Standalone Topology:-
For Test environment, we only have a single frontend server to host the Edge UI, Developer Portal, Router/Message Processor. Is it possible to achieve TLS (HTTPS connection) using the default port 443 itself for all these components? Or will it cause conflict as two or more components cannot listen to port 443 at the same time? How can we achieve this since we can only have port 443 exposed to outside world.
5 host installation topology:-
Do we require a load balancer for the Router/Message Processor cluster? In case of 5 host installation, where can we install Developer Portal? Do we need a 6th server for that?
