Amazon EC2 Free - Ports

Question

I have a small c# server that allows silverlight clients to connect to it. Would I be able to host the server on a free 'EC2 running Microsoft Windows Server Micro' (Free signup gives you 750hr/mon of that for a year)? I guess im asking if I could setup port 4530 on the server for I could communicate. Would I need a dedicated IP to do this? (Which I assume isn't in the 'free' stuff), or if its not a dedicated, am I able to 'register' that port for data coming in knows to go to my 'server'?

Answer 1

Unless I'm missing something, a Micro instance is still an instance... meaning it is a full virtual machine that just happens to have minimal resources (CPU, memory, and IO).

You should be able to allow any port you like using the Amazon instance management tools (you'll need to specifically allow that port for the relevant security group for your instance).

UPDATE (based on sdolgy's comment)

You get an Elastic IP for you instance, meaning an IP address that remains constant even if eg your instance is moved within the AWS data center, the elastic IP remains the same. You can manage elastic IP's via the AWS control panel.
