| dc.description.abstract | O constante desenvolvimento tecnolĆ³gico proporciona rĆ”pidas mutaƧƵes ao nĆvel das Tecnologias de InformaĆ§Ć£o e ComunicaĆ§Ć£o, no entanto considerando a atual conjuntura socioeconĆ³mico a AdministraĆ§Ć£o PĆŗblica e, nomeadamente a AdministraĆ§Ć£o Local, vivem momentos delicados e aos Chief Information Officer exigem-se soluƧƵes de baixo Capex, mas que nĆ£o descorem o objetivo principal; o aumento de produtividade, levando a que se ponderem soluƧƵes inovadoras, de rĆ”pida implementaĆ§Ć£o, mas de baixo custo. O objetivo geral desta dissertaĆ§Ć£o, consiste em analisar o impacto da adoĆ§Ć£o da cloud computing na AdministraĆ§Ć£o Local, mais concretamente a migraĆ§Ć£o de aplicaƧƵes, onde se pretende estudar uma soluĆ§Ć£o de baixo Capex, que permita simultaneamente a reduĆ§Ć£o do Opex, sendo primordial a obtenĆ§Ć£o de respostas, atravĆ©s de um estudo de caso. Para a sua concretizaĆ§Ć£o, adotou-se uma metodologia, que contempla o mĆ©todo qualitativo, cujo procedimento metodolĆ³gico Ć© o estudo empĆrico, baseado na investigaĆ§Ć£o da literatura referente ao novo paradigma da cloud, o seu modelo de computaĆ§Ć£o assim como as vantagens e desvantagens para a autarquia estudada. Da pesquisa efetuada, concluiu-se que a mudanƧa de paradigma, nĆ£o se torna tĆ£o disruptiva pela parte tecnolĆ³gica, mas sim pela forma da sua utilizaĆ§Ć£o, ou seja, a transiĆ§Ć£o da computaĆ§Ć£o tradicional para um novo modelo onde o consumo de recursos computacionais, serĆ” realizado atravĆ©s de serviƧos, influenciando ainda mudanƧas a nĆvel econĆ³mico e contabilĆstico, onde o software e hardware passam a ser adquiridos como um serviƧo, sendo contabilizados, ao invĆ©s do que se passava anteriormente que eram capitalizados no balanƧo anual. Foi ainda possĆvel concluir, que a problemĆ”tica deverĆ” ser devidamente pensada no sentido de refletir as questƵes subjacentes ao nĆvel do enquadramento legal, seguranƧa da informaĆ§Ć£o, interoperabilidade, entre outros aspetos considerados prementes Ć temĆ”tica. No estudo de caso concluiu-se a viabilidade de migraĆ§Ć£o do email para a cloud pĆŗblica, ao invĆ©s das aplicaƧƵes core, as quais pela sua criticidade, fator estratĆ©gico, seguranƧa e ausĆŖncia de leis especificas nĆ£o se aconselha de imediato a sua migraĆ§Ć£o. | por |
| dc.description.abstract | The constant technological development provides rapid changes at the level of Information Technology and Communication. However considering the current socio-economic situation and public administration, including Local Government, we are living delicate economic moments. Top management requires to Chief Information Officers solutions of low Capex but these solutions cannot overcome the main organization goal: increase productivity, leading to solutions that consider innovative and rapidly deployable but with low cost. The overall goal of this dissertation is to analyze the impact of cloud computing adoption in Local Government specifically the applicationsā migration. Through a case study is it expectable to achieve a low Capex solution, allowing both Opex reductions. To analyze and understand cloud computing achievement, the adopted case study methodology is a qualitative method and the methodological procedure is empirical, research-based literature about the new cloud paradigm, its computing model as well as the advantages and disadvantages for autarchies. From the conducted research it was concluded that the paradigm shift it is not so technological disruptive but it is disruptive from its use. In other words, the transition from traditional computing to a new model (where the consumption of computing resources will be accomplished through services) will influence changes in the economic and accounting issues. Software and hardware will be purchased as services rather than what was happening previously (capitalized on balance sheet). Also, it was still possible to conclude that this thematic should be properly designed in order to reflect the underlying issues at the level of the legal framework, information security, interoperability, among other aspects. After case study approach it is viable to say that autarchy could migrate email to public cloud, instead of the core applications (which by its criticality, strategic factor, safety and absence of specific laws should not be immediately migrated). | en |
