cna.qualityModel.entities.Compute.Infrastructure

The Compute.Infrastructure Node represents an Infrastructure entity. It extends the original TOSCA Compute Node in order to allow a Compute Node to be hosted by another one, which allows representing Infrastructure entities to be hosted by other Infrastructure entities. Additionally, modeled Backing Data can be referenced.
