Finding just the right way to tell management it's time to re-architect the monolith and move into infra-as-code to become agnostic is the dream.

It's so rare, and apparently so unimportant, that I've never seen it as part of the marketing strategy.

Supabase. Big part of why they're heavily adopted. The only issue is that when their client gets big, they usually tend to leave Supabase for more proprietary hosting.

Allegedly Allscripts (now Veradigm) made their flagship products interoperable, the idea being that customers could choose to buy a giant ecosystem from them, or they could bolt on small solutions onto the giant monoliths that were their competition (like EPIC) and presumably get some revenue they weren't going to get otherwise.

Now - I never was tasked with actually using their software while I worked there, that was just the talking point in the town halls and all hands and such. Being able to export/import was part of that interoperability goal.
