Making an application at ec2 accessible from the Internet

I have an ec2 free instance working as well as elastic IP, S3 and RDS. There is a folder with the sources of my application at /home/ubuntu. I run a built-in server inside this folder:

$ /home/ubuntu/my_app play run

It's running at port 9000 (at my_app folder). I have A and CNAME records at route53, but they point to the static html pages-stubs at s3, I did it for simplicity and, of course, they shouldn't point to the static pages.

I wonder, how do I make this running Play application visible from outside? I have no idea where in ec2 (or in route53) look for and set it. Obviously, I want it to be accessible as my_custom_domain.com (which I have) without specifying the port (my_custom_domain.com:9000).

  1. To change your port from 9000 to 80 - If you work on ubuntu you can use iptables

    sudo iptables -t nat -I PREROUTING -p tcp --dport 80 -j REDIRECT --to-ports 9000

    This will route all traffic coming from port 9000 to port 80

  2. To map your elastic IP to my_custom_domain.com from the documentation:

Create a resource record set in your hosted zone. For Type, choose A – Ipv4 address. For Value, specify the Elastic IP address for your Amazon EC2 instance. For more information about creating a resource record set, see Working with Resource Record Sets.

If you want to run several applications on the same server, each on a different port, but serve them each on a different DNS (for example: http://www.my_domain.com for port 8080, and http://m.my_domain.com for port 8081), you might want to use ELBs which can do port forwarding from port 80 to the application port.

With this configuration you can map each ELB as an Alias on a Route 53 Record Set.
