Abstract :
Cloud computing is an utility computing paradigm that allows users to flexibly acquire virtualized computing resources in a pay-as-you-go model. To realize the benefits of using cloud, users need to first select the suitable cloud services that can satisfy their applications´ functional and non-functional requirements. However, this is a difficult task due to large number of available services, users´ unclear requirements, and performance variations in cloud. In this paper, we propose a system that evaluates trust of clouds according to users´ fuzzy Quality of Service (QoS) requirements and services´ dynamic performances to facilitate service selection. We demonstrate the effectiveness and efficiency of our system through simulations and case studies.
