title: Netty bootstrap with boss group or with just with workers EventLoopGroup
body: <p>The book and examples indicates that we should use the so-called <code>boss</code> group and the <code>worker</code> group when bootstraping the server:</p>
  
  <pre><code>serverBootstrap.group(bossGroup, workerGroup);
  </code></pre>
  
  <p>And then, in the Vert.x that is based on Netty we have:</p>
  
  <pre><code>bootstrap.group(availableWorkers);
  </code></pre>
  
  <p>which mean (afaiu) that all workers is going to work the same, so no bosses to handle just the incoming connections.</p>
  
  <p>Why is that?</p>
