Some extra ONAP terminology
...
In its simplest form, a function does not have an Implementation Topology. Instead, its Interface Type specifies a TOSCA deployment artifact, like a VM or Docker image. This artifact is sufficient for the orchestrator to launch an instance of this function. This artifact is called an Implementation Artifact and effectively represents the SwImage element from the ONAP Info Model. A Function with an Implementation Image represents the VDU element of the Info Model.
