I've worked with customers, clients, and partners throughout the Fortune 100 and public sector for my career and there's one thing that is consistent - there is NO consistency. Big companies have TONS of software from all sorts of places across their decades of M&A and partial-failure development efforts and re-orgs. The open source world is much more of a hive mind than big companies in many respects compared to programmers oftentimes locked in dungeons unable to escape their legacy codebases, tools, and architectures for arcane reasons like a manager liking the tie of a salesperson more than another. From a technical standpoint I'm constantly amazed at the sheer diversity / museum of stuff that'll get deployed to prod in the Fortune 100. Sure, 80%+ of the stuff made in the past 15 years is all Java crud, but the nice thing about that is that dropping wars into an application container is a very solved problem. I don't have to really think during another 90s-style deployment where more difficult problems are metaphysical like if I'm actually still myself from 20 years ago dreaming very hard that I'm living 20 years in the future and this is a side-effect of my 90s frame of mind.
