Loadbalancer infront of remedy webservers(midtier):
External system connects to loadbalancer IP.
Loadbalancer gets the traffic from external system. Replaces the
external systems IP address with loadbalancer IP and forwards it to remedy
webserver.
Webserver talks to arserver and sends the request.
ARServer process the request and sends the results to webserver.
Webserver will send it to loadbalancer.
Loadbalancer replaces the sourceIP(remedy webservers IP) to
loadbalancers IP and sends it to external system.
In this scenario external system knows only about load balancer IP. It
does not know about remedy webserver or arserver.
Since the external system sends data to loadbalancer IP, it can only
receive results from the same IP.
So the communication is between:
1) External system and loadbalancerIP bidirectional.
2) Loadbalancer IP and remedy webserver bidirectional.
3) Remedy webserver and ARServer bidirectional.
