42 Research on Building Fault Detection Solution for IaaS Cloud Computing Based on Fuzzy Logic Algorithm

The availability is one of the most vital prerequisite issues in providing IaaS Cloud Computing services. It means any fault must be identified and reacted reasonably in order to ensure quality of service [3]. To achieve this requirement, fault tolerance system in IaaS has to balance accuracy in fault detection with reaction rate. In this paper, we present a new approach based on fuzzy logic to detect faults happening in IaaS accurately and flexibly.
