Location 

Existing Service location.

Given the service details identify the cloud-region and the location details from complex.

Since this is a service we need to identify where it can get cloud-region and Complex

service-instance → cloud-region → complex  → (lat,long)

CloudAffinity

Given a cloud-region identify the location details from complex.

generic-vnf → vserver → pserver → cloud-region → complex  → (lat,long)

generic-vnf →  complex  → (lat,long)

resolve_host_location

Given an opaque host name that can be translated to a coordinate via A&AI.

???

resolve_clli_location

/cloud-infrastructure/complexes/complex/' + clli_name

Who populates this information?

Unknowns :

• Does VIM onboarding ensures the complex information is populated and the relationship between Cloud-region and complex established? 
• Confirm with ESR if this association between complex and cloud-region will be taken care
• Who populates info on location(complex)?

HPACapabilities

Given a list of HPACapabilities as requirements, identify the candidate list of cloud regions and flavor reference associated with these cloud-regions

• Get list of cloud regions matching all the mandatory HPA capabilities.
• Filter by selecting cloud-regions that have existence of flavor-references associated with all HPACapabilties from requirement. (This will help to fetch the cloud regions and flavor with all capabilities satisfied)
  
  

Min Guarantee Capabilities

Get a list of canditate cloud regions and flavor references that satisfies the minimum guarantee requirements. For eg: cpu = 4, memory = 8GB

Question : Similar to HPACapabilities. Can we rely on flavors to get this information?
