You run N number of Solr nodes depending on your needs. For a HA environment, you run one or more shards (depending on size of data), and three or more replica's. These are all Solr nodes. You need three Zookeepers at least for proper HA. > > 2. Each node and zookeeper process ideally runs on it's own physical server? Doesn't need to be physical, virtual is fine. Zookeeper can run on small VM's without issues. > > 3. Searches can be sent to any of the node processes? Yes. > > 4. A typical HA configuration would put a proxy or load balancer out > in front of the nodes to distribute the work? Yes, or a cluster-aware client, such as SolrJ if your application uses Java. > > Ken >
