Am I correct that Tomcat is not setup to do load balancing without the
use of an Apache fronting? The mod_jk module is the best way to
load-balance requests on multiple servers using the Tomcat container,

David L. Whitehurst
Not exactly. Apache itself can't do load balancing. You could use a
dedicated Tomcat instance to loadbalance to backend Tomcats in the same
way as you described using Apache however either way you are still left
with a single point of failure. Neither Tomcat nor Apache can
loadbalance
