That somewhat mirrors my take on it. At the risk of being flamed to hell,
I see SDN/NFV being to network operations as DevOps/CI/CM/containers are to
dev and systems. Both are bringing in new tools and such, but ultimately
they *require* solid automation and having your house (systems, processes
workflow) in order to be able to deploy, with the hype train providing
budget allocation and sufficient buy-in to get it to fly.
You can do network automation and service provisioning without NFV and
centralized SDN controllers, and you can do CM and good tooling without
going headlong into DevOps. Obviously SDN/NFV and DevOps have their own
pieces that layer on top of that (e.g. control plane / forwarding plane
separation and commoditization of the forwarding hardware in the former;
development model and "culture" in the latter), and you have to sift
through the hype and buzzword bingo to find what if any of that would
deliver value in your environment. But, that doesn't mean we can't benefit
from the advances and possible standardization in tooling and automation
that come along for the ride.
