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/…

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
