I need to provide my customers with fixed urls that don't change when the EC2 instances are stopped/started because sometimes we need to change the size of the EC2 and when we restart the instance the public IP has changed.
I thought on using Elastic IPs so I can keep the same public IP when the instance is rebooted, but I've seen that Amazon tells you that you only have 5 Elastic IPs. If you ask them they say that they can give you more, but I guess they're not giving you 10.000 of them.
How can I use a single public Elastic IP to give each user different URLs for out service?
It would be something like this, being 11.22.33.44 the Elastic IP and 192.168.0.X two EC2 instances:
11.22.33.44:**1000** --> 192.168.0.**1**:22
11.22.33.44:**1001** --> 192.168.0.**1**:80
11.22.33.44:**1002** --> 192.168.0.**1**:443
11.22.33.44:**1003** --> 192.168.0.**2**:22
11.22.33.44:**1004** --> 192.168.0.**2**:80
11.22.33.44:**1005** --> 192.168.0.**2**:443
I need to make it work programmatically, as I'm creating EC2 instances from the SDK as needed.
Another way I thought is using subdomains from my .com domain that points to the current public IP of each EC2 instance, but using the IP as I described before sounds better.
