Project Shoal implements a novel way to cluster multiple Glassfish appserver instances using the JXTA technology. Leveraging the JXTA self-organizing and dynamic group networking infrastructure, Project Shoal allows administrators to easily deploy and dynamically group Glassfish appserver instances into a cluster. Project Shoal highly-decentralized implementation removes the traditional cluster Master single point of failures and control by decentralizing the Master function accross all instances. Any instance can take over Master responsability, if the existing Master fails. New instances can be added dynamically on-demand enabling massive-scale appserver clustering deployment.
