Is your RDS instance inside a VPC?

The simplest thing though is to use Elastic IP addresses for single instances that need to be reached from the outside world.

Are you just using a single instance? Why are you using auto-scaling? You can use auto-scaling in a min/max = 1 configuration to keep your single instance alive. When using a single instance, you can still benefit from ELB. ELB becomes your safety net and it avoids the need to do DNS changes. Another thing you can do is use an Elastic IP address to keep your IP constant.

Elastic Load Balancer is a front-end to a cluster of EC2 instances. It is the entry point for your users to access your web servers. Each instance does not need it's own public IP nor does it need it's own URL. That's ELB's job. It's the standard way to architect an auto-scaling group of web servers. Now, it's possible your use-case does not lend itself toward ELB, and that's what I was asking you to clarify.

Just because it's running nginx does not mean it needs a unique URL. It depends on how users will access your web server(s). If it's from a single URL and your multi-servers is to handle load, then no, you don't need individual URLs, you need a load balancer, such as ELB. But if your users access via www1.x.com, www2.x.com, etc., then yes. But if so, the question then is, why?

Why does the URL need to resolve to each instance individually?

Your problem is in the error message. You are specifying both EC2SecurityGroupName and EC2SecurityGroupId. For EC2 Classic, only specify EC2SecurityGroupName.

Why do you need a DNS record for each EC2 instance?

comment Amazon VPC NAT performance problems
It could be the network on your downloading instance and not the NAT. What type are those? Have you tried downloading to the same type from within a public subnet?
