A review paper on Fault Tolerance in Cloud Computing

Cloud computing demand is increasing due to which it is important to provide correct services in the presence of faults also. The Resources in cloud computing can be dynamically scaled that too in a cost effective manner. Fault Tolerance is the process of finding faults and failures in a system. If a fault occurs or there is a hardware failure or software failure then also the system should work properly. Failures should be managed in a effective way for reliable Cloud Computing. It will also ensure availability and robustness. This paper aims to provide a better understanding of fault tolerance techniques which are used for managing faults in cloud. It also deals with some existing Fault tolerance model.
