title: Multiple clusters in kubernetes
body: <p>I am a newbie in kubernetes clustering. I have a simple question.
  I am in multiple kubernetes clustering. It seems multiple clusters are available in kubernetes. So "Multiple clustering" in kubernetes means:</p>
  
  <blockquote>
    <ul>
    <li>It is physical multiple clusters which have their own master, nodes?</li>
    <li>Or it's kind of "logical" multiple clustering in one physical clustering?(with one master and nodes)?</li>
    </ul>
  </blockquote>
  
  <p>Would you like to teach me? Thanks.</p>
