The cloud computing field had many advances in the last years and new classifications proliferated in a discretionary way. Despite some attempts, there is still no agreed taxonomy. This paper analysis the related literature and practical implementations describing the diverse identified classifications. The analyzed information is structured into a new proposal of service classification model. It is also demonstrated that some of the created classifications do not help the clarification of this new paradigm. Numerous discretionary classifications of cloud computing services appeared in the last years, increasing the entropy on this new computing model. Some literature tried to define and organize the diverse classifications, but none has yet covered the broadness of the existing work in this field.
