Abstract. As a new technology in IT industry, cloud computing has been much focused by both academia and industry. And many topics in cloud computing are under study. However, as one of the most important issue, billing and pricing has been not so much concerned. In this paper, we propose a novel pay-peruse billing model that can be used for the applications in cloud computing. Built based on leasing instances, the model is put forward according to the analysis of the real applications in the cloud computing environment. That is, with the model, the users will be charged totally by the amount of the resources they have used. Simulation results show that the model is correct and feasible.
Cloud computing is a new computing model. The resource monitoring tools are immature compared to traditional distributed computing and grid computing. In order to better monitor the virtual resource in cloud computing, a periodically and event-driven push (PEP) monitoring model is proposed. Taking advantage of the push and event-driven mechanism, the model can provide comparatively adequate information about usage and status of the resources. It can simplify the communication between Master and Work Nodes without missing the important issues happened during the push interval. Besides, we develop "mon" to make up for the deficiency of Libvirt in monitoring of virtual CPU and memory.
