I have developed a web service(using ruby/sinatra/sqs) which runs on Linux Red Hat. I am planning to move this on a EC2 instance. I see that Amazon provides a linux version of its own. Is there any reason why I should use Amazon Linux on EC2 instead of Red Hat?

I learned something new :) It's not the correct place because there are n't many sysadmins here. The guys over at Serverfault should be able to give you better answers. – Vladislav Zorov Nov 25 '11 at 13:22

Amazon's Linux AMI is most closely related to Centos, a Red Hat variant. The biggest benefit I've found from using it is their use of the pvgrub boot loader. It makes it trivial to compile and reboot into new or custom kernels.
Besides that, there are many nice-to-haves, such as patches being automatically applied on boot, having many AWS-related command line tools installed by default, and pre-configuration for in-cloud yum repositories.
