title: Image Upload Strategy with Clusters And Amazon S3
body: <p>Trying to sort out a strategy to deal with uploaded images whose endpoint is Amazon S3.  The goal is, upon upload, that the image is immediately visible.  However, the current way of handling the situation is that the end-user uploads the image and then has to wait for it to be synced to Amazon S3 before being able to view it.  The other option was to simply temporarily display the item locally, but since we are using a cluster, that doesn't really work, because the image would only, upon upload, be available for view on the cluster server it was uploaded to.  </p>
  
  <p>One possible solution was to rsync the files to Amazon immediately upon upload, but for some reason, rsyncing from within the script wasn't seeming to work.  Is that not possible within a PHP script?</p>
