Managing Cloud Data Centers with Three-State Server Model Under Job Abandonment Phenomenon

摘要

In fact, to improve the quality of system service, for user job requests, which already have waited for a long time in queues of a busy cluster, cloud vendors often migrate the jobs to other available clusters. This strategy brings about the occurrence of job abandonment phenomenon in data centers, which disturbs the server management mechanisms in the manner of decreasing effectiveness control, increasing energy consumptions, and so on. In this paper, based on the three-state model proposed in previous works, we develop a novel model and its management strategy for cloud data centers using a finite queue. Our proposed model is tested in a simulated cloud environment using CloudSim. The achieved outcomes show that our three-state server model for data centers operates well under the job abandonment phenomenon.
