MYRTUSDesigner

TOSCA Designer is an open-source module for Modelio 5.4.1, enabling graphical modeling of cloud-based applications using the OASIS TOSCA Standard. It allows users to specify the components comprising the topology of cloud-based applications along with the processes for their orchestration. TOSCA supports the specification of types and templates. It also allows exporting these models as .tosca and .csar files.
