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
2. MultiCloud API definitions
Multi-Cloud provides the following interfaces:
Interface Name | Interface Definition | 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)
- 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)
|
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
MultiCloud consumes the following Interfaces:
Interface Name | Purpose Reason For Use |
---|
SDCE-6 | To receive the cloud orchestration artifact from SDC |
MCE-1 | Consume the services from the cloud provider. It is specific to each cloud type (by plugin approach) |
DCAEE-X | Supply Virtual Infrastructure FCAPS Events to DCAE |
AAIE-1 | Consume the services from AAI to access infrastructure resource inventory |
