title: Solr and Zookeeper with a single node
body: <p>I have the setup of Solr cloud running in my local machine with the internal Zookeeper (i.e) Zookeeper that is being internally used by Solr with the single node.</p>
  
  <p>My query is that while I move my Solr to the production environment, Is it recommended to run the Zookeeper in a isolated/separate/external instance or is it better to go with the internal instance of Zookeeper that comes along with the Solr?</p>
