So he is full of it. DevOps is not about ops engaging with devs. It's about making all devs part of ops. It's a model which existed in commercial banks and other places which could afford to overpay (a lot) to have people do work a few notches below the pay grade they are paid. But it's high stress and snail-pace progress. It reduces specialization which, by definition, makes experience less valuable. It puts all of the testing burden on the developers and removes testing specialists. In the most extreme cases, it flattens the most experienced developers and newly minted college interns into doing the same job. The result is that the quality of the product is always determined by what the least skilled members of the team can handle. Oh, and because everyone is resentful and knows that they are overqualified, it creates a frat-house-like environment. Everyone end up overworked and under accomplished. But because it's used in the cloud management now (an industry growing quickly so it has as much money to burn as the banks), it creates the illusion of being successful. It's not.
The cloud started before there was dev ops. And it would continue and succeed without dev ops. It exists because all development is network development (to at least some degree) because CPUs can't be made much more powerful, they can only be networked on the chip (aka multi-core CPUs, GPU). And if there is no distinction between pooling multi-computer resources and pooling multi-core resources, then scaling is accomplished by pooling a lot of them in near-real-time batch processing (aka pipeline). Which means the state of technology makes the cloud computing model make more sense than stand-alone units computing model. The state of technology is what drives the business incentive here. And the business incentive is what creates the illusion that the fulfillment model of the business incentive is the right one. Even if it's not organization model. Poorly chosen organization model in the environment of over-funding will not fail until the market place becomes more efficient and consolidates. And at that time, all the DevOps shops will be unable to support their costs and won't understand why everyone is switching to well-engineered (through full SDLC) products. They'll be saying it's not in vogue anymore. While the reality is that DevOps is just an inefficient organizational model to develop cloud services.
You have obviously never eaten a $100 hamburger.
Not everyone enjoys slamming, you know. Sure the chicks are to impress, but after a while you feel like "what's the point?"... Wait, you meant $100-burger as a luxury, didn't you? Um... I gotta go.
If it's worth doing, it's worth doing for money.
