Service Optimization

One of the major characteristics of our society in the field of information and communication is its efforts to cope with the rapidly changing IT environment. This is probably because firms are closely related to the survival of the company. As a solution to this problem, researches on cloud computing services are being actively conducted. As cloud computing services have emerged in the marketplace, concepts related to IT assets are changing from being owned to using services. Reflecting this trend, many related companies are providing cloud services. Therefore, in this paper, we design an optimized platform for efficient application of server in cloud system environment. To do this, we designed a system to study various system connections based on the cloud computing service environment and implement an optimized service platform. In this paper, we have implemented optimization and virtualization research in a cloud system environment to design a platform for optimized cloud services. In addition, we designed the optimal platform by studying methodologies such as optimization service environment implementation, compatibility and analysis.

This paper aims to alert the board to their duty of adding value to the organizations they represent by recognizing opportunities presented by new developments in information technology. Cloud computing is one such development, which is associated with opportunities and benefits. The service value that can be achieved by using this computing model will be influential in the adoption of cloud computing services. Service value is determined by the warranty and utility associated with that service. Thus, if an organization can associate itself with the utility and warranty on offer via cloud computing, it should consider the adoption of these services. Cloud computing is discussed in terms of service value. This promotes an understanding of factors to be considered when making decisions about the adoption of cloud computing.

Purpose – The purpose of this paper is to explain the role of trust in cloud computing services based on empirical evidence from interviewing executives of financial institutions in Ghana. The paper answers the questions: what is the role of trust in cloud computing service acquisition, and what policies promote trusted cloud computing services? Design/methodology/approach – This is an explanatory paper that is based on literature review and empirical data on exploring reasons for cloud computing service acquisitions. A combination of interviews and focus group discussions was used as methods for data collection. Information technology and electronic banking executives of five major commercial banks in Accra, Ghana, between January and July 2013 were interviewed. A total of ten respondents were interviewed, two in each of the selected banks. A purposive sampling technique was used in the selection of informants. This approach allows the selection of qualified informants to ensure extensiveness and diversity of opinion. Findings – Although previous literature proffers various factors as key to cloud computing adoption, uses or provisioning, this study brings trust to the fore as an imperative for cloud computing service acquisition by financial institutions. It also shows that trust increases if users perceive that cloud computing service providers act in honesty and in users’ interest, making trust a fundamental factor that informs financial institutions’ decision to acquire cloud computing services. Research limitations/implications – The research introduces a new dimension about the widely held perceptions of the factors that influence adoption of cloud computing services. Practical implications – Developers of cloud computing solutions that are targeted at corporate users must focus on systems that enhances their trustworthiness, as it is a primary criteria for user buy-in. Similarly, any trust-building effort by cloud computing service providers minimizes users’ concerns and pushes the services providers closer to the trust threshold. Originality/value – The paper outlines the trust factors that are imperative for cloud computing uses by financial institutions. This is one of the pioneering papers that address trust issues in cloud computing from the perspective of financial institutions.

Cloud computing is a model that aims to deliver a reliable, customizable and scalable computing environment for end-users. Cloud computing is one of the most widely used technologies embraced by sectors and academia, offering a versatile and effective way to store and retrieve documents. The performance and efficiency of cloud computing services always depend upon the performance of the execution of user tasks submitted to the cloud system. Scheduling of user tasks plays a significant role in improving the performance of cloud services. Accordingly, many dependent task scheduling algorithms have been proposed to improve the performance of cloud services and resource utilization; however, most of the techniques for determining which task should be scheduled next are inefficient. This research provided an enhanced algorithm for scheduling dependent tasks in cloud that aims at improving the overall performance of the system. The Dependent tasks were represented as a directed acyclic graph (DAG) and the number of dependent tasks and their total running time were used as a heuristic for determining which path should be explored first. Best first search approach based on the defined heuristic was used to traverse the graph to determine which task should be scheduled next. The results of the simulation using WorkflowSim toolkit showed an average improvement of 18% and 19% on waiting time and turnaround time were achieved respectively.

Cloud Computing is not a revolution; it’s an evolution of computer science and technology emerging by leaps and bounds, in order to merge all computer science tools and technologies. Cloud Computing technology is hottest to do research and explore new horizons of next generations of Computer Science. There are number of cloud services providers (Amazon EC2), Rackspace Cloud, Terremark and Google Compute Engine) but still enterprises and common users have a number of concerns over cloud service providers. Still there is lot of weakness, challenges and issues are barrier for cloud service providers in order to provide cloud services according to SLA (Service Level agreement). Especially, service provisioning according to SLAs is core objective of each cloud service provider with maximum performance as per SLA. We have identified those challenges issues, as well as proposed new methodology as “SLA (Service Level Agreement) Driven Orchestration Based New Methodology for Cloud Computing Services”. Currently, cloud service providers are using “orchestrations” fully or partially to automate service provisioning but we are trying to integrate and drive orchestration flows from SLAs. It would be new approach to provision cloud service and deliver cloud service as per SLA, satisfying QoS standards.

Cloud Computing Services

Cloud computing is a widely used technology that has changed the way people and organizations store and access information. This technology is versatile, and extensive amounts of data can be stored in the cloud. Businesses can access various services over the cloud without having to install applications. However, cloud computing services are provided over a public domain, which means that both trusted and non-trusted users can access the services. Although there are a number of advantages to cloud computing services, especially for business owners, various challenges are posed in terms of the privacy and security of information and online services. A threat that is widely faced in the cloud environment is the on/off attack, in which entities exhibit proper behavior for a given time period to develop a positive reputation and gather trust, after which they exhibit deception. Another threat often faced by trust management services is a collusion attack, which is also known as collusive malicious feedback behavior. This is carried out when a group of people work together to make false recommendations with the intention of damaging the reputation of another party, which is referred to as a slandering attack, or to enhance their own reputation, which is referred to as a self-promoting attack. In this paper, a viable solution is provided with the given trust model for preventing these attacks. This method works by providing effective security to cloud services by identifying malicious and inappropriate behaviors through the application of trust algorithms that can identify on/off attacks and collusion attacks by applying different security criteria. Finally, the results show that the proposed trust model system can provide high security by decreasing security risk and improving the quality of decisions of data owners and cloud operators.
