How does an S-VNFM register? Is it still via Multi-Cloud?
Byung-Woo Jun
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 https://docs.onap.org/en/casablanca/submodules/aai/esr-server.git/docs/platform/architecture.html.
