No and no. It has no metadata of its own (it just helps map from
something a human understand to what the SP needs to know: the IDP's
entityID), and it does not need to be on a seperate host.

In fact best practices suggest not to run a discovery service that is
recognizable as something different from the application / the SP,
cf. https://discovery.refeds.org/

If you're running a disovery service shared by many (and closely
related) services / SPs the situation is a bit different, of course.
