I have downloaded and installed Pega Personal Edition in an AWS EC2 instance. I have a developer who lives remotely and I would like for him to access the application as well so that he can develop in Dev Studio. How can I enable a link for him to log on in a different remotely? So we can both pretty much develop at the same time with two different operator ID's. I am using PostgresSQL as DB server and Tomcat as app server.
