Cloud computing is currently emerging as an ever-changing, growing paradigm that models “everything-as-a-service.” Virtualised physical resources, infrastructure, and applications are supplied by service provisioning in the cloud. The evolution in the adoption of cloud computing is driven by clear and distinct promising features for both cloud users and cloud providers. However, the increasing number of cloud providers and the variety of service offerings have made it difficult for the customers to choose the best services. By employing successful service provisioning, the essential services required by customers, such as agility and availability, pricing, security and trust, and user metrics can be guaranteed by service provisioning. Hence, continuous service provisioning that satisfies the user requirements is a mandatory feature for the cloud user and vitally important in cloud computing service offerings. Therefore, we aim to review the state-of-the-art service provisioning objectives, essential services, topologies, user requirements, necessary metrics, and pricing mechanisms. We synthesize and summarize different provision techniques, approaches, and models through a comprehensive literature review. A thematic taxonomy of cloud service provisioning is presented after the systematic review. Finally, future research directions and open research issues are identified.

Cloud computing is comprised of major demand from the every group of organization because of easy availability and cost effectiveness. The responsibilities of cloud service providers will become increasing more due to the great progression in every cloud computing deployment model (public, private and hybrid) and service models (SaaS, PaaS and IaaS). In this perspective, cloud computing faces multiple challenges, especially in cloud computing security at all levels (e.g., host, network, application and data levels). Authentication is the constantly the biggest concerned for IT industries to adopt cloud computing environment. The availability, performance, key logger attack, malicious insiders, outsider attacks and service disruptions explore (service hijacking) issues are the key research challenges in the cloud computing authentication level. In this aspect, traditional user name and password is not enough as a single factor (first factor). This paper has proposed a secure cloud computing framework which uses first factor as a crypt user name and password with the ATM pin as a second factor called M-pin. The proposed work focuses on a solution to the threats that are the major issues in the cloud adoption.

Provisioning Strategies

Cloud computing has become the dominant provisioning model for IT services. This research adopts the provider's perspective to explore profitable service provisioning strategies: industrialization and standardization vs. service individualization. Based on a survey and expert interviews among cloud service providers, the authors identify that focusing on service individualization does not pay off for cloud service providers. Instead, cloud service providers should adopt industrialization and automation. Even more, they find that exploitation mechanisms of organizational learning significantly improve the cloud service profitability.

Improve Service Quality

Since many Internet enterprises employ the computing resources provided by Cloud Service Provider (CSP), how to dynamically adjust the number of rented servers and improve service quality becomes a crucial subject. A lot of efforts have been made to achieve intelligent energy saving capacity adjustment but scarcely any of them takes the security issue of cloud data into account. In this paper, we focus on the cloud storage security in the cloud computing capacity scaling. We design the security part of the whole model based on the idea of Proofs of Retrievability (POR). In the scaling part of the model, we determine the scaling strategy according to email server instances CPU utilization. With simulation and performance evaluation, we conclude that the designed model is able to enable verifier to check the integrity of the information in the cloud storage and maintain satisfied response time target within Service Level Agreement (SLA).

Proof Of Retrievability

Cloud computing and cloud data storage have become important applications on the Internet. An important trend in cloud computing and cloud data storage is group collaboration since it is a great inducement for an entity to use a cloud service, especially for an international enterprise. In this paper we propose a cloud data storage scheme with some protocols to support group collaboration. A group of users can operate on a set of data collaboratively with dynamic data update supported. Every member of the group can access, update and verify the data independently. The verification can also be authorized to a third-party auditor for convenience.

Health Cloud

Although the electronic health (e-health) cloud computing system is a promising innovation, its adoption in the healthcare industry has been slow. This study investigated the adoption of e-health cloud computing systems in the healthcare industry and considered security functions, management, cloud service delivery, and cloud software for e-health cloud computing systems. Although numerous studies have determined factors affecting e-health cloud computing systems, few comprehensive reviews of factors and their relations have been conducted. Therefore, this study investigated the relations between the factors affecting e-health cloud computing systems by using a multiple criteria decision-making technique, in which decision-making trial and evaluation laboratory (DEMATEL), DANP (DEMATEL-based Analytic Network Process), and modified VIKOR (VlseKriterijumska Optimizacija I Kompromisno Resenje) approaches were combined. The intended level of adoption of an e-health cloud computing system could be determined by using the proposed approach. The results of a case study performed on the Taiwanese healthcare industry indicated that the cloud management function must be primarily enhanced and that cost effectiveness is the most significant factor in the adoption of e-health cloud computing. This result is valuable for allocating resources to decrease performance gaps in the Taiwanese healthcare industry.

Cloud computing is associate inclusive new approach on however computing services square measure made and utilized. Cloud computing is associate accomplishment of assorted styles of services that has attracted several users in today’s state of affairs. The foremost enticing service of cloud computing is information outsourcing, because of this the information homeowners will host any size of information on the cloud server and users will access the information from cloud server once needed. A dynamic outsourced auditing theme that cannot solely defend against any dishonest entity and collision, however conjointly support verifiable dynamic updates to outsourced information. The new epitome of information outsourcing conjointly faces the new security challenges. However, users might not totally trust the cloud service suppliers (CSPs) as a result of typically they may be dishonest. It's tough to work out whether or not the CSPs meet the customer’s expectations for information security. Therefore, to with success maintain the integrity of cloud information, several auditing schemes are projected. Some existing integrity ways will solely serve for statically archived information and a few auditing techniques is used for the dynamically updated information. The analyzed numerous existing information integrity auditing schemes together with their consequences.
