title: AWS Elastic Beanstalk caching?
body: <p>I'm looking into hosting a standard Java web app on AWS and the new Elastic Beanstalk (<a href="http://aws.amazon.com/elasticbeanstalk/" rel="nofollow">http://aws.amazon.com/elasticbeanstalk/</a>) seems to have most of what we want. The one thing I can't figure out is how to do distributed caching. It seems that AWS doesn't allow multicast discovery of new nodes, so I'm not sure how new nodes started by the auto-scaling process should be integrated into an existing distributed cache. Any suggestions / best practices appreciated.</p>
  
  <p>Update: Ideally this would be a cache local to each application server instance. Best case scenario would be a hibernate level 2 cache config for something like ehcache or terracota.</p>
