Hi Alexis, Dan,
I am not sure if you are aware the ONAP functional requirement
about the “Centralized Representation and Consistent Identification of Cloud
Regions In
ONAP<https://wiki.onap.org/display/DW/Centralized+Representation+and+Consistent+Identification+of+Cloud+Regions+In+ONAP>”
https://wiki.onap.org/display/DW/Centralized+Representation+and+Consistent+Identification+of+Cloud+Regions+In+ONAP
The functional requirement consists of 2 important changes:
1, remove any hardcoded/redundant representation of a single cloud region, the
hard-coded cloud-sites in SO configuration file is exactly what is targeting
to be refactored. Now this part is on track of pairwise testing between
SO/MultiCloud .
2, apply the usage of ID of a cloud region in a consistent way , the agreement
is that the composite keys: {cloud-owner}/{cloud-region-id} will be applied
whenever ONAP component wants to refer to a cloud region. This part requires
the API changes between VID/SO/SDNC and other related projects. It is a
stretch goal in Casablanca, perhaps we can get it done in Dublin Release.
I do believe both of 2 changes above might be related to your
proposal. I would like to discuss a little bit about the issue and your
proposal so that maybe we can come up with more comprehensive/consistent
solution to get things (API changes) done at one time.
If you don’t mind, we can start with several questions:
1, why should the Cloud-Owner be provisioned to SDNC with
REST-API?
I guess your proposal is to provision the “Cloud Owner” instead of having it
being hard-coded . I agree with you that it should not be hard-coded, but why
should the Cloud-Owner be provisioned to SDNC with REST-API?
IMHO, “Cloud-Owner” (and the cloud-region-id ) should be selected either by
user via VID portal or by OOF according to policy. In that case, the ID of the
selected cloud region ({cloud-owner}/{cloud-region-id} ) should be passed to
SO/SDNC/etc. through rest API.
2, Will SDNC use the ID of the selected cloud region to retrieve information
from AAI?
This question is to help me understand what the interactions are
between SDNC and AAI
3, Will SDNC use the ID of the selected cloud region to retrieve information
from underlying VIM/Cloud instance (e.g. OpenStack instance)?
This question would help me understand if there is interaction
between SDNC and underlying VIM/Cloud instance
Thanks

Subject: [onap-tsc] [TSC] Request API change waiver between SO and SDNC
Hello TSC,
As discussed during today’s meeting, an issue has been identified in the new SO
building block, introducing a regression in term of functionality from previous
release.
PTLs from both projects acknowledge and agree with the required changes.
Expected behaviour:
Have the cloud owner / cloud region being retrievable from static configuration
file.
Current behaviour:
Cloud owner is hardcoded in the code, with no way to change it using config
file.
API change requested:
SDN-C: GENERIC-RESOURCE-API.yang
Impact:
This API change will allow SO to resolve the cloud owner from the config file
(similar to what we had in previous release), and to be able to use it with the
GR-API.
Patches:
SO:
1. Use a property instead of hard coded value. (TBD)
2. Push the changeset to allow it to be set on the north-bound
api. (TBD)
SDNC:
1 Add cloud-owner definition: .https://gerrit.onap.org/r/#/c/67413/
Regards,
Alexis
