In either case, though, it's an inside joke precisely because it's more relatable to those who are (or were) inside. In particular, I think it would be most funny to someone who was at Google about a decade ago; when I left Google in 2017 things had already changed enough that this didn't ring quite as true for new hires.
That said, GCP is not very representative of what the internal platform looked like circa 2010. (Or even of what the internal platform looks like now, as far as I know.)
Its fairly simple to extract the gist of what these systems from the script.
Requiring multi-cluster/region, the quota/resource economy system, handling PCRs, code review, readability approval for complex configuration languages (and the existence of such complex languages in the first place) ... all of that makes sense in a vacuum and all were built to handle real problems and are likely written in the blood of a near-miss outage. But it also all comes crashing down on you when you're doing things from scratch for a relatively simple usecase that no-one really designed for.
Exactly. This wasn't too relatable, even though I have the GCP Certified Architect cert.
