Método de análise para adoção de computação em nuvem: estudo de casos em organizações de grande porte.

Abstract

Cloud Computing (CC) is potentially able to change a major part of Information Technology (IT) industry. Its evolution over the past few years is certainly one of the greatest advancements in the history of computing. Cloud Computing has been gaining ground as a successful model as it promises economic savings, easiness of use and greater flexibility in the control of resource use, anytime and anywhere, while delivering the required computing power. CC model value proposition is that resources are no longer idle most of the time, as they are almost used to the fullest (with lower unit costs). The purpose of this research is to understand how the decisions are made for the purchase, hiring and operation of CC services in large organizations operating in Brazil. In order to achieve this objective, we prepared an Analysis Method to adopt CC based on elements found in literature. Such elements are those factors associated to the adoption of CC such as advantages, challenges, risks and barriers and core capabilities for managers to achieve business objectives (BOB), perform management of IT function (MNG), provide quality of services (QAS) and manage architecture decisions (ARC), considered essential for operation of IT areas of organizations. The study also investigated how CC can contribute with IT strategic alignment with business of these organizations. The methodology employed is multiple cases study, applying the Analysis Method in four organizations, through interviews with main IT executives capable of influencing decisions to adopt or increase cloud adoption. The results obtained show feasibility and applicability of Analysis Method. By mapping factors associated with adoption, the decision making process may be better understood, allowing organizations to better structure approval process and the adoption itself. In cases studied it is possible to note how the adoption of cloud computing contributes with strategic alignment of IT with business.
