Purpose:

Main purpose of F-GPS (a.k.a. Valet) is, with considering placement rules,  (1) to precisely check capacity & capability of target Cloud Region and then, (2) to determine VNF placements (i.e., target zone or compute host for each workload of VNF).

Dublin Focus:

• 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.
