Rate aware Meta task Scheduling Algorithm for multi cloud computing (RAMTSA)

Abstract

Multicloud attains a larger momentum by gratifying the needs of the more number of heterogeneous cloud users. The inherent parts that are used in the multicloud systems are analogous, scheduling and rescheduling. In the analogous aspect, requests from the first user are given more priority and tasks are delegated to the virtual machines. In the scheduling phase, round robin based mechanism is used to accomplish the tasks in all the clouds. Rescheduling is a mechanism of shifting the executed tasks of one cloud to the another cloud. The expenditure of exceution of the tasks around 15 % are merely reduced in the rescheduling phase. This article is merely focused to dwindle the exceution costs of the VMs in the clouds. The denouement of the propounded algorithm manifests better when it is compared with conventional min-min algorithm.
