Approaches to improve the resources management in the simulator CloudSim

Abstract

In Cloud Computing, service availability and performance are two significant aspects to be dealt with. These two aspects can deteriorate or even stopping the services of Cloud Computing, if they are not taken into account. Users see that cloud computing delivers elastic computing services to users on the basis of their needs. This paper aims at improving operation of service of the Cloud Computing environment. Cloud service must be available some is the situations and powerful being by a response time reduced at a user's request. To meet this aim, we propose, in this paper, two approaches which aim at returning a better availability of Datacenters without deteriorating the performances for the answers of the users. The first uses the principle of the messages of availability and the second uses the principle of reservation in advance. © 2010 Springer-Verlag Berlin Heidelberg.
