I deployed Cisco CSR 1000V as edge router in DataCenter.
Deploying any variety of software-based router at one's edges is a mistake, and has been for many years.
The Cisco virtual stuff is great for labs, training, testing, and so forth - kudos to them for producing it, and I hope they do even more with their virtual versions.
That being said, there's no way I'd deploy any of it to route actual packets on actual production networks. Nothing against Cisco nor their virtual stuff, but in any kind of Internet-facing environment, software-only doesn't scale.
At some point in the future, this will change, as hardware-based routers/switches/whatnots will take the 'nFV' trend even further, and software hypervisor-based ones will gain direct, high-performance access to serious hardware-based NICs, NPUs, et. al. But for now, I personally think it's way too soon to be doing this in production environments.
