We actually are only beginning a POC with AWS. the clustering I'm taking about right now are servers we are deploying in various regions our company operates in running in RHEL 7. thank you for the link, I will do the reading. And yes, Apache zookeeper, and that's what I thought as I read the site in that it was geared more toward file syncing.
