SOTA in modeling languages and model transformationtechniques

Description: 

This document gives an overview on the state-of-the-art of modeling concepts in the context of cloud computing. During the last years, several proposals for cloud modeling concepts emerged. However, as diverse as cloud environments are, it is not surprising that also the proposed modeling concepts support different scenarios. By using a running example, we demonstrate the features of current cloud modeling approaches and compare them according to five dimensions. We report on our lessons learned that lead to a list of requirements for future efforts towards a unified modeling language for cloud environments.
