• For each cloud owner
  • Map VNFC to Instance Type
    • One or more VNFCs (e.g. vCPE VGW) could map to an instance type
      • Use Case: Residential Broadband vCPE (Approved)
      • https://github.com/onap/demo/blob/a19bd423c1e4d2f5552bab090ba2650c38fa7192/heat/vCPE/vgw/base_vcpe_vgw.yaml
    • Convert to appropriate instance type based on intent //e.g. "Infrastructure Resource Isolation for VNF" may result in a different instance type if the cloud owner supports supports "Burstable QoS"
  • For each cloud region // Public cloud could have different costs in different geographic locations
    • net_value_cost = net_value_cost + cost_instance_type // cost per instance type is based on policy (for R3, it is picked up from Multi Cloud configuration file)
    • net_value_cost = net_value_cost + cost_intent //e.g. "Infrastructure High Availability (HA) for VNF" may have additional cost

...

• • • If infra capacity is finite (Private cloud or Public cloud with on-demand instances) // e.g. object of interest is OpenStack Project with a quota (upper limit)

...

• • • for cpu, mem and local disk
      • normalized_cpu_per_object = (current_cpu_used_object + instance_type_cpu)/current_cpu_used_object
        • if normalized_cpu_per_object > 1, capacity check failed
      • normalized_mem_per_object = (current_mem_used_object + instance_type_mem)/current_mem_used_object
        
        • if normalized_mem_per_object > 1, capacity check failed 
      • normalized_disk_per_object = (current_disk_used_object + instance_type_disk)/current_disk_used_object
        • if normalized_disk_per_object > 1, capacity check failed 
      • net_value_capacity = normalized_infra_capacity = wcpu*normalized_cpu_per_object + wmem*normalized_mem_per_object + wdisk*normalized_disk_per_object // wcpu, wmem, wdisk are specified in a multi-cloud configuration file; wcpu + wmem + wdisk = 1
• Initial Cost
  • Cost of Instance Type 
• Operational Cost 
  • Instance Type  
  • Features
    • "Infrastructure High Availability (HA) for VNF" 
    • "Infrastructure Resource Isolation for VNF" 
      • If "Burstable QoS" is supported, use the corresponding cost -- Else use the cost for "Guaranteed QoS"
