Por isso, a Governan?a de TI ? vista com uma das prioridades das organiza??es no momento. A busca pelo alinhamento estrat?gico entre neg?cio e TI ? debatida como um fator relevante para o sucesso empresarial, mas mesmo com essa import?ncia, normalmente os principais gestores de neg?cio relutam em assumir a responsabilidade das decis?es que envolvem a TI. Tudo isso, devido a complexidade de sua infraestrutura. J? a computa??o em nuvem vem sendo vista como um elemento capaz de auxiliar na implanta??o das estrat?gias organizacionais, em virtude de suas caracter?sticas permitirem uma maior efici?ncia e agilidade da ?rea de TI, sendo considerada como um novo paradigma computacional. O objetivo principal do estudo foi analisar as rela??es entre os arranjos de governan?a de TI e o alinhamento estrat?gico com a infraestrutura como servi?o (IaaS) da computa??o em nuvem p?blica. Para tanto, foi desenvolvida uma pesquisa explorat?ria, descritiva e inferencial com abordagem ao problema da pesquisa de forma quantitativa, utilizando o m?todo survey descritiva e de corte transversal. Foi utilizado um question?rio eletr?nico aplicado com os Associados do ISACA dos chapters do Estado de S?o Paulo e Distrito Federal, totalizando 164 respondentes. O instrumento utilizou como base as teorias de Weill e Ross (2006) para matriz de arranjo de governan?a de TI; Henderson e Venkatraman (1993) e Luftman (2000) para modelo de maturidade do alinhamento estrat?gico e NIST (2011 b), ITGI (2007) e CSA (2010) para maturidade da infraestrutura como servi?o (IaaS) p?blica em suas caracter?sticas essenciais. No tocante aos principais resultados, esta pesquisa comprovou que com a IaaS p?blica as estruturas de tomada de decis?o foram alteradas, havendo uma maior participa??o dos altos executivos em todas as cinco decis?es-chave de TI (matriz de arranjo de governan?a de TI), inclusive decis?es mais t?cnicas como arquitetura e infraestrutura de TI. Foi observada, tamb?m, a diminui??o na participa??o dos especialistas de TI, caracterizando-se o processo de decis?o com o arqu?tipo duop?lio (decis?o compartilhada). No quesito alinhamento estrat?gico foi observado que este ? alterado com a computa??o em nuvem, tendo as organiza??es com IaaS p?blica uma maturidade do alinhamento estrat?gico com diferen?a estatisticamente significativa e superior, quando comparada com as organiza??es sem IaaS. A maturidade da IaaS p?blica se encontra no n?vel intermedi?rio (n?vel 3 - ?processo definido?), tendo a elasticidade e mensura??o obtido o n?vel 4 - ?gerenciado e mensur?vel?. Diante disso, foi poss?vel inferir que nas organiza??es com IaaS p?blica h? correla??es entre as decis?es-chave e a maturidade da IaaS, principalmente em princ?pios, arquitetura e infraestrutura de TI e com os arqu?tipos que envolvem altos executivos e especialistas de TI, al?m da correla??o entre a maturidade do alinhamento estrat?gico e a maturidade da IaaS p?blica. Portanto, quanto maior o alinhamento estrat?gico, maior a maturidade da IaaS p?blica e vice-versa. / Increasingly, the Information Technology (IT) has been used to sustain the business strategies, causing increased its relevance. Therefore IT governance is seen as one of the priorities of organizations at the time. The search for strategic alignment between business and IT is debated as a factor for business success, but even with that importance, usually the main business managers are reluctant to take responsibility for decisions involving IT, mainly due to the complexity of your infrastructure. Since cloud computing is being seen as an element capable of assisting in the implementation of organizational strategies, because their characteristics enable greater efficiency and agility in IT, and is considered as a new computing paradigm. The main objective of the analyze the relationship between IT governance arrangements and strategic alignment with the infrastructure as a service (IaaS) of public cloud computing. Therefore, an exploratory, descriptive and inferential was developed, with approach to the problem of quantitatively research, with descriptive survey method and cross section. An electronic questionnaire that was applied to the ISACA chapters Associates of S?o Paulo and the Distrito Federal, totaling 164 respondents was used. The instrument used based on the theories of Weill and Ross (2006) for array of IT governance arrangement; Henderson and Venkatraman (1993) and Luftman (2000), for maturity of the strategic alignment model; and NIST (2011 b), ITGI (2007) and CSA (2010) for infrastructure maturity as a service (IaaS) public in its essential characteristics. As regards the main results, this research proved that with public IaaS decision-making structures have changed, with a greater participation of senior executives in all five key IT decisions (IT governance arrangement array) including more technical decisions as architecture and IT infrastructure. With increased participation of senior executives the decrease was also observed in the share of IT specialists, characterizing the decision process with the duopoly archetype (shared decision). With regard to strategic alignment, it was observed that it changes with cloud computing, and organizations with public IaaS, a maturity of strategic alignment with statistically significant and greater difference when compared to organizations without IaaS. The maturity of public IaaS is at the intermediate level (level 3 - "defined process"), with the elasticity and measurement achieved level 4 - "managed and measurable" It was also possible to infer in organizations with public IaaS, there are positive correlations between the key decisions and the maturity of IaaS, especially at the beginning, architecture and infrastructure, and the archetypes involving senior executives and IT specialists. In the correlation between the maturity and mature strategic alignment of public IaaS therefore the higher the strategic alignment, the greater the maturity of the public IaaS and vice versa.
