Previous issue date: 2015-03-28 / Nowadays cloud computing is considered a new concept for the provision of computational infrastructure. In this environment, clients can access and use software, platform or infrastructure as a service to reduce their costs, compared to the traditional values of datacenter model. To make this feasible, customers are charged by the use of computer resources by means of a charging model. These models determine how the use of any product or service will be paid by a client to a service provider. However, the definition of a charging model involves the execution of a series of processes so that is possible to identify the best parameters of the model for each provider. Therefore, it is necessary to clearly define the type of service that the provider adopts and the products you want to offer to the market. Moreover, it is necessary to verify the sales strategies adopted by the provider and the cost of operation. These difficulties were also found by PUCRS High Performance Laboratory (LAD-PUCRS). To facilitate this process, this paper presents a methodology to define and optimize charging models for providers of cloud computing. The method was applied in the LAD, which resulted in several improvements to the charging models used by the laboratory. Furthermore, the application of the methodology in this case study was evaluated and contributed to its improvement. / Atualmente, as nuvens computacionais s?o consideradas um novo conceito para o fornecimento de infraestrutura computacional. Neste ambiente, os clientes acessam e utili-zam software, plataforma ou infraestrutura como servi?os, sendo cobrados por seu uso. H? dificuldades entre os provedores em definir um modelo de cobran?a para esse ambiente por envolver a execu??o de uma s?rie de processos na identifica??o dos melhores par?-metros, considerando requisitos espec?ficos dos modelos de servi?os, da infraestrutura dis-pon?vel, dos produtos ofertados e dos clientes, e tamb?m, das estrat?gias de venda e do custo de opera??o por parte do provedor. Uma metodologia para defini??o de modelos de cobran?a foi elaborada em fun??o do problema descrito mediante a revis?o da literatura e de pr?ticas reconhecidas de cobran?a. Foram constru?dos oito formul?rios, abarcando os processos da metodologia e submetidos aos respons?veis pelo Laborat?rio de Alto Desem-penho da PUCRS, conforme os procedimentos de estudo de caso ?nico. Pela metodologia s?o sugeridos novos par?metros para os modelos de cobran?a bem como indica??o de um novo produto: armazenamento al?m, das j? existentes, VM?s 24x7 e cluster. A metodologia aplicada refere-se a um caso ?nico, por?m, permite seu uso extensivo a outros casos, in-clusive, para sua valida??o.
