Sorry , just a junior person here. Maybe a sr can pipe up later.
But my business cases and associated data points show NFV like SDN
are snake oil.
If you know your requirements, buy / implement the best value solution. You
can call it NFV if that makes you feel better.
There is nothing new under the sun. Running DNS or bgp on linux cough... is
not a new thing.
If you are google or fb and have the best software engineers in the world,
you can express your requirements to your dev team and they can just build
it. And support it.
But i see a lot of folks paying premium for sdn/nfv and tooting their own
horns ... but the needle is not moving
Buyer beware. Ymmv.
Ps. Also, simpler > complex. Lots of $ in this statement.
