimed by OSS initiative.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Rainfall intensity duration frequency curve statistical analysis and modeling...bijceesjournal
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.

ABSTRACT
Internet traffic has become vast in terms of data processing as well as storage which has occurred some
limitations on existing traditional infrastructure. Such limitations may include servers, data storage, and
computing resources. This has consequently led most of organization to keep investing and expanding their
infrastructure in periodical phases. Hence, two factors are always co-related to each other which are
TCO (total cost of ownership) and ROT (return on investment) which are critically increased due to the
amount of general investment including all expenses as well as human powers. Therefore, a new technology
has emerged which is called “Cloud Computing”. This terminology has been released recently to work as a
supportive to traditional infrastructure which is part of Datacenters. It offers reliability, improved QoS,
and efficiency to end-users. This paper presents a novel case study of cloud computing on a large scale
environment. Various factors such as TOC and ROI have been taken in consideration on a comparative
study with traditional Datacenter. Results have shown considerable improvement on performance,
utilization, and investment.

1. INTRODUCTION
Technology is growing very rapidly towards various directions of innovation including
computing and resources. Such development is a key pointer of the massive increase on internet
traffic and lack of resources [11] [12] [13]. Therefore, business is moving behind ways of saving
computing resources on a low cost effective wise [14]. However, organizations have become
more advanced on delivering services and running their infrastructure against some limitations of
budget and cost. To narrow down the subject, educational sector is one of the largest sectors that
seek state-of-art solutions on building IT infrastructure, with maximum low cost effect.
In educational sector, there are many of the running systems on different levels such Students
Information System (SIS) ,HR system, ERP (Enterprise Resource Planning), and eLearning
systems. These systems acquired higher demand on bandwidth and computing resources, and
most importantly require high availability. Legacy infrastructure has shown some limitations as
shall be shown on the rest of this paper. Systems upgrades of software and hardware are
imperative items on such organizations’ resource meetings and it is always be a pressure on the
budgets. This situation is likely to be became worse in nowadays financial crisis.
Cloud computing has emerged as a new technology on late 2007 [1] [15] [16] and since then it
has shown to be an upcoming topic of research owing to the ability of granting dynamic
infrastructure on various levels such as services and computing resources. Different paradigms
have shown to present such technology such as grid computing, cluster computing and eventually

cloud computing [17] [18]. More emphasis has been given to the latter which is “Cloud” [19]. It
has given more potentials to the owner of business and normal users to access their needs at
anytime, anywhere based upon their demand without running their own infrastructure [20].
Certainly, cloud computing has proven to be attractive to academic institution [21]. Universities
are always looking to upgrade their software and IT hardware in order to meet students and staff
requirements with the rapid developments in digital technologies. Cloud computing is an option
to achieve such motivations with budget affordability [23].
Over the last few years, many companies have used clouds to build highly scalable systems.
However, cloud computing is not just for start-ups; enterprises are attracted to cloud-based
services as cloud providers market their services as being superior to in-house datacentres in
terms of financial and technical dimensions e.g. more cost effective, equally or perhaps more
reliable, and highly scalable.[1,2,22].
This paper presents a novel case study of how cloud computing could be an optimum solution for
educations, and essential to note that which cloud solution is better is out of the scope of this case
study. Moreover, Migration of University of Hail Data centre to private cloud and potential
benefits of private cloud computing concept which become evident: better control, access,
security and efficiency than today’s data centre with the agility required for business innovation
at substantially lower costs from virtualization is also presented.
2. RELATED WORK
Cloud computing has been shown recently on research areas, so not much studies have been
carried out on this new trend of technology in terms of case studies. However, cloud computing
as a technology has been looked at from different angles. For instance in [7], the authors define
cloud services and offer insight into architecture and how it could be leveraged for virtualization.
Moreover, authors have given insight into on market-based resource management strategies that
embrace both customer-driven service management and computational risk management to
sustain Service Level Agreement (SLA)-oriented resource allocation.
Authors in [8] has given more emphasis on concept of cloud computing and some of the issues
that cloud could address as new technology. Also it has given an idea of what research topics
would be considered on implementation of cloud today.
However, cloud establishment has been considered on [9] as several general examples of cloud
users were provided and a case study of the University of Westminster was presented in details. It
was shown that educational establishments are most likely ready to take over cloud computing
due to funding issues and economic crisis.
Cloud computing deployment in educational sector has been surveyed by [10] and in particular at
university of California (UC) at Berkeley. It was shown that cloud is very handful to use on their
teaching materials where all courses were migrated into cloud instead of being stored locally.
In contrast to abovementioned studies, this paper presents a novel case study looking at
performance of real cloud experience at educational sector. Furthermore, a comparative study
with aging old traditional data centre is presented. Considerable factors have been examined on
both environment to gauge cloud performance and advantages over traditional servers and
storages.

population and under E-Government initiative, the UoH has many successful implementation of
Eservices and advanced information Systems (SIS, ERP, ECM, BPM) to achieve excellence in
research and academics, as well as higher administrative efficiency. However, this has put a lot of
pressure on old UoH data centre to cope with such rapid transformation and had been failing
behind due to having aging physical infrastructure.
3.2.2. Aging and Accidental Infrastructure
Old data Centre comprised of 60+ physical servers, with an average age of six years (some up to
8-years-old). Most of these servers are facing hardware reliability and had reached capacity.
Disaster recovery capabilities were very limited, relying on old fashion for backup. Furthermore,
in case of server failure, then another had to be procured and physically deployed in its place.
This consequently would require time and cost where services cannot be interrupted at all due to
having various research experimental labs ongoing as well as other critical departments working
full-time. Moreover, Recovering data and applications were difficult and time-consuming
exercises.

3.2.3. Management and Operational Complexity
Traditional data centre requires intensive management and maintenance; hence, university’s IT
staff time and efforts mostly spend on troubleshooting and keeping the services up and running
as shown in figure 1. IT was extremely short of the resources to expand the infrastructure rapidly
enough to meet the SLAs and community’s high expectations. Furthermore, such legacy
environment is a key cause of not getting more innovation and creativity from IT staff due the
fact of always being busy on managing and monitoring whole infrastructure.
3.2.4. Total Cost of Ownership (TCO)
Maintaining these diverse technologies became difficult and costly. Acquiring together new
technologies on our own was extremely risky, complex and time consuming. Any iterations or
additional nodes were always costly across levels. Additionally, single point of failure was a
critical issue for legacy data Centre due to the fact of not placing many physical servers due to
budget constraints and cost.
Therefore, the university was in need of migrating to a solution that offer rich virtualization and
cloud capabilities while freeing our administrators to focus more on innovation.

3.3. CLOUD BASED SOLUTION
Could computing has been offered on various models by different vendors. Each and every
vendor is looking at cloud from certain viewpoint which gives more innovation and new trend.
Hence, in order to adapt such technology, it was essential to survey as many as possible offered
solution on cloud-based, taking into consideration university demand and budget limitation.
However, after studying the existing architecture and the business requirements, it is found that
there are solutions available for public and private cloud as shown in below in figure 2.
Figure 2 Some of the available solutions

After studying available solutions, it was evident to the IT management that most of available
solutions are capable to handle university needs and demand. However, since the aim of this
paper is to show how cloud perform over traditional servers and infrastructure. On the other hand,
answering the question of which solution is better is out of the scope of this case study. Therefore,
university has selected VCE solution which is called VBlock. UoH has deployed a Vblock
System 720 which is pre-tested, pre-engineered, and pre-configured. Within 4 days of powering
up the Vblock System, applications were running. The entire migration was completed in four
weeks. The Vblock System now provides the performance, reliability, agility and simplified
management needed to support UOH’s expansion. Applications running on the Vblock System
are fully virtualized.
Figure 3 Vblock Solution [4]
The Vblock System has provided the performance, reliability, agility and simplified management
needed to support UOH’s expansion. The infrastructure hosts MS SQL Server, Oracle RAC, MS
SharePoint, MS Exchange and Core business applications Academic SIS, Oracle ERP and .Net
based E-Services. The applications are all running on the Vblock System are fully virtualized.
Figure 4 shows how the selected solution is structured and joint together as one component. It
clearly shows how private cloud could be built and fully virtualized, not only this but pool of
resources are all managed from a single console.

4. PERFORMANCE EVALUATION AND RESULTS
In order to compare between the new deployed infrastructure on cloud platforms versus tradition
infrastructure, experimental work has been conducted on two different datacentre at university of
Ha’il. However, it is essential to convey that environment have been similarly run on two
different sites with similarities on applications and systems deployed on both sites. Therefore, in
order to gauge and validate the performance of both trends, various factors have been considered
which are shown on the following:

4.1. Smaller Footprint
Private Cloud implementation sped deployments, increased IT productivity, enhanced agility,
saved capex and opex, and enabled staff to spend more time for R&D, and achieve user
satisfaction. IT is now a key enabler of UOH’s growth and educational objectives. Small foot
print to save energy, space Consolidated server equipment racks down from 13 to 6, Physical
servers from 65 server to 24, so hardware occupies 50 percent less resources in the data centre.
Figure 5 gives a clear insight between traditional datacentre (a.k.a pre-cloud) and Cloud based
solution. It has been noticed that ac clear reduction in acquisition/maintenance expenditures on
hardware (servers, storage, network, etc.) and software are saved by 40%, servers by 63%, and
power by 50%; not only that but also It has reduced facilities space requirements by 53%.
Therefore, such valuable diversification among two paradigms would surely encourage public
and private sectors both to migrate and join the cloud era.
Figure 5 Smaller Footprint
4.2. Predictable Performance
Performance is a key factor on IT environment; hence, systems are always gauged by their
capability and scalability on performing and responding very prompt on end users or business
requirements. Thus, in order to achieve high performance with high availability, cloud solution
has been recently a trend to accelerate and boost up processes on IT environment. On this case
study, It has been found out and investigated that virtualisation is taking place on the new
environment up to 100 percent of UOH Tier 1 applications which maintains high service levels
for roughly 40,000 users. Therefore, the Private cloud has shown easily critical workloads, the
resources to get the required response times, especially for critical applications such registration,
payroll, and other demanding systems. Not only this but also database lookups now get
millisecond responses. Furthermore, Private cloud has proven to keep running without downtime,
at incident of any hardware failure, this is backed-up on a virtual server replication which offers
high availability up to 99.99. Figure 6 shows a comparative measurement between pre-cloud
scenario and cloud paradigm. It is very obvious that cloud ( which is adapting Vblock solution)
has proven very clear reduction in terms of server incidents due to redundancy offered by
virtualisation. Furthermore, time cost for fixing or returning any single server back to normal is
consuming very long time whereas on cloud solution is easily figured out from a single console
management system.

Figure 6 Downtime Measurement
It is also worth mentioning that predictable performance has also enabled UOH to virtualize key
databases with confidence, including SIS, Oracle ERP, ECM databases, which are accessed by its
customers on a 24x7 basis. Use of Storage Virtualization provisioning technology FAST VP and
thin-provisioning improved resource utilization and increase performance.
4.3. IT efficiency
The private cloud platform provides UOH to manage everything from a single console. UOH
estimates the division’s three-member IT team regained 60 to 70 percent of the time spent
managing their older systems. With the efficiency gains enabled by an integrated, virtualized
infrastructure and consolidated support model, UOH IT has significantly more time to focus on
innovative projects to promote the university’s long-term vision for Academic excellence.
Growing from 4 to 90 terabytes business data with no increase in IT Staff and freeing more time
for IT to focus on delivering solutions instead of troubleshooting.
New Sever provisioning is 20x time faster than was on legacy infrastructure. New virtual servers
can be provisioned in round 15-20 minutes, compared to several hours or even days using the
previous physical infrastructure.
Figure 7 depicts estimated cost the two scenarios (pre-cloud and cloud), It is obviously shown
that cloud based solution is in a position to save a lot of cost for any organisation if they plan
migration to cloud very carefully.

4.4. Operation and maintenance
This section gives another insight of various evidences have been figured out by the conducted
study towards cloud trend in terms of different factors. Below figures are Comparing old vs.

Cloud based solution’s Operating Saving with respect to operation cost, management saving,
operation saving, investment and saving flow and finally Total Cost of Ownership is considered.
By simplifying operations, the Cloud based solution provides significant cost savings across
different data centre operating cost categories over the five year period as indicate in figures 8
and 9 below. Furthermore, cloud solution implies an early capital outlay, the benefits over time
add up as indicated by figure 11 below. Overall, It is apparent that the benefits of private cloud
computing concept have become evident: better control, access, security and efficiency than
today’s data centre with the agility required for business innovation at substantially lower costs
from virtualization as shown in figure 10 and 12. Therefore, If any sort of business requires
multiple IT services, no longer needs to assemble your own hosting/support/provisioning,
management tools, or planning equipment for future growth, cloud has shown efficient
performance over traditional legacy heterogeneous servers.

5. CONCLUSION AND FUTURE WORK
This paper has contributed to the fields of cloud area by pure raw case study comparing and
testing the performance of cloud over traditional servers. Cloud computing is a disruptive
technology that is set to change how IT systems are deployed because of its apparently simple
and scalable nature. The findings of this case study show that cloud computing can be a
significantly cheaper alternative to purchasing and maintaining system infrastructure in-house.
Furthermore, cloud computing could potentially eliminate many support-related issues since there
would be no physical infrastructure to maintain. Despite these advantages, this case study has
showed that there are important socio-technical issues that need to be considered before
organizations could migrate their IT systems to the cloud. Finally, the system infrastructure in the
case study has evidently shown Operating Costs 74% over 5 Years , 8% saving on management
,and 63 % on cash purchase.
