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/…
