I'm new to Heroku and I'm trying to wrap my head around with it and I have seen that in demo here talks about the exposing the services in Heroku and expose your services like this:
my question is: What do I need to do in order to expose the Service
svc, do I have to write an application?
or if you have postgreSQL then it will expose automatically by configuring? those are the answers I'm trying to find, appreciate any help!
