“…Trust in cloud computing environment based on the selected cloud deployment models in which the applications are delegated and outsourced to the control of the owner. Trust has required an efficient and effective security policy in the traditional architecture that addressed the functional constraints and flows between them [35], [36]. External systems access the constraints that attack the programs which effect the access or control on the customer data.…”

Abstract-Cloud computing exhibits a remarkable potential to offer cost-effective and more flexible services on-demand to the customers over the network. It dynamically increases the capabilities of the organization without training new people, investment in new infrastructure or licensing new software. Cloud computing has grown dramatically in the last few years due to the scalability of resources and appear as a fast-growing segment of the IT industry. The dynamic and scalable nature of cloud computing creates security challenges in their management by examining policy failure or malicious activity. In this paper, we examine the detailed design of cloud computing architecture in which deployment models, service models, cloud components, and cloud security are explored. Furthermore, this study identifies the security challenges in cloud computing during the transfer of data into the cloud and provides a viable solution to address the potential threats. The task of Trusted Third Party (TTP) is introducing that ensure the sufficient security characteristics in the cloud computing. The security solution using the cryptography is specifically as the Public Key Infrastructure (PKI) that operates with Single-Sign-On (SSO) and Lightweight Directory Access Protocol (LDAP) which ensure the integrity, confidentiality, availability, and authenticity involved in communications and data.

“…Weng et al [40] empregam o conceito de confiança na troca de arquivos confidenciais e destacam que o relacionamento de confiança entre os parceiros é a base para a colaboração. Karaoglanoglou e Karatza [41] apresentam um mecanismo em que o processo de direcionamento de requisições a provedores confiáveis é feito com base nos valores globais de confiança. Em Nogoorani e Jalili [42] é proposto um framework para controle de acesso a ambientes de Grid Computing, no qual a validação da confiança e o gerenciamento de risco são adicionados aos serviços básicos de controle de acesso disponíveis em uma Grid.…”

AsOrganizaçõesVirtuaisrepresentamumaproeminenteformadecola- boração na qual um conjunto de empresas compartilham habilidades, competências e riscos para atender um objetivo em comum. Algumas preocupações surgem durante a colaboração, como, por exemplo, questões relativas a confiança, reputação e o uso de recursos tecnológicos. A confiança e a reputação nas OVs visam minimizar o risco ao lidar com entidades desconhecidas. Já o uso de recursos tecnológicos, como por exemplo computação em nuvem, fornece suporte a oportunidade de colaboração po- rém apresenta alguns problemas relacionados a autenticação, segurança, privacidade e confiança. Portanto, este artigo apresenta uma revisão sistemática cujo objetivo é veri- ficar as abordagens que estão sendo realizadas no contexto das Organizações Virtuais e que estejam relacionadas com pelo menos um dos conceitos de confiança, reputação ou computação em nuvem. Para tal, a busca junto a literatura especializada resultou em 75 artigos, sendo selecionadas 24 deles para análise. Os critérios utilizados para a seleção foram os artigos relevantes nos últimos 5 anos, completos, no idioma inglês e que relacionassem Organização Virtual com pelo menos um dos conceitos de confi- ança, reputação e computação em nuvem. Por conseguinte, identificou-se como cada conceito é abordado e verificou-se que um mesmo conceito apresenta-se de diferentes formas e nenhum dos trabalhos buscou apresentar a integração desses conceitos.

“…Currently most of these existing methods focused on the optimization of allocating physical resources to their associated virtual resources and migrating virtual machines to achieve load balance and increase resource utilization. These methods require the suspension of the cloud computing applications due to the mandatory shutdown of the associated virtual machines [73][74][75][76][77][78][79][80][81]. The protection of information privacy under the development of cloud computing technology is the latter situation [82][83][84][85][86][87][88][89].…”

The manufacturing industry is undergoing a major transformation enabled by IT and related smart technologies. The main thrust of Cloud computing is to provide on-demand computing services with high reliability, scalability and availability in a distributed environment. This paper summarizes our taxonomy of the CC review direction. The goals of this taxonomy were (i) clarify the needs and the directions of the use of the CC, (ii) define the academic and practical issues involved in CC , (iii) learn the state of the directions on methodologies of the CC , (iv) identify future research directions, which benefit the short and long terms. The taxonomy has concluded that (i) CC is advantageous in dealing with changes and uncertainties in the every-changing environment. (ii)It has been found that few existing CC can achieve the objective of security. (iii) The obstacles of the development of CC include the difficulties to identify and generalize the requirement of CC security, the lake of effective technologies that can be used to support the clouding use, and no international origination that serves for standardizing the modular components for cloud computing processes. In this paper, we use the IVSL(The Iraq Virtual Science Library) to select the free, full-text access to papers from major publishers as well as a large collection of on-line educational materials.
