You're correct in that Apple doesn't manufacture server hardware like the Xserve anymore, but OS X, Server edition is still available and it will manage Apache for you (albeit in a terrible way, I don't like the excessive configuration they apply)

Many of Apple's own web sites run Apple hardware for outward facing, large scale serving (I used to work there).

At the end of the day, Unix is Unix.

I run nginx on OS X on a number of Mac Minis without issue and long uptimes.

Does that mean Mac Mini? Or Custom Hardware like Xserve.

Oh, back then it was a wall full of XServes. These days, if they run Macs, they're probably racking Mac Pros.
