Hi Raffi, That's a very sensible approach to scaling up the capacity of your system. Because you are embedding Neo4j, you can simply switch to using HighAvailabilityGraphDatabase instead of EmbeddedGraphDatabase, as described here: http://wiki.neo4j.org/content/High_Availability_Cluster
You will first need to configure the Zookeeper cluster, and each Neo4j HA instance. Do you anticipate continuing to host each application within Tomcat? What will you use for load-balancing?
