We are currently using solr without cloud with 500 cores. It works good.
Now we are planning to expand it using solr cloud with 1000 cores, (2 cores

SolrCloud starts having scalability issues once you reach a few hundred
collections, regardless of how many servers are in the cloud.
I explored this in SOLR-7191. You might notice that the issue is in a
"Resolved/Fixed" state ... but there were no changes committed, and when
I tested it again with a later version, I saw evidence that the
situation has gotten worse, not better.

If you already have mechanisms in place to handle high availability, you
would be far better off NOT using SolrCloud mode.
