HPA SO External Sequence Flow for Casablanca
HPA SO External API Interaction for Casablanca
Policy
Still Under Discussion: Utilize existing SO generic-rest-adapter. This is a possible interaction with Policy to obtain service specific flow path decision for Service Model.
OOF
Still Under Discussion: Utilize existing SO Homing code. SO will adhere the OOF/SO R2 APIs updated for R3 to fix issues from R2 and include passing on a set of generic key value pairs that could contain such values as flavor_name:HPA2 or SRIOV attributes. These key value pairs will be passed to Multicloud during instantiation as OOF_Directives.
Addition of oofDirectives as part of
"assignmentInfo"
to R2 (doesn't change api):

}MultiCloud
Still Under Discussion: Utilize existing so-opendstack-adapter and extend, or clone to so-multicloud-adapater and extend. Use Multicloud OpenStack Proxy API and extend HEAT API payload with generic-vnf-id, vf-module-id, oof_directives, sdnc_directives and template_type.
