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

4. Multi-VIM/Cloud Functional Components
Infra Resource
Purpose
Assign initial virtual infrastructure resources and instantiation of VNF
Functionality Overview
API interface
