Hi Daniel, In that case, it is safe to assume that ?vf module? is a single VM and VNF is a collection of one-or-more VMs that provide a specific network function?

A service contains one or more vnfs and a vnf has one or more vf modules. A vf module is the smallest component of a vnf (so think of a single load balancer in a load balancer vnf) and has a heat template for it. A vnf is a sum of those parts to create a network function, ie a load balancer may be split into l4 and l7 with a vf module for each l4 and then a vf module for each l7. The service has one or more vnfs in it and is what is actually deployed to the network. Ie if a web stack service is what you want, it may have a load balancer vnf (from above) and the app server vnf behind that are connected in a service chaining approach to actually make the service you deploy.

Is my understanding correct? Thanks for the pointer to the tutorial, I just skimmed through it and it looks like VF module configuration will be handled using directed graphs and need not be a part of the MSO workflow.

I am looking at the BPMN flows in MSO to understand the end-to-end workflows for creation of service instance, VNF and VF modules. I see that MSO creates entries in AAI Inventory. The calls to SDNC exist however the SDNC interaction is disabled [1]. What is the reasoning behind doing so? If we need to include SDNC/APPC in the workflow for example to mount and perform configuration on the VNF instead of relying on robot, how can this be achieved.
