Cloud computing has now successfully emerged as an integral trend in the information technology market. It is an internet-based concept of virtualization. Many failures can occur in the computing environment that actually leads to non-availability and non-reliability upon service providers. To ensure this, a mechanism has been proposed in this paper that can deploy the checkpoint module so that faults can be detected quickly and be removed in due course of time so that reliable and fault free cloud services can be provided to consumers. In this, fault tolerance agent has been used, which is an intelligent and reliable agent that helps in detecting the malicious faults on time. The proposed framework considers throughout overheads, checkpoint overheads, monetary costs overheads, and availability overheads in its performance validation. The proposed framework has been compared with the other two frameworks, and it has been identified that AFTTM outperforms several on-going techniques in fault tolerant techniques.
