Abstract(s)
O conceito de Cloud Computing tem sido amplamente discutido sendo uma vertente desta abordagem a redução dos custos. São diversos os prestadores de serviços de Cloud existentes no mercado e diversificados os modelos de serviços que estes disponibilizam através da internet. É objetivo deste artigo apresentar uma breve caracterização do estado da arte no que se refere a esta temática bem como suportar o seu conteúdo num estudo efetuado numa Organização de média dimensão. Foram abordadas duas perspectivas nesse estudo: utilização de serviços de gestão e arquivo do correio eletrónico em infraestrutura do fornecedor (Public Cloud), e virtualização de ambiente de trabalho desktop, em servidores de data-center interno (Private Cloud). Foi possível concluir que cada fornecedor adequa os modelos de negócio à sua especialidade, originando um mercado heterogéneo e de difícil análise comparativa dos serviços disponibilizados. Considera-se que será premente a conceção de protótipos que avaliem em contexto organizacional a viabilidade das soluções a implementar.
The concept of Cloud Computing has been discussed largely by cost reduction. There are several Cloud providers in the market with diversified models of services accessed over the internet. The purpose of this paper is to present the state of the art with regard to this issue and frame a study conducted in a medium-sized organization. Two perspectives were addressed in this study: use of electronic mail management services in the provider's infrastructure (Public Cloud), and desktop virtualization desktop in internal datacenter (Private Cloud). It was concluded that vendors are making the business models according to their specialty, resulting in a very heterogeneous market and a difficult benchmarking analysis of the services offered, pointing to the need for prototyping tested in the field to assess the feasibility of the solutions.
