Abstract(s)
Esta dissertação aborda a cloud computing como um conceito que tem evoluído nas
áreas de Tecnologias de Informação e Comunicação (TIC). O conceito de Cloud computing
segundo o NIST (National Institute of Standarts and Technology), é composto por cinco ca racterísticas fundamentais que o distingue do modelo tradicional, três modelos de serviços
essenciais que constituem os alicerces na entrega de infraestrutura de Tecnologias de Infor mação (TI) e por quatro modelos de implementação que definem como o conceito de Cloud
é entregue na sua abstração (NIST, 2011). Este novo conceito representa um novo desafio
para a gestão das organizações na medida que promove uma reorganização de toda ou parte
da infraestrutura tecnológica das organizações. É importante ressaltar que a Cloud computing
não é um modelo ou conceito disruptivo na sua abrangência, sendo que representa uma evo lução natural dos modelos anteriores de TIC. Esta evolução deu-se através do condiciona mento e da evolução de várias outras tecnologias, como, a Internet de banda larga, virtuali zação, comunicação por fibra ótica ou a capacidade de computação a preços competitivos.
As contribuições desta dissertação incluem dar uma visão da contribuição do conceito
de Cloud computing na elaboração de infraestrutura de TI e como esta poderá atuar como
modelo de adoção em TIC por parte das organizações e responder as questões levantadas
durante a etapa da construção da problemática:
• Como as organizações poderão utilizar a Cloud computing para redução de custos de
infraestrutura TIC? Como poderão utilizar o conceito de elasticidade presente no con ceito de Cloud para dimensionar a infraestrutura de TIC de acordo com as suas ne cessidades?
• Qual o impacto da Cloud computing nos processos organizacionais através da subs tituição das infraestruturas On-Premise?
Esta dissertação foi conduzida utilizando a investigação qualitativa, uma vez que per mite ter uma visão global alargada do fenómeno em estudo. O modelo de pesquisa utilizado
foi de carácter descritivo por ser uma pesquisa que permite aprofundar a temática em estudo
tendo em conta uma revisão aprofundada da literatura, e desta forma, aumentar os conheci mentos sobre os factos estudados bem como estruturar a dissertação no sentido de obter as
respostas para as questões levantadas na investigação.
De forma a suportar as questões de investigação, a dissertação assenta no estudo de
uma proposta de implementação na adoção da Cloud computing em uma organização, no
sentido de responder às suas necessidades internas e externas utilizando e moldando os
vários serviços associados a Cloud na sua realidade organizacional
This dissertation approaches Cloud computing as a concept that has evolved in the areas of Information and Communication Technologies (ICT). The concept of Cloud compu ting according to NIST (National Institute of Standards and Technology), is composed of five fundamental characteristics that distinguish it from the traditional model, three models of es sential services that constitute the foundations in the delivery of Information Technology infra structure (IT) and by four implementation models that define how the Cloud concept is deliv ered in its abstraction. This new concept represents a new challenge for the management of organizations as it encourages a reorganization of all or part of the organization´s technologi cal infrastructure. It is important to highlight that Cloud computing is not a disruptive model or concept in its scope, as it represents a natural evolution of previous ICT models. This evolution took place through the conditioning and evolution of several other technologies such as Inter net, virtualization, optical fibre communication or computing capacity at competitive prices. The contributions of this dissertation include giving a vision about the concept of cloud computing in the development of IT infrastructure and how it can be a model for the adoption of ICT by organizations and answering the questions raised during the construction phase of the problem: • How can organizations use the concept of Cloud computing to reduce ICT infrastruc ture costs? How can they use the concept of elasticity present in the Cloud concept to scale the ICT infrastructure according to their needs? • What is the impact of the Cloud computing concept on organizational processes through the replacement of On-Premise infrastructures? This dissertation was conducted using the qualitative methodology, since it allows to have a comprehensive global view of the phenomenon under study. The research model used was descriptive because it is a research that allows to expand the theme under study, and in this way, to increase knowledge about the facts studied and to structure the dissertation to find the answers to the questions raised in the search. To support the research questions, the dissertation is based on the study of an imple mentation proposal in the adoption of Cloud computing concept in an organization, to have answers to their internal and external needs using the various services associated to the Cloud.
