Fault Tolerance in Cloud Computing
S. Sudha Lakshmi, Systems Operator · 2013
Cloud computing may be defined as management and provision of resources, software, application and information as services over the cloud or internet on demand. Most of the real time systems are also safety critical and should be highly reliable. So there is an increased requirement for fault tolerance to achieve reliability for the real time computing on cloud infrastructure. In this paper, a fault tolerance in real time cloud computing Environment is proposed. In the proposed model, the system tolerates the faults and makes the decision on the basis of reliability of the processing nodes, i.e. virtualmachines.The proposed technique is based on the execution of design diverse variants on multiple virtual machines, and assigning reliability to the results produced by variants. The system provides both the forward and backward recovery mechanism.
