Hosting "several hundred public domains" is not an easy task so, yes,
I would recommend you study DNS before (specially if it is a
commercial service). A server is either an authoritative server or a
resolver. An authoritative server does not handle recursive queries,
and does not send them. They just take one query and return one
response. Resolvers handle recursive queries and, in turn, query
authoritative name servers to get the responses.

If you like videos, see this one:

Some programs (BIND, and, in some way, Unbound), can do both
authoritative and resolver service but most people regard it as a bad
idea.

Then, you need authoritative servers. PowerDNS recursor is useless
here, and dnsdist is not mandatory. It could be cool but you can start
without it, just with PowerDNS authoritative.
