title: Tomcat vs Vert.x
body: <p>For the past few days I have been reading Vert.x documents. I know that Vert.x is polyglot, single threaded, non-blocking IO, modular architecture, high scalability. </p>
  
  <p>Is there any other major differences between tomcat and Vert.x?</p>
  
  <p>Also when we should use tomcat and when to use Vert.x?</p>
