TL;DR: A novel methodology termed as service insurances is proposed, which is incorporated into the service broker as a new module and is expected to ensure customer’s satisfaction in context of a business application domain.
Abstract: In cloud service domain, an acceptable standard of quality of service (QoS) must be maintained for subscribed services. The performance measurement of those cloud services is based on the satisfaction of customers with respect to the pre-defined QoS. Deviation of QoS as mentioned in SLA results dissatisfaction among users. A large numbers of business entities and consumers are involved in this service delivery process. In business environment, guaranteeing the QoS and establishing the service contracts are essential. However, for the service providers, it is challenging to maintain the QoS at run-time. Moreover, even if it is maintained, additional cost may be needed. Sometime a categorization among the consumers (premium or ordinary) is also required due to the limitation of the resources. Thus, the service management for ensuring the delivery with desired QoS at least for the premium consumers is necessary. This paper proposes a novel methodology termed as service insurances, which is incorporated into the service broker as a new module. The proposed concept is expected to ensure customer’s satisfaction in context of a business application domain.

TL;DR: This paper reviews the recent approaches that have been introduced and used for cloud service brokerage and proposes a set of attributes for a CSB to be considered effective, which have wider application in cloud computing environments.
Abstract: Cloud computing users are faced with a wide variety of services to choose from. Consequently, a number of cloud service brokers (CSBs) have emerged to help users in their service selection process. This paper reviews the recent approaches that have been introduced and used for cloud service brokerage and discusses their challenges accordingly. We propose a set of attributes for a CSB to be considered effective. Different CSBs’ approaches are classified as either single service or multiple service models. The CSBs are then assessed, analyzed, and compared with respect to the proposed set of attributes. Based on our studies, CSBs with multiple service models that support more of the proposed effective CSB attributes have wider application in cloud computing environments.

TL;DR: In this article, an attempt has been made for analyzing the service provisioning techniques from different perspectives, including various techniques and methodologies, QoS parameter considered, context awareness, etc.
Abstract: Cloud Computing is all about delivering services over the Internet. It has some technical, business and economical aspects. The complexity of service provisioning has increased significantly with the increasing number of cloud services and their providers. This creates a complex situation and as a result the service provisioning techniques face hurdles. The challenge of service provisioning is to properly offer services by adjusting the complexities efficiently. There are significant works to solve the problem in different manners. But still there are some gaps that are to be noticed and bridged for future advancement of cloud technology research. In this paper an attempt has been made for analyzing the service provisioning techniques from different perspectives. The said perspectives are various techniques and methodologies, QoS parameter considered, context awareness, etc. Moreover, the role of a broker in this context is also addressed. The overall motivation is to identify the open challenges, that may provide a future research direction in context of service provisioning.

TL;DR: A novel approach is proposed for providing insurance coverage for such root events by limiting insurance provisions to the users with the highest priority, and a criterion is presented for priority assignment to users, and an algorithm is proposed to provide insurance according to this priority.
Abstract: Service-level agreement (SLA) violations may lead to losses and user dissatisfaction. Despite the fact that a service guarantee can increase the satisfaction level of users, indemnities may not be commensurate with the importance of a service to a user. While predefined penalties may be insufficient to compensate for the losses of one user, another user may not suffer loss from the SLA violation. With an insurance plan, an insurer can reach an agreement with users on the premium and loss coverage volume; insurance can therefore be considered a solution for providing indemnity which is appropriate to the importance of service. An insurer cannot protect users against these losses, which are caused by a single root event, in the same way as it protects them against the losses caused by independent events. In this paper, a novel approach is proposed for providing insurance coverage for such root events by limiting insurance provisions to the users with the highest priority. A criterion is presented for priority assignment to users, and an algorithm is then proposed for providing insurance according to this priority. A game-theoretic analysis is also provided to assess acceptability of the outcome of the proposed algorithm to rational users and insurers. The results of numerical experiments demonstrate the usefulness of the proposed approach for improving the utility of the service.

TL;DR: Based upon the analysis of the applicable legal theories, recommended approaches for businesses to address cloud computing risks are presented.
Abstract: Businesses currently use cloud-computing services with the uncertainty of jurisdiction, should legal action be initiated. Jurisdiction is the authority of a court to hear and decide a specific legal action. While standards, treaties and case law are developing worldwide, there currently is no simple test to determine jurisdiction for internet activities in the United States (US) or internationally, necessitating businesses to take the initiative to address cloud computing jurisdiction risk. Based upon our analysis of the applicable legal theories, we present recommended approaches for businesses to address cloud computing risks.

TL;DR: A novel combinatorial auction (CA)-based cloud market (CACM) model that enables a DC platform in CPs and a promising multi-objective (MO) optimization model for partner selection using individual information and past collaborative relationship information, which is seldom considered are proposed.
Abstract: Currently, interoperability and scalability are two major challenging issues for cloud computing. Forming a dynamic collaboration (DC) platform among cloud providers (CPs) can help to better address these issues. A DC platform can facilitate expense reduction, avoiding adverse business impacts and offering collaborative or portable cloud services to consumers. However, there are two major challenges involved in this undertaking; one is to find an appropriate market model to enable a DC platform, and the other one is to minimize conflicts among CPs that may occur in a market-oriented DC platform. In this paper, we present a novel combinatorial auction (CA)-based cloud market (CACM) model that enables a DC platform in CPs. To minimize conflicts among CPs, a new auction policy is proposed that allows a CP to dynamically collaborate with suitable partner CPs to form groups and publishes their group bids as a single bid to compete in the auction. However, identifying a suitable combination of CP partners to form the group and reduce conflicts is a NP-hard problem. Hence, we propose a promising multi-objective (MO) optimization model for partner selection using individual information and past collaborative relationship information, which is seldom considered. A multi-objective genetic algorithm (MOGA) called MOGA-IC is proposed to solve the MO optimization problem. This algorithm is developed using two popular MOGAs, the non-dominated sorting genetic algorithm (NSGA-II) and the strength pareto evolutionary genetic algorithm (SPEA2). The experimental results show that MOGA-IC with NSGA-II outperformed the MOGA-IC with SPEA2 in identifying useful pareto-optimal solution sets. Other simulation experiments were conducted to verify the effectiveness of the MOGA-IC in terms of satisfactory partner selection and conflict minimization in the CACM model. In addition, the performance of the CACM model was compared to the existing CA model in terms of economic efficiency.

TL;DR: This paper seeks to inform the potential cloud adopter, not only of the perceived great technological benefit, but to also bring to light the potential security, privacy, and related GRC issues which will need to be prioritized, managed, and mitigated before full implementation occurs.
Abstract: While acknowledging the many benefits that cloud computing solutions bring to the world, it is important to note that recent research and studies of these technologies have identified a myriad of potential governance, risk, and compliance (GRC) issues. While industry clearly acknowledges their existence and seeks to them as much as possible, timing-wise it is still well before the legal framework has been put in place to adequately protect and adequately respond to these new and differing global challenges. This paper seeks to inform the potential cloud adopter, not only of the perceived great technological benefit, but to also bring to light the potential security, privacy, and related GRC issues which will need to be prioritized, managed, and mitigated before full implementation occurs.
