  1. How does an S-VNFM register?  Is it still via Multi-Cloud?  

  2. Hi Rebecca, In Dublin, an S-VNFM is registered to the ESR through the ESR GUI and/or command line, no Multi-Cloud was involved for the S-VNFM registration. Then ESR stores the registered info to A&AI. The VNFM Adapter queries the VNFM info from A&AI.

    Please take a look at the VNFM registration sequence diagram at
