Yes it is one installation. Created a wordpress install on one server, then use GIT repo to push changes to production server. That way the back end has its on server and can test changes before pushing it to the production server. It is amazon elastic beanstalk. It keeps the website scalable because at any moment the production server can be terminated and another one will replace it. They use a different URL structure, that was what I was trying to portray with my specific question. The production server doesn’t have a /BASE/, the management server has a /BASE/.
The management server is guarded off in a private network.
