To properly deal with volume, velocity and variety data dimensions in educational contexts is a major concern for Educational Institutions and both Educational Data Mining and Learning Analytics Researchers have cooperated to properly address this challenge which is popularly called Big Data. Hardware developments have been made to increase computing power, storage capacity and efficiency in energy use. New technologies in databases, file systems and distributed systems, as well as developments in data transmission techniques, data management, data analysis and visualization have been trying to overcome the challenge of processing, storing and analyzing large volumes of data and the inability to meet simultaneously the requirements of consistency, availability and tolerance of partitions. Although the architecture definition is the main task in a Big Data system design, objective guidelines for the selection of the architecture and the tools for the implementation of Big Data systems were not found in the literature. The present research aims to analyze the main architectures for both batch and stream processing and to use one of them in the construction of a Big Data environment, providing important orientations to Researchers, Technicians and Managers. Academic data and logs of the Virtual Learning Environment Moodle of an Academic Unit of a Higher Education Institution are used.
