This thesis is based on my work experience in a project carried out by NTT Data Italia, for one of its major client in the media sector, to design and implement a real time Big Data Platform on a cloud environment. The goal of this project is to guide the client in the evolution of his technologies for the management of the data migrating from an architecture based on several data warehouses to a single data lake that centralized all data. This new platform allow the client's business users to perform their analyses more easily, quickly and accurately and enable data scientist to develop their prediction models joining data from different data sources and departments.
