PASE runs AIX, and is the avenue IBM’s taking these days to add cool new features. I did a quick Google for “erlang AIX”, and the results didn’t look promising. There’s a push to add Docker support to IBM i, but IBM hasn’t committed to it.
FWIW, like “AS/400”, the term “OS/400” is long obsolete, and would be roughly equivalent to a Windows admin saying she runs Windows NT servers.
