An Intelligent Cloud Broker with Service Ranking Algorithm for Validation and Verification of Cloud Services in Multi-cloud Environment

Abstract

Abstract Cloud computing offers a widespread variety of services for the users. In multi-cloud environment, the service centric features are introduced to assist the cloud users from the multiple endpoints. In order to enhance the service availability, cloud brokerage is introduced into the multi-cloud environment that outperforms the effective utilization of required services. The primary objective of a cloud broker is to ensure about the services and its outcomes while offering them to a customer. The role of a traditional broker has the restrictions such as measuring the service trust, validity, and the future enhancement of the considered cloud services from the multi-cloud environment. Hence, the need for the intelligence feature is highly solicited in the cloud broker while working in a multi-cloud environment. The proposed intelligent cloud broker performs the validation and verification of service trust details by analysing the service trust factors such as service response time, sustainability, suitability, accuracy, transparency, interoperability, availability, reliability, stability, cost, throughput, efficiency, scalability of the cloud services. The customer’s feedback is taken into consideration for measuring the service trust factors before the service recommendation. In this proposed model, the Service Ranking (SR) values are calculated for the available cloud services. Additionally, the proposed model considers the newly arrived services during cloud services validation process by mapping its services with the available cloud services from the Service Collection Repository (SCR). Hence, this proposed model outperforms well in the process of recommending services to the cloud users.
