title: What is the best library for Java to grid/cluster-enable your application?
body: <p>This is the ability to run your application on a cluster of servers with the intent to distribute the load and also provide additional redundancy.</p>
  
  <p>I've seen a presentation for <a href="http://www.gridgain.com/" rel="noreferrer">GridGain</a> and I was very impressed with it.</p>
  
  <p>Know of any others?</p>
