Cloud Computing provides the reliable services to clients through data centers which contains servers, storage etc.The major constraint of the systems used in real time applications is that, they are prone to failure.The failure may be due to the following reasons: a) Failure to complete the task in prescribed time threshold value.b) Failure to achieve prescribed reliability value.To ensure reliability and availability of cloud technologies, methods to enhance fault tolerance needs to be developed and deployed.In the proposed work, Reliability Assessment Framework (RAF) has been developed to tolerate the faults of real time applications running on cloud infrastructure.The proposed RAF calculated the reliability of virtual nodes using adaptive fault tolerant method.Backward recovery technique has also been implemented to make the system fault tolerant and the calculated reliability value of virtual nodes help in replacing the failure nodes making the cloud platform more reliable and also enhanced the performance of cloud nodes.. Various parameters like Acceptance Computation, Minimum Reliability, Reliability Factor and System Reliability Level have been taken into consideration while implementing the framework.
