How does a separate KTA web server communicate with the rest of the installation?

Question / Problem: 

How does a separate KTA web server communicate with the rest of the installation?

Answer / Solution: 

KTA web servers do not connect directly to the database.  Instead all work is performed through calls to the core services on the app server.  When a KTA web server is installed (without installing a combined web/app server), the installer prompts for the fully qualified address to an existing KTA app server:

This ends up setting the CoreServicesLocation setting in the web.config, seen here in the Configuration Utility:

This location can be either a single KTA app server, or a load balancer that has several app servers.

If the components of the app servers have been customized, this setting should point to app servers that have the WCF/Core Services installed:
