Last I talked to people about Apple's internal tooling, it was still pretty fragmented between different organizations.

I was told about e.g. multiple internal CI/build systems because one org didn't want to rely on the other, so they both built their own little software stacks.

That's a bit different than what I've heard from meta/google/amazon who seem to be more open to running centralized internal services

Amazon famously mandated such internal services at one point:

This was rather a long time ago now so I wouldn't be surprised if things have changed since then, though having never worked at Amazon I wouldn't know one way or the other.

The main thing that changed is that now the service approach also generally enforces a particular framework (Smithy/Coral)
