The vLB/vDNS use case requires some changes to support the manual scale out use case. Changes may include, but may not be limited to:

• Adding NETCONF/RESTconf interfaces to VNFs (vLB and vDNS)
• Extending vLB to receive vDNS information (e.g. IP address) from APPC
• Adding health check to the VNFs
• Reshaping the Service structure, with vLB and vDNS as separate VNFs as opposed to separate VF modules of the same VNF
• Moving the telemetry report from the vLB to the vDNS
