- New placement policies include Affinity and Anti-affinity.
- Scopes of Affinity/Anti-affinity are, in a target Cloud Region, across Availability-zones and optionally, across compute hosts.
- Applications of Affinity/Anti-affinity are workloads (VDUs) within a VNF or workloads across VNFs.
- Opportunity to standardize many other placement policies (e.g., Beside Affinity/Anti-affinity, include Exclusivity, Quorum-Diversity, etc.) in VNFD and Policy.
- Integrated into OOF/HAS (maybe initially as dark mode (PoC) for evaluation over Dublin).

- Seed code for OpenStack cloud and evaluate in an OpenStack testbed. Later, extend to the other clouds including Azure and AWS.
- Capacity & Capability checking for an OpenStack cloud:
- Checking the number of zones of the target Cloud Region to solve the Anti-affinity rules.
- Checking available capacity of each zone to solve Affinity rule.
- Checking available host profiles of each zone to solve flavor matching (i.e., Host-Aggregates) (Stretch Goal).
- Placement decisions for Affinity and Anti-Affinity among zones of target Cloud Region. Optionally, decisions go into compute hosts (for private cloud case).
- Defining Affinity and Anti-affinity rules in Policy (Stretch Goal). Until this is ready, evaluate with a manual/hard-coded policy.
- Specifying Affinity and Anti-affinity rules in homing/placement request (Stretch Goal). Until this is ready, evaluate with a manual/hard-coded specification.
- Distributed cloud modelling immediately relevant to F-GPS - a single cloud control plane (Cloud Region) to be able manage several distributed DC locations/zones.
Leverage capacity alerts (significant change in capacity) from Model-driven Distributed Analytics work.
