Energy-Efficient Resource Allocation for Virtual Service in Cloud Computing Environment

Cloud computing (CC) services can offer substantial cost-effective global operational and relationship benefits if the cooperation between logistics and CC services are resilient. Potential vulnerabilities to cooperation of CC and logistics service providers can occur with respect to vital factors such as security and trust. Extant studies have demonstrated CC benefits as well as few challenges associated with CC services application. However, no extant study has examined the inter-organisational benefits based on cooperative resilience between CC and logistics service providers in terms of both capability and trust vulnerability factors. This study examines the cooperative resilience of logistics and CC service providers based on innovation diffusion theory within a supply chain risk assessment framework. Using structural equation modelling techniques, we investigate the relationship between the vulnerability factor (trust), capability factor (security) and collaboration benefits (relationship and operational) offered by CC service providers based on 236 Chinese logistics service firms’ perceptions of CC adoption. The results indicate Chinese logistics companies perceive security impediments as a major factor affecting cooperative resilience between logistics service and CC service providers.

Job scheduling system problem is a core and challenging issue in Cloud Computing. How to use Cloud computing resources efficiently and gain the maximum profits with job scheduling. Job scheduling system is one of the Cloud computing service providers’ ultimate goals. In this paper, firstly, by analysis the differentiated QoS requirements of Cloud computing resources users’ jobs, we build the corresponding non-pre-emptive priority M/G/1 queuing model for the jobs.Then, considering Cloud computing service providers’ destination which is to gain the maximum profits by offering Cloud computing resources, we built the system cost function for this queuing model. After that, based on the queuing model and system cost function, considering the goals of both the Cloud Computing service users and providers, we gave the corresponding strategy and algorithm to get the approximate optimistic value of service for each job in the corresponding no-pre-emptive priority M/G/1 queuing model. Finally, we also provide corresponding simulations and numeral results.Analysis and number results show that our approach for job scheduling system can not only guarantee the QoS requirements of the users’ jobs, but also can make the maximum profits for the Cloud computing service providers.While the economic case for cloud computing is compelling, the security challenges it poses are equally striking. In this work we strive to frame the full space of cloud-computing security issues, attempting to separate justified concerns from possible over-reactions. We examine contemporary and historical perspectives from industry, academia, government, and “black hats”. We argue that few cloud computing security issues are fundamentally new or fundamentally intractable; often what appears “new” is so only relative to “traditional”computing of the past several years. Looking back further to the time-sharing era, many of these problems already received attention. On the other hand, we argue that two facets are to some degree new and fundamental to cloud computing: the complexities of multi-party trust considerations, and the ensuing need for mutual audit ability.

Moving data and applications to the cloud implies shifting their control from cloud consumers to the cloud service provider (CSP) indefinitely. Hence, the security and privacy (Saamp;P) of the consumers' assets becomes an important issue. Assessing and comparing potential cloud computing (CC) services, poses an issue for CC adopters to choose Saamp;P options that are sufficient and robust at the same time. In this paper, we describe CC adopters' Saamp;P concerns. We identify a set of attributes that reflect various aspects of cloud Saamp;P in an attempt to alleviate those concerns. We classify the attributes based on their tangibility and their relevance to Saamp;P threats. Every attribute in our list is represented by a set of considerations (i.e. polar questions) to assess its quality. We present a tool that embodies our set of attributes. We aim to enable consumers to assess and compare CC services, in terms of Saamp;P, so that they can make well-educated choices. CSPs can also make use of these attributes to offer better cloud Saamp;P.

The lack of confidence in entrusting sensitive information to cloud computing service providers (CSPs) is one of the primary obstacles to widespread adoption of cloud computing, as reported by a number of surveys. From the CSPs’ perspective, their long-term return-on-investment in cloud infrastructure hinges on overcoming this obstacle. Encryption and privacy protection techniques only solve part of this problem: in addition, research is needed to increase the accountability and auditability of CSPs. However, achieving cloud accountability is a complex challenge; as we now have to consider large-scale virtual and physical distributed server environments to achieve (1) real-time tracing of source and duplicate file locations, (2) logging of a file’s life cycle, and (3) logging of content modification and access history. This position paper considers related research challenges and lays a foundation towards addressing these via three main abstraction layers of cloud accountability and a Cloud Accountability Life Cycle.

Cloud computing is a new model for providing computing services, where computing is delivered as a service over the Internet. Cloud computing is a very popular choice among SMEs because computing services are provided at much lower prices compared to their own IT infrastructure. In the cloud computing model, computing services and data storage are outsourced to cloud service providers. Customers do not have full control over applications and their data. Therefore, an added overhead of security risks comes along, and the security of data becomes the primary concern for cloud customers when considering cloud services. This paper explores various deployment models of cloud computing services and IoT (Internet of Things), figures out associated data security issues with them, and suggests a metric-based solution to assess security provided by cloud services.

Cloud computing services have become important to IS/IT recently. Cloud service providers (CSPs) support different types of cloud computing services (Infrastructure as a Service, Platform as a Service, and Software as a Service). There are many challenges and concerns in using cloud computing services that may cause many risks. These risks need addressing while using cloud computing. CSPs provide procedures in order to control risk areas while providing their services. There are many studies that assess risks in cloud computing services. They provide evaluation tools and/or frameworks to manage the risk in cloud computing services. Moreover, IS/IT governance is one of the most powerful ways to achieve IS/IT business alignment. The main goals of IS/IT governance are to ensure that the investments in IS/IT generate business values and to mitigate the risks associated with IS/IT. Even though there are various risks in cloud computing services, there is no comprehensive framework to support risk assessment according to user’s needs. In this paper, we aim to provide a conceptual framework for governance in cloud computing services. This framework will focus on cloud client (CC) requirements to achieve the governance.KeywordsCloud computingGovernanceRisk assessmentSLARisk control

Cloud computing is an emerging information technology (IT) paradigm which undoubtedly has received significant attention from different spheres of influence. The cloud computing concept entails the provisioning of computing resources from remote locations to individuals or organizations over the internet at anytime. The technology is associated with several benefits but the reduction in capital and operational expenditure is the major one. The importance of IT innovations to Small and Medium Enterprises (SMEs) and the role of SMEs in economic growth have been demonstrated empirically. However, literature indicate that SMEs in developing economies are not taking the advantages of emerging technologies like cloud computing to improve operational excellence within their organizations. An in-depth review of academic publications, technical reports, and industry white papers on cloud computing has confirmed security and privacy is-sues as some of the key inhibitors to cloud computing adoption among SMEs. This is probably because the customer data is released to remote locations, which are invisible, and data is accessed over the internet, which is already over-whelmed with malicious attackers. This study explores the reasons for the lack of cloud computing adoption among SMEs in developing economies. When the rea-sons for this lag are identified, cloud computing service providers, technology policy makers, entrepreneurs and SMEs executives will be provided with the opportunity to develop appropriate solutions and strategies that will specifically meet the needs of SMEs in developing economies. This will promote and accelerate the acceptance rate of cloud services. When SMEs utilize cloud computing as an IT strategy, business growth becomes inevitable and the country's economic growth is witnessed.

Although software and computing process have long been regarded as products among consumers (Armbrust et al., 2010; Skiba, 2011), the advancement of technologies (e.g., high-speed internet) and infrastructures leads to the notion that software and computing can be delivered as a type of service through an innovative technology called cloud computing. Cloud Computing Service (CCS) delivers applications and processing as services via the Internet, while the software and data are stored on servers at a remote location (Armbrust et al., 2010). In other words, under the context of CCS, software and computing process have become a utility such as electricity and water. Advantages of CCS include reduced investment in hardware and software, immediately elevated performance, etc. CCS is believed to be a billion dollar market and growing (Buyya, Yeo, Venugopal, Broberg, & Brandic, 2009). Nevertheless, CCS will reshape the way in which consumers perceive software and computing process (Armbrust et al., 2010) and make purchase decisions. How the notion of CCS diffuses among individual consumers remains unexplored.

Cloud computing is founded by the concept of service computing, where everything is a service--computing services are now utilities. There are various known services in cloud computing. At the moment, there are Software as a Service (SaaS), Platform as a Service (PaaS), Hardware/Infrastructure as a Service (HaaS/IaaS), and Database as a Service (DaaS). In this paper, we propose Ontology as a Service (OaaS), which is an ontology tailoring process service in the cloud. In particular, we focus on sub-ontology extraction and replacement on the cloud. We use the Maximum Extraction method to facilitate this. UMLS meta-thesaurus ontology is used as a walk-through case study to illustrate our proposed method.

The concept Cloud computing has not only reshaped the field of distributed systems but also fundamentally changed how business potential extends today. In recent advancements, Cloud computing applications are provided as services to end-users. The application services hosted under Cloud computing model have complex provisioning, configuration, and deployment requirements How to use Cloud computing resources efficiently and gain the maximum profits with efficient utilization of resources is one of the Cloud computing service providers' ultimate goals. Repetitive evaluation of the performance of Cloud provisioning policies, application workload models, and resources performance models in dynamic system are difficult to achieve and rather a time consuming and costly approach. To overcome this challenge, Cloud analyst simulator based on Cloud Sim has been proposed which enables the modeling and simulation in cloud's ambience. The objective of this paper is to prove that the choice of VM Scheduling Policy in Cloud computing model significantly improves the application performance under resource and service demand variations. We will discuss different Virtual Machine (VM) Scheduling Policies implemented and their performance analysis in Virtual environment of cloud computing in order to achieve better Quality of Service (QoS).

Cloud computing is a promising computing model that enables convenient and on-demand network access to a shared pool of configurable computing resources. The first offered cloud service is moving data into the cloud: data owners let cloud service providers host their data on cloud servers and data consumers can access the data from the cloud servers. This new paradigm of data storage service also introduces new security challenges, because data owners and data servers have different identities and different business interests. Therefore, an independent auditing service is required to make sure that the data is correctly hosted in the Cloud. In this paper, we investigate this kind of problem and give an extensive survey of storage auditing methods in the literature. First, we give a set of requirements of the auditing protocol for data storage in cloud computing. Then, we introduce some existing auditing schemes and analyze them in terms of security and performance. Finally, some challenging issues are introduced in the design of efficient auditing protocol for data storage in cloud computing.

Cloud computing (CC) has many benefits, so its use has spread rapidly, particularly in the business sector. An important consideration in the acceptance of CC is whether the CC system is dependable, and it can differ among industry and service type. However, little research has considered the effect of dependability (composed of availability, reliability, security, maintainability) on CC acceptance. Especially, group comparisons between high IT-intensive (Hi-ITi) and low IT-intensive (Lo-ITi) industries have not been reported, nor have comparisons between software-as-a-service (SaaS) and platform-as-a-service (PaaS)/infrastructure-as-a-service (IaaS). This study aims to explore how the dependability of CC affects users’ intent to accept it, with focus on how this intent is affected by intensity of IT use (by industry) and by the type of CC service used. To validate the proposed model, this study applied structural equation modeling and conducted multi-group analysis. A total of 230 business managers in South Korea represent the sample for our study. For the full dataset, the three dependability attributes (availability, reliability, security) do not affect the usefulness of CC, but do affect the ease of use of CC. The usefulness of CC is a determinant for positive intention to accept CC, whereas the ease of use of CC is not. Maintainability is the strongest determinant of CC adoption for the full dataset, and for all individual groups, except those that use SaaS. For Hi-ITi and Lo-ITi industries, results show that managers show no differences in their perceptions of the effect of dependability attributes (availability, reliability, security) on the usefulness and the ease of CC. The absence of such a difference in managers’ perception also applies to the relationship between two core variables of TAM (i.e., perceived usefulness, perceived ease of use) and behavioral intention to accept CC. For SaaS and PaaS/IaaS, managers have different perceptions of security on the usefulness of CC, and the effect of the usefulness of CC on the intention to accept CC. The findings can provide academic researchers and industry practitioners with a differentiated and in-depth perspective on the understanding and the spread of CC.

Cloud Computing, Mobile Technology, and Social Networking Services such as Facebook and Twitter has become an integral part of society during the event of an emergency or disaster. In the wake and aftermath of a disaster, a tremendous number of people used social networking sites to post and share information. The Department of Health and Human Services (HHS) had sponsored a challenge for software application developers to design a Facebook application to help people prepare for emergencies and to obtain support from friends and families during its aftermath. Lockheed Martin had responded to this challenge by creating a cloud and mobile based Facebook application called the Personal Emergency Preparedness Plan (PEPP). This paper discusses the design and integration of the PEPP Facebook App with the intention of serving as reference architecture for developing social networking applications using cloud computing and mobile technology.

Cloud computing is the most important part of today's information technology world that provides solutions to almost all the sectors for improving their business. This innovation helps organizations to enhance or redesign the services at a very low expense. This study investigates the integrated factors that impact in adopting Cloud computing technologies in banking industries in order to adopt innovation benefit. In this paper, the quantitative analysis were performed based on the questioners and answers given by 2358 banking industry related persons like bank managers, customers, higher management. The questionnaire is based to identify their opinion for the adoption of cloud computing for services in banking industry. Benefits and challenges of cloud adoption in banking industry are also identified. We have proposed a cloud adoption framework Cost, Organizational, Technological, Environmental and Decision-maker (COTED) factors. The findings of this research have revealed that all the identified factors have a significantly effect on the adoption of cloud computing technologies for banking industry. With the findings, cloud computing service providers will have a better understanding of what factors are most influencing for cloud computing adoption with relevant insight on current promotions.
