I am a newbie in rails and need help in deploying the rails app to AWS.
need to set up the servers(unicorn and nginx) on AWS for a rails app.
i need to set up a staging environment for testing the app which should
accessible with a url like staging.sitename.com. Do i need to create
another instance and point the domain staging.sitename.com to this
for the staging env or it can be done with same instance ?
