Priority based Modified Throttled Algorithm in Cloud Computing

Abstract

In Cloud Computing environment, Load Balancing is an important aspect which divides task between a numbers of virtual machines (VMs). It ensures no VM would get overloaded or sit idle and the end user would get service faster. We have proposed an algorithm, which adds a new feature like priority basis service allocation of each user request. Determining the priority of a request, the task allocated to a Virtual Machines. A Switching queue has proposed to hold the request which has been removed temporarily from the V.M. due to the arrival of higher priority request. The waiting request resumed the execution after completion of the of higher priority task. We have proposed a Priority based Modified Throttled Algorithm (PMTA) which has improved average execution time in comparison to the existing load balancing algorithm such as Throttled and Round Robin.
