With the recent maturity of Cloud computing technology and the flexibility of the Cloud services, the offering of Cloud services has spread exponentially. Different Cloud service providers offer their services highlighting different features of their services. Because of the diversity of Cloud services and their highlighted features, the choice of the most suitable Cloud service is a complex problem for the Cloud users. Many Cloud users are unable to identify the Cloud services that best suit their needs and thus choose an unsuitable Cloud service, which results in financial loses as well as time delays. To this end, in this study, we propose an efficient three layered framework for evaluating and ranking IaaS, PaaS and SaaS Cloud services. We identified the functional and non-functional key performance indicators (KPIs) for Cloud services from 6 KPI classes. We classified these KPIs with respect to their types and criticality so that the Cloud user can easily choose according to his needs. The relative importance of the KPIs was determined using CRITIC method. We combined the KPIs values and their relative importance for an overall evaluation and ranking of the Cloud services using Vikor method. A case study is also presented for a step by step demonstration of the proposed method.

“…In the network many Quality-of-Service parameters are considered for evaluating behavioural trust value. In Cloud computing, service level agreement parameters are assumed to maintain the feedback and compute the feedback trust value of the cloud service provider [22]. Feedback proves the genuineness of participants.…”

The Psychology of Trust

Trust, defined as the willingness to accept risk and vulnerability based upon positive expectations of the intentions or behaviours of another. The qualities or behaviours of one person that create good expectations in another are referred to as trustworthiness. Because of its perceived link to cooperative behaviour, many social scientists regard trust as the backbone of effective social structures. With the advancement in technology, through these online social media people can explore various products, services and facilities. Through these networks the end users want to communicate are usually physically unknown with each other, the evaluation of their trustworthiness is mandatory. Mathematical methods and computational procedures do not easily define trust. Psychological and sociological factors can influence trust. End users are vulnerable to a variety of risks. The need to define trust is expanding as businesses try to establish effective marketing strategies through their social media activities, and as a result, they must obtain consumer trust. Game theory is a theoretical framework for analysing strategic interactions between two or more individuals, in the terminology of game theory, called players. Thus, a conceptual framework for trust evaluation can be designed using a game theory approach that can indicate the conditions under which trustworthy behaviour can be determined.

“…Using users' feedback and behaviour, authors in [11] proposed an Evidence Trust model to select the trusted Cloud Service Provider (CSP). The final assigned trust value is computed through cumulating feedback and behavioural trust and would determine the trustworthiness of a CSP.…”

With the recent increase demand for cloud services, handling clients' needs is getting increasingly challenging. Responding to all requesting clients with no exception could lead to security breaches, and since it is the provider's responsibility to secure not only the offered cloud services but also the data, it is important to ensure clients reliability. Although filtering clients in the cloud is not so common, it is required to assure cloud safety.In this paper, we made use of multi agent system interaction mechanisms to handle the cloud interactions for the providers' side, and of Particle Swarm Optimization to select the and determine the accurate trust weight and therefore to filtrate the clients by determining malicious and untrustworthy clients. The selection depends on previous knowledge and overall rating of trusted peers. The conducted experiments proves that the combination between MAS, PSO and trust outputs relevant results with different number of peers, the solution is able to converge to the best result after small number of iterations. To explore more space and scenarios, synthetic data was generated to improve the model's precision .
