Centralized Representation and Consistent Identification of Cloud Regions In ONAP

Overview

This is the page to track the realization of functional requirement of "Centralized Representation and Consistent Identification of Cloud Regions In ONAP" to facilitate the orchestration over multiple cloud regions .

The motivation of this functional requirement lies in the fact: with ONAP Amsterdam and Beijing Releases, there are 3 representation of a single cloud region in ONAP, and different ONAP components use different identification to refer to the same cloud region. This complicates the on-boarding process of a cloud region, also imposes unnecessary constraints of the choice of cloud regions,e.g. If there is 2 cloud region with the same cloud region id, only one of them can be on-boarded into ONAP.

The functional requirement is to centralize the representation of the cloud regions into AAI only by depreciating all other representations. All ONAP components should use the composite key of "{cloud-owner}, {cloud-region-id}" to refer to a cloud region.

By enforcing this functional requirement, ONAP users will be able to onboard a cloud region by either issuing a single curl command to AAI service, or a single click over ESR VIM registration GUI portal. The consistent ID of a cloud region will make it is easy to correlate the operations on a cloud region across the all ONAP services.

cloud-region: object  
	cloud-region designates an installation of a cloud cluster or region or instantiation
	...
	...
	cloud-owner: string  
		Identifies the vendor and cloud name. First part of composite key should be formatted as vendor-cloudname

	cloud-region-id: string  
		Identifier used by the vendor for the region. Second part of composite key
