EC2 and NAT

Amazon just added NAT to their EC2 service. It also sounds like they will be turning the old direct addressing scheme off soon. This is probably a step towards assigning static IPs to your hosts in EC2. It may even allow you to have EC2 instances with no external IP address at all. It makes sense to not use an external IP when all you are doing is processing data from S3 and then sticking it back into S3. You can read more about the NAT change here.

I managed to find a Debian image that is pretty small and decided to see if I could make it work for EC2.

Creating your own FC6 instance for EC2

I've been playing around with the EC2 service at Amazon and figured I would document a little about how you create your own FC6 AMI. The Amazon documentation goes over everything you need to know about creating your own FC4 AMI and if you don't want to roll your own you can use one of the public AMIs. Amazon just started letting people publish their own AMIs on their site so you should expect to see more as time goes by.
