3. Release 1 API Design
All API starts with MultiCloud Name Space, followed by functional module name space
/namespace_root/multicloud/v0/….../...... /
Support existing OpenStack APIs as default functional modules. Minimal code changes to existing ONAP modules that already use OpenStack.
/namespace_root/multicloud/v0/v2.1/servers/…
/namespace_root/multicloud/v0/v2.0/network/...
New name space for common cloud functionality.
/namespace_root/multicloud/v0/proton/network/
/namespace_root/multicloud/v0/register/…
/namespace_root/multicloud/v0/fcaps/…
/namespace_root/multicloud/v0//resmgt/...
Also support 3rd party extension beyond common functionalities
/namespace_root/multicloud/v0/extension/…

7. Steps Registry Service Access
User inputs backend Cloud information into ESR portal
ESR stores the backend Cloud information as auth model into AAI, key is cloudowner_cloudregion
User triggers VIM register service exposed by Multi VIM which will trigger registry implements in different VIM plugins to fill in VIM Model information into AAI
Each plugin handles AAI query about the backend Cloud information for backend Cloud operations
Service Access
Controller which rely on openstack APIs creates service client and get keystone token by Multi VIM/Cloud service url.
Multi VIM/Cloud service returns tokens and the catalog of endpoint list which are SBI defined by different plugins
Controller will use the composition of returned endpoints and service API for the following OpenStack API access
Multi VIM/Cloud translates the composted service API into the required OpenStack API then return the reponse to the caller

8. API List Multi VIM/Cloud registry
msb.onap.org:80/api/multicloud/v0/{cloud owner}_{region}/registry
Cloud Region and auth information is documented and reviewed by AAI team
Multi VIM/Cloud OpenStack compatible service

Multi VIM/Cloud service consumer
