Ideally, managers create opportunities for people to exercise the former in a sandbox (e.g. some variation of "20% time"), without YAGNI-ing up the project.
Sorry did I say sandbox? I meant container.
Outsorcing became a Wall Street fad once a few big name companies did the numbers and found they could reduce costs by doing so.
Soon "everyone" was doing it, or announcing that they were going to, even though they had little to nothing to gain from it.
As that saying goes: when all you have is a hammer, every problem looks like a nail.
And right now that hammer, at least in terms of IT, seems to be containers.

Let's be fair, it's quite likely that if anyone is looking into this stuff is more because it's the technology du jour, rather then the off chance that they end up with 100 million users. It could be useful, and learning stuff is fun, but that's not the real drive.
Knowing the technology du jour is a lot more likely to get you a job, even if an older technology is better in some ways.
