Aplicação do método de análise hierárquica na tomada de decisão para adoção de computação em nuvem: um estudo de caso na federação das indústrias do RN

摘要

The progresses of the Internet and telecommunications have been changing theconcepts of Information Technology IT, especially with regard to outsourcing services,where organizations seek cost-cutting and a better focus on the business. Along with thedevelopment of that outsourcing, a new model named Cloud Computing (CC) evolved. Itproposes to migrate to the Internet both data processing and information storing. Amongthe key points of Cloud Computing are included cost-cutting, benefits, risks and the ITparadigms changes. Nonetheless, the adoption of that model brings forth somedifficulties to decision-making, by IT managers, mainly with regard to which solutionsmay go to the cloud, and which service providers are more appropriate to theOrganization s reality. The research has as its overall aim to apply the AHP Method(Analytic Hierarchic Process) to decision-making in Cloud Computing. There to, theutilized methodology was the exploratory kind and a study of case applied to anationwide organization (Federation of Industries of RN). The data collection wasperformed through two structured questionnaires answered electronically by ITtechnicians, and the company s Board of Directors. The analysis of the data was carriedout in a qualitative and comparative way, and we utilized the software to AHP methodcalled Web-Hipre. The results we obtained found the importance of applying the AHPmethod in decision-making towards the adoption of Cloud Computing, mainly becauseon the occasion the research was carried out the studied company already showedinterest and necessity in adopting CC, considering the internal problems withinfrastructure and availability of information that the company faces nowadays. Theorganization sought to adopt CC, however, it had doubt regarding the cloud model andwhich service provider would better meet their real necessities. The application of theAHP, then, worked as a guiding tool to the choice of the best alternative, which pointsout the Hybrid Cloud as the ideal choice to start off in Cloud Computing. Considering thefollowing aspects: the layer of Infrastructure as a Service IaaS (Processing andStorage) must stay partly on the Public Cloud and partly in the Private Cloud; the layerof Platform as a Service PaaS (Software Developing and Testing) had preference forthe Private Cloud, and the layer of Software as a Service - SaaS (Emails/Applications)divided into emails to the Public Cloud and applications to the Private Cloud. Theresearch also identified the important factors to hiring a Cloud Computing provider
