You can configure virtual hosting merely by configuring several
entries in conf/server.xml. Ths host manager may not be necessary.

A single cluster can be configured in conf/server.xml that will cover
all virtual hosts in an if you make sure to configure the
as a child of the element. If you'd like separate
configurations for each virtual host, you may configure
sepearate elements as child elements of each element.

You will want to enable the RemoteIPValve. You can read about it here:
http://tomcat.apache.org/tomcat-8.5-doc/config/valve.html#Remote_IP_Valv

That's up to you. If you intend to use your LB for all virtual hosts
(which is usually a good idea for HA), then configure it globally.

You may want to consider using HTTPS internally on your network
instead of (plaintext) HTTP, and you may also want to consider
enabling the EncryptionInterceptor for your cluster. That way, none of
your internal communications are in the clear vulnerable to
interception or modification within your network.
Hope that helps,
