T-broker A Trust-aware Service Brokering Scheme for Multiple Cloud Collaborative Services - 2015
Oriented by requirement of trust management in multiple cloud setting, this paper presents T-broker, a trust-aware service brokering theme for efficient matching cloud services (or resources) to satisfy numerous user requests. 1st, a trusted third party-primarily based service brokering architecture is proposed for multiple cloud environment, in which the T-broker acts as a middleware for cloud trust management and repair matching. Then, T-broker uses a hybrid and adaptive trust model to compute the general trust degree of service resources, in which trust is defined as a fusion evaluation result from adaptively combining the direct monitored proof with the social feedback of the service resources. A lot of importantly, T-broker uses the maximizing deviation method to compute the direct expertise based mostly on multiple key trusted attributes of service resources, that will overcome the restrictions of traditional trust schemes, in which the trusted attributes are weighted manually or subjectively. Finally, T-broker uses a light-weight feedback mechanism, which can effectively reduce networking risk and improve system potency. The experimental results show that, compared with the present approaches, our T-broker yields very sensible ends up in several typical cases, and the proposed system is sturdy to house various numbers of dynamic service behavior from multiple cloud sites.
