Abstract:
The continuous development of cloud computing is in evidence in several academic and non-academic researches. However, the relative youth of this field has produced several distinct definitions and taxonomies regarding the concept of cloud computing, as well as the classification and organization of such services. The appearance of commercial cloud solutions in this context with no firmly established standards only complicates the matter, making it difficult to determine how solutions should be technically identified and qualified. Therefore, with the growing complexity of the area, identifying, clarifying and classifying cloud services are essential steps to understand their organization, purpose and interaction with other services. With this goal in mind, this article presents a study on existing concepts and taxonomies, and then harmonizes these approaches in an extensible taxonomy model for cloud computing services. More specifically, this proposal builds on the SPI (Software, Pl
atform, and Infrastructure) taxonomy created by NIST (National Institute of Standards and Technology), creating a hierarchical organization that groups different services according to their characteristics; the result is a taxonomy model that allows finer-grained analyses to be performed, while essentially keeping the simplicity of SPI itself. Finally, we present a specific instance of this model focused on existing and representative cloud services.
