Which application should be used to externally access all applications deployed in the same host machine with a single public IP address and port, when each application listens on different local ports?
A reverse proxy can be used to route external requests to different applications on the same host machine using a single public IP address and port. It forwards the requests to the appropriate backend servers based on the request URL or other routing rules.
Single Entry Point: A reverse proxy serves as a single entry point to multiple applications, making it ideal for managing traffic to multiple services hosted on the same machine.
Routing Requests: It can route requests to different internal ports based on the requested URL or other criteria.
Option A is the correct choice as a reverse proxy handles external access to multiple applications on the same host.
