I really like this model for individual services.

The challenge I've always felt, is shared services -- if I'm running infra myself, I can depend upon it, but if someone else is running it, I'm never really sure if I can, which makes external services really hard to rely on and invest into.

Maybe you can get further than expected with individual services? But shared services at some point seem really useful.

I think web2 solved that in an unfortunate way, where you know the corporations operating the services / networks are aligned in some ways but not in others.

But would be great to have shared services that do have better guarantees. Disclaimer, we're working on something in that direction, but really curious what others have seen or thinking in this area.
