Personally, I'm not convinced the price will come down low enough for cloud functions/AWS lambda to ever be cost effective. We've looked at it + API gateway, and it would be orders of magnitude more expensive than our current giant amount of webservers.
Kubernetes (and similar technologies) on the other hand, make it possible to get the same economics as cloud functions while still tying your cost directly to the computing resources you use. Also, it gives you the freedom to (with some pain) move your entire platform to a different provider.
