Abstract—Cloud computing is a provisioning of services in a timely, on-demand manner, to allow the scaling up and down of resources. Job scheduling is one of the major issues in the public cloud which concerns availability of resources in the datacenter. Data center need to achieve certain level of utilization of its nodes while maintaining level of responsiveness of parallel jobs. Existing scheduling schemes make use of backfilling strategies which pre-empt shortest jobs to execute when jobs at head of the queue have unavailable of resources. This results in starvation of larger jobs, reduced throughput and underutilization of resources. In this paper, job scheduling based on virtual abstraction scheme is proposed for efficient scheduling of jobs in k- cloud data center with multiple computing capacities which solves large-scale static scheduling problem in cloud.
