Advice needed! Service mapping - public facing web applications in the cloud

[Binglin Huang]

Trying to do service map for a web application that services the public. Can I achieve the service map by top-down discovery? And how should I setup the mid server? 

The service contains:

1. a public domain name /URL and associated public IP address

2. ELB AWS balancer behind the public IP

3. ELB AWS redirect traffics to web servers, then application and DB servers. All these servers are all inside the internal network hosted on AWS (not serverless)

Has anyone done service map similar to this this?

Your Mid Server will be Hosted in DMZ

Public URL is resolving by DNS on Public IP, then the  Traffic lands to LB. LB must be configured to route to actual servers. if DNS is set properly it should work.

If DNS is not resolving then u have to GRAB the LB URL and process just like Other Applications.

Thanks for the reply. But can you elaborate this part a bit? "u have to GRAB the LB URL and process just like Other Applications."
