Yiannis Verginadis presenting our research on proactive and polymorphic adaptation of multi-cloud deployments during the 1st Horizon Cloud Summit 2020. Our work is carried out within the H2020 Morphemic research project. During the summit we provided an introduction to multi-Cloud application modelling, configuration, deployment, and adaptation, including a survey of the existing Cloud Management Platforms (CMP), modelling methods, and languages. Moreover, we provided an overview of the latest research and a comparison of different Cloud Management Platforms (such as Cyclone RightScale and Google Cloud Anthos).
