Elastic Scaler Design

Version 1

    Based on http://community.jboss.org/message/526687


    Use rules/CEP to collect data from mod_cluster: http://www.jboss.org/mod_cluster/java/load.html

    Rules can then be applied to decide if it is time to scale up or scale down the cluster.

    Additional rules can kick in when a new node is required - to see if it can be multi tenanted on an existing instance.
