Three‐phase service level agreements and trust management model for monitoring and managing the services by trusted cloud broker

Abstract

Cloud computing is an environment where everything is provided as a service based on demand. It follows pay as per the used model in which the service consumer needs to pay for what they have consumed. Due to the increased dependence on digitalization, the number of consumers and providers tends to grow tremendously. The consumer who needs the service from the provider is not sure about the specified service outcome, and it is too hard for them to monitor and manage the service. Hence, a trusted third party called a trusted cloud broker (TCB) is introduced for managing the services. The service level agreements (SLA) management and reputation estimation framework is proposed, which includes three phases such as (i) SLA establishment between the three parties, (ii) violation detection by comparing the observed value of the TCB and (iii) the reputation and penalty estimation of the service. The novel TCB is created to monitor the deployed services, ensuring the achievement of SLA. The TCB observes the values and estimates the reputation value for each service. It is compared with the provider log-based reputation value and found that the proposed model provides a more precise reputation value for the service providers.

“…The cloud centers can provide more services and applications; the corresponding ones are available locally with just the network [2]. Thus, the user needs are increasing, while the user's equipment does not need to be upgraded immediately, but only through the services of the cloud the user can reach their needs, reducing the equipment investment and updates, and the services can be continuously upgraded [3][4][5]. Along with the development of computer technology, cloud computing technology has been developed, and the application of all aspects has been relatively mature.…”
