I dono that I agree with the author's definition of DevOps - IMHO it's not that Dev is talking to Ops, there's nothing new there.

I think DevOps is something more akin to tackling operations problems from a developer's mindset. 'Infrastructure as Code' is a DevOps mantra.

A developer writes a program, runs the program on a compatible platform, and expects a certain output.

I think DevOps is - as an Ops guy you write a program, that program runs on a platform consisting of bare-metal machines, and the expected output is a platform for your developer's software to run on (i.e. configured & monitored web/proxy/db servers)
