Cloud Modeling Languages by Example

Recently, several proposals towards a cloud modeling language have emerged. As they address the diversity of cloud environments, it is not surprising that these modeling languages support different scenarios. Using a by-example approach based on the scenario of software migration, we demonstrate their representational capabilities and review them according to characteristics common to all modeling languages as well as specific to the cloud computing domain. We report on our findings and present research guidelines for future efforts towards a better alignment of the different cloud modeling languages.
