Abstract: In cloud computing, the availability and the performance of the services are two significant aspects to be dealt with. These two aspects can deteriorate to see 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 based on their needs. This paper aims at improving operation of cloud service of the cloud computing environment. Cloud services must be available in every situation possible and improving performance in this environment. To meet this aim, we propose, in this paper, two approaches which aim at returning a better availability of datacenters without deteriorated 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.
Keywords: cloud computing; CloudSim; broker; messages of availability; reservation in advance; resource management; cloud services.
