The conceptual design provides a high-level view of the roles, areas of responsibility, and tenant flow that are required to upload an image, onboard, and deploy it.

The VNF onboarding process is typically a collaborative effort between the VNF vendor and the CSP. Before a VNF is onboarded, the VNF vendor must provide the CSP with all the prerequisites for the successful onboarding of the VNF. This includes information such as the VNF format, number of the required networks, East-West and North-South network connectivity, routing policy, security policy, IP ranges, and performance requirements.
