Cloud Computing is the next generation Architecture of the most IT enterprise. It made possible, the application to run without the burden of local hardware and software. So, resource allocation is key issue in cloud computing.For better resource allocation cloud service providers use lease managers. Lease managers depend on their default scheduling algorithms and their efficiency of granting and revoking leases is dependent on efficiency of scheduler they have. Haizea, a lease manager written in python, provides three types of leases: Immediate, Best Effort (BE) and Advance Reservation (AR). AR leases are most privileged leases with "AR-preempts everything" policy, since they can preempt & suspend other BE leases when demanded. But BE or Immediate can't preempt other BE or Immediate. BE lease have to wait in queue. This work proposes priority based resource allocation algorithm to solve these problem. Experimental results of the proposed algorithm successfully demonstrate that we can get less waiting time for BE leases than default algorithm.
