The Way

The Clouds have changed the way services are delivered to companies. The attractiveness of the Clouds comes from the (efficacy) effective gains (cost, performance, availability, fault tolerance...) and agility of enterprise applications and services. The computer infrastructure is becoming a supply chain services. Existing systems of Clouds do not support advanced mechanisms for the optimal trade applications across different Clouds. In this study, the authors proposed an environment consisting of a set of customers with a budget and a number of Cloudlet to process. Before starting the auction procedure, they fit in their separate group, previously formed according to a certain criteria, by paying a registration fee that will be cashed at a local bank in each Club. If a customer does not have enough budget (client in crisis) to satisfy their needs, they can make a bank loan. In this work, the authors propose the way to satisfy Clubs in terms of quality of processing cloudlets (Tasks) for each member of a Club, while minimizing their cost and their time of processing, and the way to integrate the principle of Auction Clubs in CloudSim simulator.

In this chapter we are focusing on reliability, fault tolerance and quality of service in cloud computing. The flexible and scalable property of dynamically fetching and relinquishing computing resources in a cost-effective and device-independent manner with minimal management effort or service provider interaction the demand for Cloud computing paradigm has increased dramatically in last few years. Though lots of enhancement took place, cloud computing paradigm is still subject to a large number of system failures. As a result, there is an increasing concern among community regarding the reliability and availability of Cloud computing services. Dynamically provisioning of resources allows cloud computing environment to meet casually varying resource and service requirements of cloud customer applications. Quality of Service (QoS) plays an important role in the affective allocation of resources and has been widely investigated in the Cloud Computing paradigm.

The Way

Cloud computing is the newest paradigm in computing that turned upside down the way of resource provisioning and payment. Cloud computing improves the resource utilization through virtualization enabling both customers as well as service providers to reap the benefits. Thus virtualization is the enabling technology that made this revolution possible. Through virtualization, it is possible to host multiple independent systems on a single hardware without interfering with each other. Server virtualization techniques can be grouped based how the underlying hardware and operating systems are presented to the users. In this chapter, the author takes an in depth look at how different virtualization has been implemented along with their security and quality of service issues.

The Way

For more than 40 years, fail-fast has been the dominant way of achieving fault tolerance. In this approach, some mechanism is responsible for ensuring that each component is up, functioning, and responding to work. As the industry moves to leverage cloud computing, this is getting more challenging. The way we create robust solutions is under pressure as the individual components don't fail fast but instead, starts running slow, which is far worse The slow component may be healthy enough to say, "I'm still here!" but slow enough to clog up all the work. This makes fail-fast schemes vulnerable.

Cloud computing being a promising paradigm has become very prominent among a wide range of applications due to their timely service rendering capability. Attracted to the type of servicing and the way of servicing lots and lots of users, adapt to the cloud computing. This makes the time servicing of the cloud computing a tedious job. So in order to effectively handle the tasks the scheduling approach is entailed in the cloud computing. The paper proposes an efficient task scheduling for the heterogeneous cloud to render service at a minimized delay utilizing the genetic algorithm. The proposed method is validated through the, cloud simulator to understand the efficiency of the same in terms of delay and the quality of service.

Cloud computing is a resource, as well as an instrument, which in a complex and diverse manner can have an impact on the structure of the factors shaping the competitiveness of supply chains by stimulating their integration and improving the quality of management. By analysing the results of the study in the context of factor and resulting competitiveness identifying the role of cloud computing in the supply chain management, it must be stated that the reasons for its choice interacted with strategic goals. In terms of the impact of cloud computing on the reduction of costs, the respondents mentioned activities associat-ed with the execution of orders, handling complaints and returns, as those where the greatest changes were observed. In the context of the impact on the time of execution of activities and processes, the respondents pointed to: handling complaints time, order ex-ecution time and liabilities payment time. In terms of shaping the quality, the improvement of the timeliness of deliveries, the increase of the level of complete orders delivered to the customers and the improvement of accuracy of demand planning were indicated.

Organizational Compliance

Cloud computing is changing the way organizations approach technology and its infrastructure. However, in spite of its attractiveness, cloud computing can be seen as a threat in terms of compliance. Given its intrinsic distributed nature, regulations and laws may differ and customers and cloud providers must find a way to balance increasing compliance pressures with cloud computing benefits. In this paper, the authors present a framework aimed to help organizations to cope with compliance aspects in their cloud-oriented environments. Built upon current literature on the topic and qualitative approaches, the framework has been implemented in two organizations. Results from its contribution are encouraging, leading to adopter organizations to less reported compliance violations and higher contribution of cloud computing to overall quality of service and organizational compliance management.

This paper investigates whether and at what extent private firms reduce the quality of their accruals in order to signal a better portrait to the bank and obtain new or larger bank loans. We measure earnings discretionary accruals of a sample of Italian private firms, testing whether new and larger bank loans are associated with a higher (lower) quality of earnings in borrowers' financial reporting. We study bank loan levels and changes and how they impact discretionary accruals and found that, surprisingly, private firms' discretionary accruals are systematically positively affected by an increase in bank loans, although they are negatively affected by the credit worthiness rating assigned to the borrowers. We find that the monitoring role of the banking system with regard to the adoption of discretionary accruals is effective only when the loan is very large. This paper may have implications for policy-makers as it contributes to the understanding of the shortcomings of the banking regulatory system. This is an extremely relevant issue since the excessive amount of non-performing loans held by Italian banks recently threatened the stability of the European Banking Union as a whole.
