Multi level fault tolerance in cloud environment
K Devi, D. Paulraj · 2017
Cloud computing provides different kind of services to users. With the increased demand of services, chances of fault are also high. To reduce the impact of the fault, many fault tolerance techniques have been designed and proposed. This paper proposed a multilevel fault tolerance system to tolerate the faults in real time cloud environment by providing higher reliability and availability. In the first level, reliable virtual machines are identified using reliability assessment algorithm and in the second level availability of data is achieved through replication mechanism. Thus the system provides an efficient fault tolerant mechanism in multi-level fashion.
