Cloud computing in educational applications methods of virtual desktops deployment

Abstract

Task scheduling is one of the main parts of Cloud Computing (CC). We understand this process as mapping users tasks to appropriate resources to execute. Since we use virtual machines (VM) to hide physical resources form user the critical problem is how to schedule this machines (sub tasks) in given resources (ie. host machines). Tasks scheduling algorithms for CC systems are discussed in literature [2][4][5]. The most authors use mathematical model without consideration of many problems with desktop virtualization. In this paper we consider a new model for tasks scheduling of VM deployment for business and educational purposes. We also introduce genetic algorithm [1] for task scheduling in CC. © 2012 Springer-Verlag.
