title: What load-balancing system do you use in production? What do you think of it?
body: <p>There are a lot of different systems for balancing load and achieving redundancy in production servers (Not just web servers)</p>
  
  <ul>
  <li>Round-robin DNS</li>
  <li>Linux Virtual Server</li>
  <li>Cisco Local Director</li>
  <li>F5 BigIP</li>
  <li>Windows NLB</li>
  <li>etc?</li>
  </ul>
  
  <p>If you use one of these (or another) in production, which one? How well does it work for you? Have you evaluated others?</p>
