Actually, where it runs is quite relevant due to the economies of scale you get from jamming everything into centralized, standardized, efficient, virtualized spaces where heavy investment into automation, resilience, and predictability make sense. Whereas it may have taken a team to keep a handful of application and database servers up and running in the past with other teams responsible for dev, qa, integration, design, etc, a back-end team of the same size (with sufficient talent) can now manage thousands of similar systems with a fraction of the infrastructure. What's more, devs now merely have a platform for all their code to conform to, so there's no more opportunity (or real need) for customized architectures and integration. Here's your collection of Windows/Linux boxes. Now make your shit go. So a good chunk of the rest of those teams can go bye-bye too.
All this means less people on both sides of the table as the equations get exponentially simpler and more efficient. However, it does mean you need everyone who's left to be people who are at the top of their game. So if you aren't already top talent, it's time to move as fast as you can to become that. The days of CYA, laying low, and riding the wave of inefficiency by flying under the radar are running out in a lot of places. If you're a superstar with useful skills in the new model who stands out to people, you'll have a home (and you're probably going to see your income climb if you're smart about your career path). If you aren't, you're going to be standing in lines for a while until you figure out what's next.
