  • Seed code for placement decisions 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: 1) Checking the number of zones of the target Cloud Region to solve the Anti-affinity rules, 2) Checking available capacity of each zone to solve Affinity rule, 3) Checking available host profiles of each zone to solve flavor matching (i.e., Host-Aggregates).
  • 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 to be able manage several distributed DC locations/zones. 

  • Leverage capacity alerts (significant change in capacity) from Model-driven Distributed Analytics work.

  • OSDF: support new homing/placement constraints (Affinity, Anti-affinity, and resources per workload (e.g., VM) of VNF) as policies and/or VNFD model.
  • HAS: 1) implement new placement constraints and interact with F-GPS, 2) deal with new placement decisions returned from F-GPS.

  • Collect Availability-Zone capacity data from Clouds.
  • Open new API to communicate with F-GPS for per Availability-Zone capacity checking.
  • Enable the placement decisions (e.g., update Heat env in OpenStack case) to send them to Cloud orchestrator (e.g., OpenStack) via plugins.

  • Open (new) API for F-GPS to obtain Availability-Zone information of each Cloud Region.
  • Distributed cloud modelling immediately relevant to F-GPS - a single cloud control plane to be able manage several distributed DC locations/zones.
