Dynamic resource provisioning in Cloud Computing environment using priority based virtual machine´s

Today, Cloud Computing become one of the most promising an emerging technology which will has a significant impact on IT Infrastructure. Still, Cloud Computing is infancy. In the current cloud computing environment there is numerous of application, consist of millions of module, these application serve from large quantity of users and user request becomes dynamic. So there must be provision that all resources are dynamically made available to satisfy the needs of requesting a user in a situation where the resource contention fierce is occurs. In this paper, we propose scheduling heuristic to allocate resource and schedule request for cloud system. An aim of proposed scheduling heuristic is to schedule request on Virtual Machine (VM) based on agreed Service Level Agreements (SLA) and creating new VM on physical resources based on availabilities of resources which considered priority based VM allocation, Load Balancing and Preemption Mechanism. And the experimental results of proposed heuristic helps to optimize performance and at the same time reduce the possibilities of SLA violations.
