The multi-cloud function provides mediation capabilities to connect to different infrastructure providers.

  • Adapt ONAP to VM based infrastructure such as openstack,Azure
  • Adapt ONAP to Container Orchestration Engine, such as K8S
  • Discovery and registration of resource information.
  • Relay FCAPS data from infrastructure to DCAE

MORE functional capabilities?
