MC Multi-Cloud:

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

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)



https://docs.onap.org/projects/onap-multicloud-framework/en/latest/MultiCloud-APIv1-Specification.html

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)

  • Virtual Point Management (Create/Delete/Query Virtual endpoints)

  • Server Management (Create/Delete/Query Virtual Servers)

  • Heal Server

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

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

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



https://docs.onap.org/projects/onap-multicloud-framework/en/latest/MultiCloud-APIv1-Specification.html

MCE-5 

Placement Optimization Interface

Provides real time available capacity information

Provides:

  • Query for real-time available capacity information

https://docs.onap.org/projects/onap-multicloud-framework/en/latest/MultiCloud-APIv1-Specification.html

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)

https://docs.onap.org/projects/onap-multicloud-framework/en/latest/MultiCloud-APIv1-Specification.html

MCE-7

CNF Lifecycle Management Interface

Provides a course grain CNF level LCM interface for k8s workloads based on helm resource templating format.

The interface differs from MCE-2 because of the different modeling applied for CNFs in comparison to VNFs - RB (Resource Bundle) concept which represents helm package encapsulation.

Provides:

  • RB Definition Management (Create/Delete/Get RB Definition)

  • RB Definition Content Management (Update RB Definition Content)

  • RB Profile Management (Create/Delete/Get RB Profile)

  • RB Profile Content Management (Update RB Profile Content)

  • RB Instance Management (Create/Delete/Get RB Instance)

  • RB Configuration Template Management (Create/Delete/Get RB Configuration Template)

  • RB Configuration Template Content Management (Update RB Configuration Template Content)

  • RB Configuration Instance Management (Update RB Configuration Instance)

  • Query API for cluster resources

  • Helm 3 support

  • Query API notifications (stretch)

MultiCloud K8s-Plugin-service API

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