RESUMO

This report presents and depicts the research carried out in order to find out recommendations that may possibly assist consumers of cloud computing services to deal with risks intrinsic to that architecture, so that consumers can be able to contract those kinds of services within an acceptable level of risk. The research comprised five phases to satisfy this main objective and also the secondary ones set up for it: review the literature related to cloud computing, choose and configure the research method, run the research method, find out the recommendations and make conclusions. The review of the literature consisted of an extensive bibliography research about cloud computing, putting emphasis on its definitions and reference models and on three other connected topics: barriers, benefits and risks. The choice of the research method encompassed the selection of the Delphi method seconded by another wide bibliography research, this time focused on the method itself, and was followed by the configuration of the Delphi method in order to get a script to be adopted to make properly use of the method in this research; to apply the Delphi method, it was chosen its \"ranking form\", that made possible, after five rounds and counting with the involvement of a group comprising academic people and information technology professionals, to establish rankings for barriers, benefits and risks, all related to cloud computing. Based on the ranking of risks, the recommendations destined to satisfy the research\ s main objective were thought up; in general, these recommendations can be viewed as indicatives of which potentials risks must be observed and treated in an upper attention level by institutions, organizations and information technology executives that intend to take their first steps toward cloud computing universe, as long as by those companies and people that, despite by now inserted in that architecture, want to or must review concepts and positions already took on. At last, conclusions and final considerations were written, both derived from the analysis of the results regarding barriers and benefits extracted from the Delphi panel. Above all, this study, as its major contribution, offers a realistic view on the subject of cloud computing and puts a list of useful and timely reflections and recommendations within reach of those who are effectively interested in them, by proper will or due to duties.
