AFTTM: Agent-Based Fault Tolerance Trust Mechanism in Cloud Environment

Cloud Computing has now successfully emerged as an integral trend in Information Technology market. It is internet-based concept of virtualization. Many failures can occur in 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 which can deploy the checkpoint module so that faults can be detected timely and shall 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 actually is an intelligent and reliable agent that helps in detecting the malicious faults on time. The proposed framework considers throughout overheads, checkpoints overheads, monetary costs overheads and availability overheads in its performance validation. The proposed framework has been compared with other two frameworks and has been identified that AFTTM outperforms several on-going techniques in fault tolerant techniques.
