Purpose:
Main purpose of F-GPS (a.k.a. Valet) is, with considering placement rules, (1) to precisely check capacity & capability of target DC or edge site and then, (2) to determine VNF placements.
- Placement rules include Affinity and Anti-affinity.
- Scopes of placement rules are, in a target DC or edge site, across availability-zones and optionally, across compute hosts.
- Applications of placement rules are workloads within a VNF or workloads across VNFs.
- Opportunity to standardize many other placement rules (e.g., Exclusivity, Quorum-Diversity) in VNFD and Policy.
