Others will comment I'm sure, but I'm suspicious the answer is that you can
only know by testing.

The kind and quantity of data in your indexes - the type of queries you
normally receive, etc, etc...

All these things will have an affect on your speed.

For sure you don't want 15 Zookeepers.  That will leave you with only one
dedicated Solr server.

In my experience, for production, you don't want Zookeeper and Solr on the
same box.

If others have different experience, I'm sure they'll share their opinions

I'd recommend starting with 3 Zookeepers (the minimum) on dedicated servers
(Zookeeper only)

Start with basic sharding (like what you mention -- 4 shards, 8 replicas)
and then load test.  You may find that some shards get much more traffic
than others do and in that case you'll want more replicas for those
shards...   It all depends on the patterns of use and the amount of data.
