Load balancing with an Undertow subsystem

Considering the fact that we have two running undertow instances, we will configure a WildFly application server Undertow subsystem to act as a load balancer in the following section. Start two instances of the beosbank-undertow-service project using the following:

$mvn exec:java -Dundertow.port=7071
$mvn exec:java -Dundertow.port=7072

Download, install, and run a WildFly application server in standalone mode:

unzip $HOME/Downloads/wildfly-11.0.0.Alpha1.zip
cd wildfly-11.0.0.Alpha1/bin
$ ./standalone.sh

WildFly is now running and listening on port 9990; connect to the server using jboss-cli, as follows:

./jboss-cli.sh --connect

For Undertow to act as a static load balancer behind a set of backend systems, we must register remote socket bindings for these backend systems:

[standalone@localhost:9990 /] /socket-binding-group=standard-sockets/remote-destination-outbound-socket-binding=node1/:add(host=localhost,port=7071)
{"outcome" => "success"}
[standalone...
