Cloud-agnostic Placement/Networking & Homing Policies (Phase 1 - Casablanca MVP, Phase 2 - Stretch Goal)

Value:

End-to-end use case Applicability:

• All (especially the data plane VNFs with fine-grained VNF placement and high performance networking requirements)

Value:

• Improve "workload deployability" by avoiding exposure of "cloud specific" capabilities to several ONAP components and addressing "separation of concerns" VNF Placement & High Performance Networking for all use casesImprove Workload Deployability through Cloud-Agnostic Intent for Intra-DC Placement & Networking
• Support capacity check (besides capability check) for HPA resources 
• Applicable to all workloads - VM-based or Container-based
  
  

Phase 1 Summary:

• Multi-Cloud Policy Framework
  • Assist OOF in target cloud region selection for VNF placement (aka homing) by summarizing cloud-specific capability, capacity & cost metrics (e.g. anti-affinity for VMs in a VNF could have different cost in different clouds)
  • Dynamically modify the cloud specific VNF deployment template based on cloud-specific realization of the specified intent with no impact to VNF configuration (e.g. anti-affinity could have different realizations across different clouds)
• Intent Support
  • Single realization option per Cloud Region
• Major Impact Projects:
  • Multi-Cloud (Highest), OOF
• Minor Impact Projects:
  • A&AI, SO

Phase 2 Summary (Build on Phase 1 Work):

• Multi-Cloud Policy Framework
  
  • Dynamically modify the cloud specific VNF deployment template based on cloud-specific realization of the specified intent with impact to VNF configuration (e.g. 
• Intent Support
  • Multiple realization options per Cloud Region
• Major Impact Projects:
  • Multi-Cloud (Highest), OOF
• Minor Impact Projects:
  
  • GNF ControllerAddresses separation of concerns in exposing Cloud-specific capabilities to
