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.

| 5G VNF teaming (TBD) | TBD | TBD |
5G VNFs teaming use case: A VNF instance has 2 workloads (2 VM instances) that must be placed in a same zone (or compute host) because of the high throughput requirement between workloads. Meanwhile, 2 more replicas of the VNF instance must be placed in different zones (or different compute hosts) of the same DC because of the high-reliability requirements for the VNF.
To meet these requirements, each VNF instance must specify an Affinity rule for its 2 workloads. Meanwhile, the same type of workloads in those 3 VNF instances must specify an Anti-affinity rule.
