MC Multi-Cloud:

1 High Level Component Definition and Architectural Relationships 





The multi-cloud function provides mediation capabilities to connect to different infrastructure providers.

  • Adapt ONAP to VM based infrastructure such as openstack,Azure

  • Adapt ONAP to Container Orchestration Engine, such as K8S

  • Discovery and registration of resource information.

  • Relay FCAPS data from infrastructure to DCAE

 Interface Capabilities

MCE-2

Resource Lifecycle Management Interface

Provides a course grain VNF level LCM interface in a template driven and cloud agnostic way

 Provides:

  • Infrastuture workload LCM (instantiate, query, Delete Infrastructure workloads)



MCE-3 

 N/A Place holder for SDN interconnect interface

Envisaged Future Capability

MCE-4 

Atomic Resource LCM

Provides a fine graned resource LCM interface at the VM level. This is an atomic resource level workload LCM (specific to openstack resources)

Provides:

  • Image Management: (Create/Delete/Get Images)

  • Network Management (Create/Delete/Query connectivity)

  • Subnetwork Management ((Create/Delete/Query sub-networks)

  • Flavour Management (Create/Delete/Query VM Flavors)

  • Volume Management (Create/Delete/Query Storage Volumes)

  • Tenant Management (Create/Delete/Query Infrastructure Tenants)



MCE-5 

Placement Optimization Interface

Provides real time available capacity information

Provides:

  • Query for real-time available capacity information

MCE-6 

Cloud VIM Registration interface 

Expose Interface to trigger MultiCloud plugin to discover the infrastructure resource and register them to AAI

Provides:

  • VIM Management (Update VIM info, unregister VIM info)

Note:   xxxI interface is a Component internal interface.  xxxxE interface is a component external interface

The current API documents can be found at: https://onap.readthedocs.io/en/latest/submodules/multicloud/framework.git/docs/MultiCloud-APIv1-Specification.html
