QoS based trust management model for Cloud IaaS

Trust Models are used to enhance secure and reliable scheduling in Distributed, Grid and Cloud environment. Trust models that are being proposed or implemented in Distributed and Grid environment, does not fully fit in cloud computing environment. Since the parameters that have being taken into consideration in these trust models, does not fit in the cloud Infrastructure As A Service, a suitable trust model is proposed based on the existing model that is suitable for trust value management for the cloud IaaS parameters. Based on the above achieved trust values, a scheduling is done for better allocation of resources and further enhance the QOS of services been provided to the users. In this paper, an approach for managing trust in Cloud IaaS is proposed.
