SolrCloud is designed around the idea that each machine runs one copy of Solr. Running multiple instances of Solr on one machine is usually a waste of resources, and can lead to problems with SolrCloud high availability (redundancy). Here's a simple way of thinking about the terminology in SolrCloud: Collections are made up of one or more shards. Shards have one or more replicas. Each replica is a core. An important detail: For each shard, one of the replicas is elected leader. SolrCloud gets rid of the master and slave concepts. Thanks, Shawn
