Economic model and analysis of the cloud

[EN] This final degree project analyzes the Cloud Computing situation in the world with a focus on the Spanish case, and models the Cloud Computing supply and demand. Different analysis about the Cloud Computing economic model have been carried before but either they focus on the general terms of Cloud, or they focus on specific service models. We tried to give a global perspective including all three main services. In order to do that, it focuses on the definition of the Cloud Computing and its elements, and the factors that may influence the demand and supply. Then, some theories are considered, and a scenario-case has been calculated to help understand how the supply meets the demand and its applications. At the final section, the conclusions about the different Cloud Computing elements, and factors that affect its adoption have been summarized and a forecast about future developments in the industry closes the paper.
[ES] Las empresas, tanto tecnológicas como no tecnológicas, están cambiando progresivamente la gestión de su infraestructura de tecnologías de la información y comunicación hacia el paradigma de cloud computing o computación en la nube. O dicho de otro modo, existe una en la que los recursos físicos de los departamentos de sistemas de información tienden a externalizarse. Ante una decisión de este calado, resulta conveniente disponer de modelos económicos adecuados que evalúen los costes y beneficios de adoptar este paradigma. El objetivo de este trabajo es revisar los principales modelos económicos de cloud computing , determinar las variables principales que intervienen en la decisión de adoptar la nube, y aplicarlos los modelos en diversos escenarios.
