- Abstract
Nowadays, the cloud computing appears as a magic solution for a lot of companies and scientific problems to have extendable resources with a suitable budget. The increasing of the utilization of cloud computing in different fields creates challenge in the reliability and availability of the system. In this paper, a middle layer is proposed to increase the reliability. This layer places between the application layer and the virtualization layer in cloud system. It aims to handles the failure of the nodes. This layer monitors the system resources and periodically updates the status of all the virtual machine functionality. Based on these statuses, when the failure is occurred, the appropriate virtual machine will be selected to handle object failure. Moreover, the failure is handled in two cases, firstly, when the failure occurred in one of the running virtual machine, secondly, when the failure is occurred at the virtual machine management.
