Hi Atif, As far as I know there are no principles defined. But, we did some study on how to integrate domain orchestrators such as “Multi K8S Cluster orchestration” along with other domain orchestrators and also resource orchestrators. There are two ways go about this.
1. A high level service with nested services where nested services handled by various domain orchestrators. 2. A service with resources where resources are handled by domain orchestrators. 3. Of course, combination of both. If you want domain orchestrator to be called from SO/MC, then (2) approach is needed in my view. On (1), I don’t know whether there are any examples. On (2), there are three examples - Multi-Cluster (k8s) orchestration (WIP), Azure Orchestration and AWS Orchestration (AWS is WIP ) In all three examples of (2), each VNF (VF) resource is treated as the self-contained entity. Within Azure/AWS/Multi-Cluster orchestration, they take care of deploying components of VNF in various locations supported by that domain. For example, Azure has lot of sites, but these are not known to the ONAP. Any VNF placement in Azure sties is the job of Azure domain orchestrator. In “Multi-Cluster Orchestration” too, our thinking is similar to Azure and AWS, where it acts domain orchestrator and takes care of placement decisions for workloads within VNF/VF. And let the ONAP (SO/OOF) do the placement decisions across VNFs (in a service). I hope it helps and request others to comment.
