Cluster computing is a type of computing where a group of several computers are linked together, allowing the entire group of computers to behave as if it were a single entity. There are a wide variety of different reasons why people might use cluster computing for various computer tasks. It s also used to make sure that a computing system will always be available. It is unknown when this cluster computing concept was first developed, and several different organizations have claimed to have invented it.

ADVANCES IN HIGHER EDUCATIONAL RESOURCE SHARING AND CLOUD SERVICES FOR KSAIJCSES Journal
Cloud represents an important change in the way information technology is used. Cloud makes it possible
to access work anywhere anytime and to share it with anyone [1]. It is changing the way people
communicate, work and learn [2]. In this changing environment, it is important to think about the
opportunities and risks of using the cloud in the education field, and the lessons we can learn from the
previous uses of this technology in the education field. In order to gain the benefits of the cloud to be used
in educational system in KSA, a comprehensive study on scientific literatures in this paper. This paper also
presents the significant information such as the findings, the case studies, related frameworks and
supporting also the tools associated to the migration of organizational resources to cloud
A survey-report-on-cloud-computing-testing-environmentshritosh kumar
Cloud computing not only changes the way of obtaining computing resources (such as computers, infrastructures, data storage, and application services), but also changes the way of managing and delivering computing services, technologies, and solutions. Cloud computing leads an opportunity in offering testing as a service (TaaS) for SaaS and clouds. Meanwhile, it causes new issues, challenges and needs in software testing, particular in testing clouds and cloud-based applications. This paper provides a comprehensive tutorial on cloud testing and cloud-based application testing. It answers the common questions raised by engineers and managers, and it provides clear concepts, discusses the special objectives, features, requirements, and needs in cloud testing. It offers a clear comparative view between web-based software testing and cloud-based application testing. In addition, it examines the major issues, challenges, and needs in testing cloud-based software applications. Furthermore, it also summarizes and compares different commercial products and solutions supporting cloud testing as services.
ANALYSIS OF SOFTWARE SECURITY TESTING TECHNIQUES IN CLOUD COMPUTINGEditor IJMTER
Cloud Security Testing is becoming a Popular field of Research Topic in Cloud
Computing and Software Engineering. As the advance of cloud technology and services, more
research work must be done to address the open issues and challenges in cloud security testing and
More innovative testing techniques and solutions, Although there are many published papers
discussing cloud Security testing, there is a lack of research papers addressing new issues,
challenges, and needs in Software Security Testing. however, there is no clear methodology to
follow in order to complete a cloud security testing. Since there is an increasing demand in Software
usage there is more in for Software Security Testing. This paper presents an overview of Cloud
Computing, Cloud security testing and comprehensive survey of security Testing Techniques and
methods. from this we have identified problems in the current security testing techniques. This work
has to presents a roadmap for new testers on the cloud with the necessary information to start their
test.
Authenticated and unrestricted auditing of big data space on cloud through v...IJMER
Cloud unlocks a different era in Information technology where it has the capability of providing the customers with a variety of scalable and flexible services. Cloud provides these services through a prepaid system, which helps the customers cut down on large investments on IT hardware
and other infrastructure. Also according to the Cloud viewpoint, customers don’t have control on their
respective data. Hence security of data is a big issue of using a Cloud service. Present work shows that
the data auditing can be done by any third party agent who is trusted and known as auditor. The auditor can verify the integrity of the data without having the ownership of the actual data. There are many disadvantages for the above approach. One of them is the absence of a required verification procedure among the auditor and service provider which means any person can ask for the verification of the file which puts this auditing at certain risk. Also in the existing scheme the data updates can be
done only for coarse granular updates i.e. blocks with the uneven size. And hence resulting in repeated communication and updating of auditor for a whole file block causing higher communication costs and
requires more storage space. In this paper, the emphasis is to give a proper breakdown for types of
fixed granular updates and put forward a design that will be capable to maintain authenticated and unrestricted auditing. Based on this system, there is also an approach for remarkably decreasing the communication costs for auditing little updates
A systematic mapping study of performance analysis and modelling of cloud sys...IJECEIAES
Cloud computing is a paradigm that uses utility-driven models in providing dynamic services to clients at all levels. Performance analysis and modelling is essential because of service level agreement guarantees. Studies on performance analysis and modelling are increasing in a productive manner on the cloud landscape on issues like virtual machines and data storage. The objective of this study is to conduct a systematic mapping study of performance analysis and modelling of cloud systems and applications. A systematic mapping study is useful in visualization and summarizing the research carried in an area of interest. The systematic study provided an overview of studies on this subject by using a structure, based on categorization. The results are presented in terms of research such as evaluation and solution, and contribution such as tools and method utilized. The results showed that there were more discussions on optimization in relation to tool, method and process with 6.42%, 14.29% and 7.62% respectively. In addition, analysis based on designs in terms of model had 14.29% and publication relating to optimization in terms of evaluation research had 9.77%, validation 7.52%, experience 3.01%, and solution 10.51%. Research gaps were identified and should motivate researchers in pursuing further research directions.
The advancements in cloud computing and leveraging the benefits from
cloud computing to the service providers have increased the deployment of
traditional applications to the cloud. The applications once deployed on the
cloud, due to various reasons, need migration from development
infrastructure to operational infrastructure, one operational instance to other
operational instances due to load balancing and the cycle continues due to the
use of DevOps as development strategies for cloud computing applications.
Advocates of hybrid and public clouds observe cloud computing makes it
possible for organizations to avert or minimize upfront IT infrastructure
expenses. Proponents also assert that cloud computing systems permit
businesses to receive their software up and running faster, using improved
manageability and less maintenance, so it empowers IT teams to rapidly
adapt tools to meet the varying and unpredictable requirements. DevOps is a
lot of practices that mechanizes the procedures between programming
improvement and IT groups, all together that they can fabricate, test, and
discharge programming quicker and even more dependably. The idea of
DevOps is established on building a culture of a joint effort between groups
that generally worked in relative siloes. The guaranteed advantages
incorporate expanded trust, quicker programming discharges, capacity to
explain basic issues rapidly and better oversee impromptu work. Thus, this
work identifies the need for providing multiple security protocols during the
complete life cycle of cloud application development and deployment. This
work proposes a novel framework for automatic selection and deployment of
the security protocols during cloud service deployments. The framework
identifies the need for security aspects and selects the appropriate security
algorithms for virtual machines. The proposed framework demonstrates
nearly 80% improvement over the security policy deployment time.

Cloud computing technology security and trust challengesijsptm
A let of exclusive features such as high functionality and low cost have made cloud computing a valuable
technology. These remarkable features give users and companies, countless opportunities to reach their
goals spending minimum cost and time. Looking at the literature of this technology, it can be claimed that
the main concerns of the users of cloud are security issues especially trust. Unfortunately these concerns
have not been tackled yet. Therefore we decided to introduce a useful and functioned way to create more
trust among consumers to use this technology .In this paper we suggest the foundation of an international
certification institute for the service providing companies in order to increase trust and enhance likeliness
of using this new and valuable technology among people. Practicality of the technology will improve it and
will make its security better by providers.
CHAPTER TWO 13
Literature Review
04/18/2021
Introduction
Cloud computing is taking a central position in many small and medium-sized organizations in Europe after the European Union emphasized improving information and communication technologies. Studies reveal that some small and medium-sized companies opt for other cheaper information communication alternatives due to resource limitations. They may not choose information systems that require a considerable amount of financial resources. A study by (Zissis & Lekkas, 2012) argues that cloud computing involves keeping the infrastructure, data, and applications on the internet to be managed by service providers. The use of cloud computing puts the globe precisely at the fingertips of users. It has elevated competitiveness in the business world and challenges managers to take a strategic move and grab the associated opportunities associated with cloud computing. With its advantages, it is a promising solution for businesses of all sizes. Comment by Brenda Schrantz: Unnecessary word.
Research identifies the key advantages of cloud computing: increased innovation and collaboration, time and cost efficiency, scalability, flexibility, and quick retrieval of data if there is an emergency. Nevertheless, cloud computing is also linked to security and confidentiality matters, compliance challenges, lack of control, and switching costs (Sharma et al., 2017). Over the past few years, cloud computing's adoption has become increasingly significant, considering the internet is one of the most developed infrastructures across the world. Research has also revealed that regardless of the seeming benefits, cloud computing adoption is still unsuccessful in some companies. The potential and benefits of cloud computing are evident, and several empirical studies evidence the progress of adoption in different sectors. This paper analyses existing literature on the aspects that impact cloud computing adoption. Comment by Brenda Schrantz: Sentence fragment
The TOE model will be used as the theoretical framework upon which the hypothesis will be tested.

Survey of uncertainty handling in cloud service discovery and compositionijngnjournal
With the spread of services related to cloud environment, it is tiresome and time consuming for users to look for the appropriate service that meet with their needs. Therefore, finding a valid and reliable service is essential. However, in case a single cloud service cannot fulfil every user requirements, a composition of cloud services is needed. In addition, the need to treat uncertainty in cloud service discovery and composition induces a lot of concerns in order to minimize the risk. Risk includes some sort of either loss or damage which is possible to be received by a target (i.e., the environment, cloud providers or customers). In this paper, we will focus on the uncertainty application for cloud service discovery and composition. A set of existing approaches in literature are reviewed and categorized according to the risk modeling

Security in Cloud Computing For Service Delivery Models: Challenges and Solut...IJERA Editor
Cloud computing, undoubtedly, is a path to expand the limits or add powerful capabilities on-demand with
almost no investment in new framework, training new staff, or authorizing new software. Though today
everyone is talking about cloud but, organizations are still in dilemma whether it’s safe to deploy their business
on cloud. The reason behind it; is nothing but Security. No cloud service provider provides 100% security
assurance to its customers and therefore, businesses are hesitant to accept cloud and the vast benefits that come
along with it. The absence of proper security controls delimits the benefits of cloud. In this paper, a review on
different cloud service models and a survey of the different security challenges and issues while providing
services in cloud is presented .The paper focuses on the security issues specific to service delivery model (SaaS,
IaaS and PaaS) of cloud environment. This paper also explores the various security solutions currently being
applied to protect cloud from various kinds of intruders.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. 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. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

1. PAPER REVIEW
Introduction:
Cloud computing is the use of computing resources that are delivered as a service over a
network. Cloud computing entrusts remote services with a user's data, software and computation.
It is an emerging technology with shared resources, lower cost and relies on pay per use
according to the user demand. It is defined as the delivery of computing requirements as a
service to a heterogeneous community of end-recipients. The available services are mainly
categorized into three classes- Infrastructure as a Service (IaaS), Platform as a Service (PaaS)
and Software as a Service (SaaS).
In recent times, Software as a Service is transformed into a new type of service known as
Software testing as a service (STaaS). It is defined as a model of software testing used to test an
application as a service provided to customers across the internet. It provides testing support
such as load testing, stress testing, performance testing, functional testing, latency testing and
compatibility testing through web browsers.
Though being a comparatively newer field, Cloud Testing has become a point of interest for
many of the researchers and a plenty of research papers have been published. This document
attempts to reflect the motivations and findings of the papers [1] [2] [3]. Besides, the future work
directives and some drawbacks which were observed are also mentioned here.
Review:
#Paper 1: Software Testing Based on Cloud Computing
The paper provided an overall view of cloud testing. Till now, cloud testing is evolving as a new
technology. Thus an overview covering all the prime aspects of the field is required for the
people interested to contribute in it. The paper defines cloud testing keeping the concept of cloud
computing in mind. Moreover it provides answer to some important research questions: Which
software testing can be performed in cloud? Why do we require cloud testing? How can we
perform cloud testing?
1|Page
2. PAPER REVIEW
The paper stated that testing such as, hardware compatibility, software environment
compatibility, software adaptability, functional automation, performance and stress testing can
be performed in the cloud environment. Besides they have identified some of the key reasons of
moving towards cloud testing which includes- cost savings, improved testing efficiency and
more realistic performance testing. However, security vulnerability and inappropriate choice of
testing application is considered as major threats in their writing.
According to this paper cloud testing service can be availed via two methods. One is by using a
web interface and another is by remotely logging into the virtual machine created for the testing
purpose. A general procedure for performing cloud testing was also introduced. The steps are- i)
User Authentication, ii) Choosing appropriate resources and platform, iii) Reviewing the
application and configuring the platform and iv) Payment procedure.
Though the paper had provided a nice overview of the cloud testing field, it didn’t discuss the
methods of collecting the data thus making the given information less reliable. Moreover, the
implementation details were not covered in the paper. A more detailed information regarding the
generalized procedure of cloud testing could have added more value to the paper. Nevertheless,
the paper helped me a lot to gather the basic knowledge regarding cloud testing.
#Paper 2: Research Issues for Software Testing in the Cloud
The paper discussed the research issues of testing in the cloud. It focused on the fact that since
the software development paradigm is shifting towards cloud computing, it implies that the
methods, tools and concepts to test them should also change. Therefore, it is important to
highlight cloud computing research issues from a testing perspective. They solicit an academic
research agenda that puts testing within the fast growing cloud computing context and put up a
good resource for the researchers interested this area. They have selected the grounded theory [4]
approach to discover the research issues for software testing in the cloud. Grounded theory as an
approach aims at the creation of a theory from the collected and analyzed data. For data
collection, they interviewed eleven organizations and the selection of interviewees was guided
by theoretical and snowball sampling. In order to support their results they compared those with
issues gathered from literature.

After analyzing the data they had come up with several issues form three different perspectives-
Application Issues, Management Issues, Legal and Financial Issues. The application issues are-
Applications Suitable for Online Software Testing, Readymade Online Performance Testing
Package for any Customer, Quality Checks for Applications that have been tested in the Cloud,
Harmonization of the Test Processes across Multiple Players and Online Testing Solutions for
Ebusiness Systems. The management issues include- Pool of Testers and Effects on the
Customer’s Business. Finally the Legal and Financial Issues that were discussed are- Test Data
and Pricing Models and Service Descriptions for Testing Services.
Finally, the paper provides some vital research questions which should to be explored: How
cloud software development and testing will affect quality requirements in the future- addressing
the interdependency of cloud software development, cloud testing and overall quality assurance?
How cloud computing, service oriented architecture, open source development technologies and
crowd sourcing affect an organization’s testing process? The paper had identified some of the
key issues of Cloud Testing from three different perspectives. However, it had ignored a major
perspective- Security Issues. Though in some cases they have raised the point of security, the
field itself is so vast that it demanded more attention. Besides it would also be better if they had
highlighted the challenges of implementing cloud platform for business organizations.
Highlighting the challenges might have provided some more research issues in this field.
Overall, this paper was particularly helpful to me as it helped me to gain sufficient knowledge on
cloud testing.
#Paper 3: Blueprint for the Intercloud
– Protocols and Formats for Cloud Computing Interoperability.
This paper deals with interoperability protocols and formats for cloud computing. Major concern
of this paper is how cloud can ensure the interoperability issue. It finds out the order of protocol
that defines the inter cloud operations. It identifies the fields in which implicit interoperability
may be applied. If the idea of implicit interoperability can be implemented in the Cloud Systems,
then the communication among different clouds would be much more subtle and smooth. Clouds
can be residing in different geographies, in the form of any VMs. They can be connected by a

common set of standards if these ideas can be implemented. IP mobility problem would be
removed. Naming, identity and trust issue would be met. There would be a common set of
standards for messaging. Standard for multicasting would be set. When services would move as
payloads, a number of issues arise. Renowned company like Google, Yahoo and Apple use these
interoperability suggestions. So it can be said with confidence that what was stated in this paper
meets industry standard.
It is possible to reproduce some of the aspects discussed in this paper. But it would need
extensive hardware support, as it would need at least two clouds to test interoperability. IP
mobility, naming, identity and trust issues are reproducible through normal network. Some
questions are being focused in the paper like what advantage would bring if implicit
interoperability is implemented, is it really worth trying, what standards should be followed
while setting up clouds, how would we compare different results of different clouds setups etc.
This paper doesn’t mention the cloud setup parameters. If one cloud provider wants to consume
services of other clouds, their functionality must be interpretable. However, this cloud doesn’t
discuss this issue of different types of cloud. This paper would have been more comprehensive if
it would have stated the implementation strategy of Clouds. Issues of IP assignment,
Multicasting etc. aren’t explained in depth.
Implicit communication among clouds can have great impact in the emerging and promising
market of cloud. Further researchers may work on setting a standard for implicit communications
among clouds.
Conclusion:
The objective of this review was to explore the conditions that influence software testing as an
online service and to find the direction for future research. The findings suggest that software
testing as an online service is experiencing a progressive trend. As more and more software
products shift from the traditional desktop form to becoming online services, we can expect that
software testing will follow the same trend. Cloud computing is increasingly becoming the
means through which online services are made available. In view of software testing, cloud
computing presents two avenues whereby (1) the system under test is accessible online or (2)

testing infrastructure is hosted in the cloud for example the testing service mentioned in [1].
Therefore, research regarding online software testing may benefit from advances in cloud
computing. Each of the papers introduces a problem that should be addressed. A thorough
exploration may help to take a more standardized way of cloud testing. Therefore, cloud
computing can be seen as a possible inclusion during future studies.
