I see cloud-native as NFV++. It requires some adjustment to how classic
NFV has been deployed, and that comes down to whether operators
(especially those who err on the side of network operations rather than
services) see value in upgrading their stack to cloud-native.

If you're a Netflix or an Uber, sure, a cloud-native architecture is
probably the only way you can scale. But if you are simple network
operators who focus more on pushing packets than over-the-top services,
particularly if you already have some NFV, making the move to
cloud-native/NFV++ is a whole consideration.
