The multi-cloud function provides mediation capabilities to connect to different infrastructure providers.
- Connect Adapt ONAP to VM based infrastructure such as openstackContains container based Orchestration engine and infra structure levelLCM of VNFs for container based VNFs,Azure
- Adapt ONAP to Container Orchestration Engine, such as K8S
- Discovery and registration of resource information.
