Hi Rudra, We tried to separate policy from mechanism for this blueprint, and are trying to address the latter. I believe the logic for scaling, and or clustering multiple service VMs to map to a logical service instance would lie in the service plugin which realizes the logical service instance.
Can you please elaborate on the service/use-case where you would need to plug the VM into different networks? Thanks, ~Sumit.
