A priority based job scheduling algorithm using IBA and EASY algorithm for cloud metaschedular

Job scheduling (JS) is one of the most important issues in a Cloud system. The objective of job schedulers in cloud computing is to meet users' requirements and optimize the utilization of cloud resources. To achieve better QoS with high resource utilization in a cloud environment, an improved backfill algorithm (IBA) using balanced spiral (BS) method can be used. Results show that IBA minimizes resource idleness up to a great extent. However, IBA does not provide support for handling job priority and QoS. We need an algorithm to maximize the resource utilization while considering priority.
