Advantage of Spring boot Actuator running on different port

Question

In Spring Boot, it is possible to have different ports for the server and management:

server.port=80
management.server.port=8081

What are the advantages and disadvantages of running Actuator (management) on different port to the server?

Answer 1

Probably others but how we used it is to limit access to the actuator. i.e. we expose server.port to the web but require VPN for access to the actuator.
