“…For instance, Fuzzy AHP (FAHP) [20] is an extended algorithm AHP and modified VIKOR [21] is an extension of the VIKOR algorithm. Similarly, Rai et al [22] have used TOPSIS and VIKOR to select the best cloud service. Apart from these, many extensions have been made by targetting various applications.…”

Cloud computing is growing tremendously for its on-demand services, a massive pool of distributed resources, rapid provisioning of resources, and many more. It empowers many organizations/customers to build on-demand applications without investing large capital in creating hardware infrastructure. These organizations encounter numerous challenges towards obtaining full-pledged services from the cloud service providers (CSPs). One such challenge is identifying and deciding upon a suitable CSP that can fulfill the quality of service (QoS) requirements of these organizations. Moreover, the services offered by the CSPs are interrelated and beneficial, and non-beneficial. As a result, it makes it difficult for organizations to suitably evaluate the services rendered by the CSPs. Therefore, multi-attribute decision-making (MADM) algorithms are applied in the literature to overcome the above challenge of uncertainty. In this paper, we survey applications of such algorithms from the perspective of cloud computing. The survey covers both traditional and recent algorithms with their objectives, processes, pros, cons, and implementations. We also present the upcoming challenges and open issues, followed by the performance metrics and tools for their possible implementations. Finally, we conclude by summarizing the survey with some notable remarks.

Information storage and access in multi-cloud environments have become quite prevalent. In this paper, a multi-cloud framework is presented that secures users’ data. The primary goal of this framework is to secure users’ data from untrusted Cloud Service Providers (CSPs). They can collude with other malicious users and can hand over users’ data to these malicious users for their beneficial interests. In order to achieve this goal, the data are split into parts, and then each part is encrypted and uploaded to a different cloud. Therefore, client-side cryptography is used in this framework. For encrypting users’ data, the BDNA encryption technique is used. This framework presents a hybrid cryptographic approach that uses Identity-based Broadcast Encryption (IBBE) for managing the keys of the symmetric key algorithm (BDNA) by encrypting them with the particular version of IBBE. The work presented in this research paper is the first practical implementation of IBBE for securing encryption keys. Earlier, IBBE was only used for securely broadcasting data across many users over a network. The security of this hybrid scheme was proved through Indistinguishable Chosen-Ciphertext Attacks. This double encryption process makes the framework secure against all insiders and malicious users’ attacks. The proposed framework was implemented as a web application, and real-time storage clouds were used for storing the data. The workflow of the proposed framework is presented through screenshots of different working modules.
